Papaver somniferum | |
Papaver somniferum, commonly known as the opium poppy [2] or breadseed poppy, [3] is a species of flowering plant in the family Papaveraceae. It is the species of plant from which both opium and poppy seeds are derived and is also a valuable ornamental plant grown in gardens. Its native range was east of the Mediterranean Sea, but has since been obscured and vastly expanded by introduction and cultivation from ancient times to the present day, being naturalized across much of Europe and Asia.
This poppy is grown as an agricultural crop on a large scale, for one of three primary purposes: to produce poppy seeds, to produce opium (for use mainly by the pharmaceutical industry), [4] and to produce other alkaloids (mainly thebaine and oripavine) that are processed by pharmaceutical companies into drugs such as hydrocodone and oxycodone. [4] Each of these goals has special breeds that are targeted at one of these businesses, and breeding efforts (including biotechnological ones) are continually underway. [4] [5] [6] A comparatively small amount of P. somniferum is also produced commercially for ornamental purposes.
Today many varieties have been bred that do not produce a significant quantity of opium. [3] [5] The cultivar 'Sujata' produces no latex at all. [6] Breadseed poppy is more accurate as a common name today because all varieties of P. somniferum produce edible seeds. This differentiation has strong implications for legal policy surrounding the growing of this plant. [5]
Papaver somniferum is an annual herb growing to about 100 centimetres (40 inches) tall. The plant is strongly glaucous, giving a greyish-green appearance, and the stem and leaves bear a sparse distribution of coarse hairs. The large leaves are lobed, the upper stem leaves clasping the stem, [7] the lowest leaves with a short petiole. [8] : 40 The flowers are up to 3–10 cm (1–4 in) diameter, normally with four white, mauve or red petals, sometimes with dark markings at the base. The fruit is a hairless, rounded capsule topped with 12–18 radiating stigmatic rays, or fluted cap. [9] All parts of the plant exude white latex when wounded. [7] : 93 [10] : 32
The alkaloids are organic nitrogenous compounds, derivatives of secondary metabolism, synthesized through the metabolic pathway of benzylisoquinoline. [11] First, the amino acid phenylalanine, through the enzyme phenylalanine hydroxylase, is transformed into tyrosine. Tyrosine can follow two different routes: by tyrosine hydroxylase it can form L-dopamine (L-DOPA), or it can be reduced to form 4-phenylhydroxyacetaldehyde (4-HPAA). Subsequently, L-DOPA reacts with 4-HPAA and, through a series of reactions, forms (S) -norcoclaurine, which carries the benzylisoquinoline skeleton that gives its name to this pathway. The conversion of (S) -norcoclaurin to (S) -reticuline is one of the key points, since from (S) -reticuline morphine can be formed through the morphinan route, noscapine through the path of the noscapina or berberina. [11]
The poppy genome contains 51,213 genes encoding proteins distributed 81.6% in 11 individual chromosomes and 18.4% remaining in unplaced scaffolds. [11] In addition, 70.9% of the genome is made up of repetitive elements, of which the most represented are the long terminal repeat retrotransposons. This enrichment of genes is related to the maintenance of homeostasis and a positive regulation of transcription. [11]
The analysis of synergy of the opium poppy reveals traces of segmental duplications 110 million years ago (MYA), before the divergence between Papaveraceae and Ranunculaceae, and an event of duplication of the complete genome makes 7.8 MYA.
The genes are possibly grouped as follows: [11]
Papaver somniferum was formally described by the Swedish botanist Carl Linnaeus in his seminal publication Species Plantarum in 1753 on page 508. [12] [13]

P. somniferum has had a very long tradition of use, starting in the Neolithic. This long period of time allowed the development of a broad range of different forms. In total there are 52 botanical varieties. [14] Breeding of P. somniferum faces a challenge caused by the contradictory breeding goals for this species. [14] On one hand a very high content of alkaloids is requested for medical uses. The global demand for the alkaloids and the pharmaceutical derivatives has increased in the past years. Therefore, there is a need for the development of varieties with a high opium yield. [15] On the other hand, the food industry demands as low alkaloid contents as possible. [14]
There is one accepted subspecies, P. somniferum subsp. setigerum (DC.) Arcang. [12] There are also many varieties and cultivars. Colors of the flowers vary widely, as do other physical characteristics, such as number and shape of petals [ citation needed ], number of flowers and fruits, number of seeds, color of seeds, and production of opium. Papaver somniferum var. paeoniflorum is a variety with flowers that are highly double, and are grown in many colors. P. somniferum var. laciniatum is a variety with flowers that are highly double and deeply lobed. The variety Sujata produces no latex and no commercial utility for opioid production.
