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.
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.
Papaver somniferum, commonly known as the opium poppy or breadseed poppy, 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.
Papaverine is an opium alkaloid antispasmodic drug, used primarily in the treatment of visceral spasms and vasospasms, occasionally in the treatment of erectile dysfunction and acute mesenteric ischemia. While it is found in the opium poppy, papaverine differs in both structure and pharmacological action from the analgesic morphine and its derivatives.
Noscapine, also known as narcotine, nectodon, nospen, anarcotine and (archaic) opiane, is a benzylisoquinoline alkaloid of the phthalideisoquinoline structural subgroup, which has been isolated from numerous species of the family Papaveraceae. It lacks effects associated with opioids such as sedation, euphoria, or analgesia (pain-relief) and lacks addictive potential. Noscapine is primarily used for its antitussive (cough-suppressing) effects.
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.
Scoulerine, also known as discretamine and aequaline, is a benzylisoquinoline alkaloid (BIA) that is derived directly from (S)-reticuline through the action of berberine bridge enzyme. It is a precursor of other BIAs, notably berberine, noscapine, (S)-tetrahydropalmatine, and (S)-stylopine, as well as the alkaloids protopine, and sanguinarine. It is found in many plants, including opium poppy, Croton flavens, and certain plants in the genus Erythrina.
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.
Laudanosine or N-methyltetrahydropapaverine is a recognized metabolite of atracurium and cisatracurium. Laudanosine decreases the seizure threshold, and thus it can induce seizures if present at sufficient threshold concentrations; however such concentrations are unlikely to be produced consequent to chemodegradable metabolism of clinically administered doses of cisatracurium or atracurium.
Meconic acid, also known as acidum meconicum and poppy acid, is a chemical substance found in certain plants of the poppy family, Papaveraceae, such as Papaver somniferum and Papaver bracteatum. Meconic acid constitutes about 5% of opium and can be used as an analytical marker for the presence of opium. Meconic acid has erroneously been described as a mild narcotic, but it has little or no physiological activity, and is not used medicinally. Meconic acid forms salts with alkaloids and metals. These salts as well as meconic acid esters are called meconates. Meconic acid was first isolated by Friedrich Sertürner in 1805.
(S)