The native range of opium poppy is probably the Eastern Mediterranean, but extensive cultivation and introduction of the species throughout Europe since ancient times have obscured its origin. It has escaped from cultivation, or has been introduced and become naturalized extensively in all regions of the British Isles, particularly in the south and east [16] and in almost all other countries of the world with suitable, temperate climates. [17]
P. somniferum is susceptible to several fungal, insect and virus infections including seed borne diseases such as downy mildew and root rot. The use of pesticides in combination to cultural methods have been considered as major control measures for various poppy diseases. [18]
The fungal pathogen Peronospora arborescens , the causal agent of downy mildew, occurs preferentially during wet and humid conditions. [19] This oomycete penetrates the roots through oospores and infects the leaves as conidia in a secondary infection. [20] The fungus causes hypertrophy and curvature of the stem and flower stalks. [21] The symptoms are chlorosis and curling of the affected tissues with necrotic spots. [22] The leaf under-surface is covered with a downy mildew coating containing conidiospores that spread the infection further leading to plant damage and death. [23] Another downy mildew species, Peronospora somniferi , produces systemic infections leading to stunting and deformation of poppy plants. [24] Downy mildew can be controlled preventively at the initial stage of seed development through several fungicide applications. [19]
Leaf blight caused by the fungus Helminthosporium papaveris is one of the most destructive poppy diseases worldwide. The seed-borne fungus causes root rot in young plants and stunted stems in plants at a higher development stage, where leaf spots appear on the leaves and is being transmitted to capsules and seeds. [23] Early sowing of seeds and deep plowing of poppy residues can reduce fungal inoculum during the plant growing season in the following year on neighboring poppy stocks, respectively. [19]
Mosaic diseases in p. somniferum are caused by rattle virus and the Carlavirus. [18] In 2006, a novel virus tentatively called "opium poppy mosaic virus" (OPMV) from the genus Umbravirus was isolated from p. somniferum containing leaf mosaic and mottling symptoms, in New Zealand. [25]
There are only a few pests that can do harm to P. somniferum. [19]
Flea beetles perforate the leaves of young plants and aphids suck on the sap of the flower buds. [19] The poppy root weevil ( Stenocarus ruficornis ) is another significant pest. The insect lives in the soil and migrates in spring to the poppy fields after crop emergence. Adults damage the leaves of small plants by eating them. Female lay their eggs into the tissue of lower leaves. Insect larvae hatch and burrow into the soil to complete their life cycle on the poppy roots as adults. [26]
In the growth development of P. somniferum, six stages can be distinguished. The growth development starts with the growth of the seedlings. In a second step the rosette-type leaves and stalks are formed. After that budding (hook stage) takes place as a third step. The hook stage is followed by flowering. Subsequently, technical maturity is reached, which means that the plant is ready for cutting. The last step is biological maturity; dry seeds are ripened. The photoperiod seems to be the main determinant of flower development of P. somniferum. [27]
P. somniferum shows a very slow development in the beginning of its vegetation period. Due to this fact the competition of weeds is very high in early stages. It is very important to control weeds effectively in the first 50 days after sowing. [28] Additionally, Papaver somniferum is rather susceptible to herbicides. The pre-emergence application of the herbicide chlortoluron has been shown to be effective in reducing weed levels. [28] However, in the last decade the weed management of Papaver somniferum has shifted from pre-emergence treatments to post-emergence treatments. [29] Especially, the application of the two herbicides mesotrione and tembotrione has become very popular. The combined application of those two herbicides has been shown to be recommendable for effective weed management in Papaver somniferum. [29] Sowing time (autumn or spring), preceding crop and soil texture are important variables influencing the weed species composition. A highly abundant weed species in Papaver somniferum fields was shown to be Papaver rhoeas . [29] [30] Papaver somniferum and Papaver rhoeas are congeners and belong to the same plant family, which impedes the chemical control of this weed species. [30] Therefore, weed management represents a big challenge and requires technological knowledge from the farmer. [30] In order to increase the efficiency of weed control not only chemical weed control should be applied but also mechanical weed control. [30]
For P. somniferum, a growth density of 70 to 80 plants per square meter is recommended. [31] Latex-to-biomass yield is greatest under conditions of slight water deficit. [32]
Live plants and seeds of the opium poppy are widely sold by seed companies and nurseries in most of the western world, including the United States. Poppies are sought after by gardeners for the vivid coloration of the blooms, the hardiness and reliability of the poppy plants, the exotic chocolate-vegetal fragrance note of some cultivars,[ which? ] and the ease of growing the plants from purchased flats of seedlings or by direct sowing of the seed. Poppy seed pods are also sold for dried flower arrangements.
Though "opium poppy and poppy straw" are listed in Schedule II of the United States' Controlled Substances Act, P. somniferum can be grown legally in the United States as a seed crop or ornamental flower. [33] During the summer, opium poppies can be seen flowering in gardens throughout North America and Europe, and displays are found in many private plantings, as well as in public botanical and museum gardens such as United States Botanical Garden, Missouri Botanical Garden, and North Carolina Botanical Garden.
Many countries grow the plants, and some rely heavily on the commercial production of the drug as a major source of income. As an additional source of profit, the seeds of the same plants are sold for use in foods, so the cultivation of the plant is a significant source of income. This international trade in seeds of P. somniferum was addressed by a UN resolution "to fight the international trade in illicit opium poppy seeds" on 28 July 1998.

In 2018, world production of poppy seeds for consumption was 76,240 tonnes, led by Turkey with 35% of the world total (table). Poppy seed production and trade are susceptible to fluctuations mainly due to unstable yields. The performance of most genotypes of Papaver somniferum is very susceptible to environmental changes. [35] This behaviour led to a stagnation of the poppy seed market value between 2008 and 2009 as a consequence of high stock levels, bad weather and poor quality. [36] The world leading importer of poppy seed is India (16 000 tonnes), followed by Russia, Poland and Germany. [37]
Poppy seed oil remains a niche product due to the lower yield compared to conventional oil crops. [38]
Australia (Tasmania), Turkey and India are the major producers of poppy for medicinal purposes and poppy-based drugs, such as morphine or codeine. [39] [15] The New York Times reported, in 2014, that Tasmania was the largest producer of the poppy cultivars used for thebaine (85% of the world's supply) and oripavine (100% of the world's supply) production. Tasmania also had 25% of the world's opium and codeine production. [4]
In most of Central and Eastern Europe, poppy seed is commonly used for traditional pastries and cakes, and it is legal to grow poppies throughout the region, although Germany requires a licence. [40]
Since January 1999 in the Czech Republic, according to the 167/1998 Sb. Addictive Substances Act, poppies growing in fields larger than 100 square metres (120 sq yd) is obliged for reporting to the local Custom Office. [41] [42] Extraction of opium from the plants is prohibited by law (§ 15 letter d/ of the act). It is also prohibited to grow varieties with more than 0.8% of morphine in dry matter of their capsules, excluding research and experimental purposes (§24/1b/ of the act). The name Czech blue poppy refers to blue poppy seeds used for food.[ citation needed ]
The United Kingdom does not require a licence for opium poppy cultivation, but does for extracting opium for medicinal products. [43]
In the United States, opium poppies and poppy straw are prohibited. [44] As the opium poppy is legal for culinary or esthetic reasons, poppies were once grown as a cash crop by farmers in California. The law of poppy cultivation in the United States is somewhat ambiguous. [45] The reason for the ambiguity is that the Opium Poppy Control Act of 1942 (now repealed) [46] [47] stated that any opium poppies should be declared illegal, except if the farmers were issued a state permit. § 3 of the Opium Poppy Control Act stated:
It shall be unlawful for any person who is not the holder of a license authorizing him to produce the opium poppy, duly issued to him by the Secretary of the Treasury in accordance with the provisions of this Act, to produce the opium poppy, or to permit the production of the opium poppy in or upon any place owned, occupied, used, or controlled by him.
This led to the Poppy Rebellion, and to the Narcotics Bureau arresting anyone planting opium poppies and forcing the destruction of poppy fields of anyone who defied the prohibition of poppy cultivation. [48] [49] Though the press of those days favored the Federal Bureau of Narcotics, the state of California supported the farmers who grew opium poppies for their seeds for uses in foods such as poppy seed muffins. Today, this area of law has remained vague and remains somewhat controversial in the United States. [50] The Opium Poppy Control Act of 1942 was repealed on 27 October 1970. [51] [52]
Under the Federal Controlled Substances Act, opium poppy and poppy straw are listed as Schedule II drugs under ACSN 9630. Most (all?) states also use this classification under the uniform penal code. Possession of a Schedule II drug is a federal and state felony.
Canada forbids possessing, seeking or obtaining the opium poppy (Papaver somniferum), its preparations, derivatives, alkaloids and salts, although an exception is made for poppy seed. [53]
In some parts of Australia, P. somniferum is illegal to cultivate, but in Tasmania, some 50% of the world supply is cultivated. [54]
In New Zealand, it is legal to cultivate the opium poppy as long as it is not used to produce controlled drugs. [55]
In United Arab Emirates the cultivation of the opium poppy is illegal, as is possession of poppy seed. At least one man has been imprisoned for possessing poppy seed obtained from a bread roll. [56]
Burma bans cultivation in certain provinces. In northern Burma bans have ended a century-old tradition of growing the opium poppy. Between 20,000 and 30,000 former poppy farmers left the Kokang region as a result of the ban in 2002. [57] People from the Wa region, where the ban was implemented in 2005, fled to areas where growing opium is still possible.
In South Korea, the cultivation of the opium poppy is strictly prohibited. [58]

Use of the opium poppy predates written history. The making and use of opium was known to the ancient Minoans. [59] Its sap was later named opion by the ancient Greeks. The English name is based on the Latin adaptation of the Greek form. Evidence of the early domestication of opium poppy has been discovered through small botanical remains found in regions of the Mediterranean and west of the Rhine River, predating circa 5000 BC. [60] These samples found in various Neolithic sites show the incredibly early cultivation and natural spread of the plant throughout western Europe.
Opium was used for treating asthma, stomach illnesses, and bad eyesight.
Opium became a major colonial commodity, moving legally and illegally through trade networks on the Indian subcontinent, Colonial America, Qing China and others. [61] Members of the East India Company saw the opium trade as an investment opportunity beginning in 1683. [62] In 1773, the Governor of Bengal established a monopoly on the production of Bengal opium, on behalf of the East India Company administration. The cultivation and manufacture of Indian opium was further centralized and controlled through a series of acts issued between 1797 and 1949. [62] [63] East India Company merchants balanced an economic deficit from the importation of Chinese tea by selling Indian opium which was smuggled into China in defiance of Qing government bans. This trade led to the First and Second Opium Wars. [64] [63] [61] [65]
Many modern writers, particularly in the 19th century, have written on the opium poppy and its effects, notably Thomas de Quincey in Confessions of an English Opium Eater .
The French Romantic composer Hector Berlioz used opium for inspiration, subsequently producing his Symphonie Fantastique. In this work, a young artist overdoses on opium and experiences a series of visions of his unrequited love.
In the US, the Drug Enforcement Administration raided Thomas Jefferson's Monticello estate in 1987. It removed the poppy plants that had been planted continually there since Jefferson was alive and using opium from them. Employees of the foundation also destroyed gift shop items like shirts depicting the poppy and packets of the heirloom seed. [66]
Poppy seeds from Papaver somniferum are an important food item and the source of poppy seed oil, an edible oil that has many uses. The seeds contain very low levels of opiates and the oil extracted from them contains even less. [67] Both the oil and the seed residue also have commercial uses.
The poppy press cake as a residue of the oil pressing can be used as fodder for different animals as e.g., poultry and fancy fowls. Especially in the time of the molt of the birds, the cake is nutritive and fits to their special needs. Next to the animal fodder, poppy offers other by-products. For example, the stem of the plant can be used for energy briquettes and pellets to heat. [19]
Poppy seeds are used as a food in many cultures. They may be used whole by bakers to decorate their products or milled and mixed with sugar as a sweet filling. They have a creamy and nut-like flavor, and when used with ground coconut, the seeds provide a unique and flavour-rich curry base. They can be dry roasted and ground to be used in wet curry (curry paste) or dry curry. [68]
When the European Union attempted to ban the cultivation of Papaver somniferum by private individuals on a small scale (such as personal gardens), citizens in EU countries where poppy seed is eaten heavily, such as countries in the Central-Eastern region, strongly resisted the plan, causing the EU to change course. Singapore, UAE, and Saudi Arabia are among nations that ban even having poppy seeds, not just growing the plants for them. [69] The UAE has a long prison sentence for anyone possessing poppy seeds. [70]
The opium poppy is the principal source of opium, the dried latex produced by the seed pods. Opium contains a class of naturally occurring alkaloids known as opiates, that include morphine, codeine, thebaine, oripavine, papaverine and noscapine. [71] [72] The specific epithet somniferum means "sleep-bringing", referring to the sedative properties of some of these opiates. [73]
The opiate drugs are extracted from opium. The latex oozes from incisions made on the green seed pods and is collected once dry. Tincture of opium or laudanum, consisting of opium dissolved in alcohol or a mixture of alcohol and water, is one of many unapproved drugs regulated by the U.S. Food and Drug Administration (FDA). Its marketing and distribution persists because its historical use preceded the Federal Food, Drug & Cosmetic Act of 1938. [74] Tincture of opium B.P., containing 1% w/v of anhydrous morphine, also remains in the British Pharmacopoeia, [75] listed as a Class A substance under the Misuse of Drugs Act 1971.
Morphine is the predominant alkaloid found in the cultivated varieties of opium poppy that are used for opium production. [76] Other varieties produce minimal opium or none at all, such as the latex-free Sujata type. Non-opium cultivars that are planted for drug production feature a high level of thebaine or oripavine. Those are refined into drugs like oxycodone. Raw opium contains about 8–14% morphine by dry weight, or more in high-yield cultivars. [23] It may be used directly or chemically modified to produce semi-synthetic opioids such as heroin.
Opium poppies (flower and fruit) appear on the coat of arms of the Royal College of Anaesthetists.
Morphine, formerly also called morphia, is an opiate that is found naturally in opium, a dark brown resin produced by drying the latex of opium poppies. It is mainly used as an analgesic. There are numerous methods used to administer morphine: orally; administered under the tongue; via inhalation; injection into a vein, injection into a muscle, injection under the skin, or injection into the spinal cord area; transdermal; or via administered into the rectal canal suppository. It acts directly on the central nervous system (CNS) to induce analgesia and alter perception and emotional response to pain. Physical and psychological dependence and tolerance may develop with repeated administration. It can be taken for both acute pain and chronic pain and is frequently used for pain from myocardial infarction, kidney stones, and during labor. Its maximum effect is reached after about 20 minutes when administered intravenously and 60 minutes when administered by mouth, while the duration of its effect is 3–7 hours. Long-acting formulations of morphine are sold under the brand names MS Contin and Kadian, among others. Generic long-acting formulations are also available.
Opium is dried latex obtained from the seed capsules of the opium poppy Papaver somniferum. Approximately 12 percent of opium is made up of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade. The latex also contains the closely related opiates codeine and thebaine, and non-analgesic alkaloids such as papaverine and noscapine. The traditional, labor-intensive method of obtaining the latex is to scratch ("score") the immature seed pods (fruits) by hand; the latex leaks out and dries to a sticky yellowish residue that is later scraped off and dehydrated.
Thebaine (paramorphine), also known as codeine methyl enol ether, is an opiate alkaloid, its name coming from the Greek Θῆβαι, Thēbai (Thebes), an ancient city in Upper Egypt. A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but has stimulatory rather than depressant effects. At high doses, it causes convulsions similar to strychnine poisoning. The synthetic enantiomer (+)-thebaine does show analgesic effects apparently mediated through opioid receptors, unlike the inactive natural enantiomer (−)-thebaine. While thebaine is not used therapeutically, it is the main alkaloid extracted from Papaver bracteatum and can be converted industrially into a variety of compounds, including hydrocodone, hydromorphone, oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine, butorphanol and etorphine.
A poppy is a flowering plant in the subfamily Papaveroideae of the family Papaveraceae. Poppies are herbaceous plants, often grown for their colourful flowers. One species of poppy, Papaver somniferum, is the source of the narcotic drug mixture opium, which contains powerful medicinal alkaloids such as morphine and has been used since ancient times as an analgesic and narcotic medicinal and recreational drug. It also produces edible seeds. Following the trench warfare in the poppy fields of Flanders, Belgium, during World War I, poppies have become a symbol of remembrance of soldiers who have died during wartime, especially in the UK, Canada, Australia, New Zealand and other Commonwealth realms.
Papaver rhoeas, with common names including common poppy, corn poppy, corn rose, field poppy, Flanders poppy, red poppy, and Odai, is an annual herbaceous species of flowering plant in the poppy family Papaveraceae. It is native to north Africa and temperate Eurasia and is introduced into temperate areas on all other continents except Antarctica.
Papaver is a genus of 70–100 species of frost-tolerant annuals, biennials, and perennials native to temperate and cold regions of Eurasia, Africa and North America. It is the type genus of the poppy family, Papaveraceae.
The Papaveraceae, informally known as the poppy family, are an economically important family of about 42 genera and approximately 775 known species of flowering plants in the order Ranunculales. The family is cosmopolitan, occurring in temperate and subtropical climates like Eastern Asia as well as California in North America. It is almost unknown in the tropics. Most are herbaceous plants, but a few are shrubs and small trees. The family currently includes two groups that have been considered to be separate families: Fumariaceae and Pteridophyllaceae. Papaver is the classical name for poppy in Latin.
Poppy tea is a herbal tea infusion brewed from poppy straw or seeds of several species of poppy. The species most commonly used for this purpose is Papaver somniferum, which produces opium as a natural defense against predators. In the live flower, opium is released when the surface of the bulb, called the seed pod, is pierced or scraped. For the purpose of the tea, dried pods are more commonly used than the pods of the live flower. The walls of the dried pods contain opiate alkaloids, primarily consisting of morphine and codeine.
Poppy seed is an oilseed obtained from the poppy plant. The tiny, kidney-shaped seeds have been harvested from dried seed pods by various civilizations for thousands of years. It is still widely used in many countries, especially in Central Europe and South Asia, where it is legally grown, used in food products and sold in shops. The seeds are used whole or ground into meal as an ingredient in many foods – especially in pastry and bread – and they are pressed to yield poppyseed oil.
Narcotoline is an opiate alkaloid chemically related to noscapine. It binds to the same receptors in the brain as noscapine to act as an antitussive, and has also been used in tissue culture media.
Papaver bracteatum, also known as the Iranian poppy or Persian poppy and the great scarlet poppy is a sturdy hardy perennial poppy with large deep red flowers up to 8 inches (20 cm) in diameter on stiff stalks up to 4 feet high with a prominent black spot near the base of the petals. It is closely related to the commonly cultivated oriental poppy, Papaver orientale and is sometimes recorded as the varietal form Papaver orientale var. bracteatum.
The Government Opium and Alkaloid Factories (GOAF) is an Indian government-owned organisation. Its headquarter is located in New Delhi. The overall supervision of the organisation comes under the purview of Department of Revenue, Ministry of Finance. There are two factories under this organisation - Government Opium and Alkaloid Works, Ghazipur (U.P.) and Government Opium and Alkaloid Works, Neemuch (M.P.).
Legal cultivation of opium for medicinal purposes is carried out in India, only in selected areas, under free licensing conditions. India is the world's largest manufacturer of legal opium for the pharmaceutical industry according to the CIA World Factbook. India is one among 12 countries in world where legal cultivation for medical use is permissible within the ambit of United Nations, Single Convention on Narcotic Drugs 1961. In India legal cultivation is done primarily in Madhya Pradesh, Rajasthan and Uttar Pradesh. Despite producing poppy for opium production India depends heavily on imports to meet need of Poppy seed for edible purposes and domestic Codeine demand for medical purposes . Opium is heavily imported from its top producing nations like Afghanistan. There is also an account of Opium black marketing in India.
Poppy straw is derived from opium poppies that are harvested when fully mature and dried by mechanical means. Opium poppy straw is what remains after the seed pods have been harvested - that is, the dried stalks, stem and leaves of poppies grown for their seeds. The field-dried leaves, stalk, and seed pod are then used in commercial manufacture of morphine or other poppy-alkaloid derived drugs, by first processing the material, separating the seeds, and then making concentrate of poppy straw where no extraction using the traditional methods of latex extraction has been made. The straw was originally considered an agricultural by-product of the mechanised poppy seed harvest, which was primarily grown for its edible and oil-producing seed. This changed in 1927 when János Kabay developed a chemical process to extract morphine from the crushed capsule. Concentrated poppy straw, consisting mainly of the crushed capsule without the seeds, soon became a valuable source of morphine. Today, concentrate of poppy straw is a major source of many opiates and other alkaloids. It is the source of 90% of the world supply of legal morphine and in some countries it also is a source of illegal morphine, which could be processed into illegal heroin.
An opiate is an alkaloid substance derived from opium. It differs from the similar term opioid in that the latter is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain. Opiates are alkaloid compounds naturally found in the opium poppy plant Papaver somniferum. The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. Opiates have long been used for a variety of medical conditions, with evidence of opiate trade and use for pain relief as early as the eighth century AD. Most opiates are considered drugs with moderate to high abuse potential and are listed on various "Substance-Control Schedules" under the Uniform Controlled Substances Act of the United States of America.
Peronospora arborescens is a plant pathogen. It causes downy mildew on leaves of Papaver spp. It has economic importance on Papaver somniferum grown as an oilseed crop, for example in central and eastern Europe. It is controlled by sanitation, crop rotation, use of clean seed and fungicide sprays of the foliage. There are other species of Peronospora which occur on Papaver: Peronospora argemones (Gäum.), Peronospora cristata (Tranzschel), and Peronospora papaveris-pilosi (Vienn.-Bourg.).
Papaver setigerum, common name poppy of Troy or dwarf breadseed poppy, is a herbaceous annual plant of the family Papaveraceae.
Narceine is an opium alkaloid produced by the Papaver somniferum plant. It is a bitter, crystalline compound with narcotic effects. It was formerly used as a substitute for morphine. Its name is derived from the Greek νάρκη (nárkē), meaning numbness, and the postfix -ine referring to an alkaloid.
Salutaridinol is a modified benzyltetrahydroisoquinoline alkaloid with the formula C19H23NO4. It is produced in the secondary metabolism of the opium poppy Papaver somniferum (Papaveraceae) as an intermediate in the biosynthetic pathway that generates morphine. As an isoquinoline alkaloid, it is fundamentally derived from tyrosine as part of the shikimate pathway of secondary metabolism. Salutaridinol is a product of the enzyme salutaridine: NADPH 7-oxidoreductase and the substrate for the enzyme salutaridinol 7-O-acetyltransferase, which are two of the four enzymes in the morphine biosynthesis pathway that generates morphine from (R)-reticuline. Salutaridinol's unique position adjacent to two of the four enzymes in the morphine biosynthesis pathway gives it an important role in enzymatic, genetic, and synthetic biology studies of morphine biosynthesis. Salutaridinol levels are indicative of the flux through the morphine biosynthesis pathway and the efficacy of both salutaridine: NADPH 7-oxidoreductase and salutaridinol 7-O-acetyltransferase.
Isoquinoline alkaloids are natural products of the group of alkaloids, which are chemically derived from isoquinoline. They form the largest group among the alkaloids.
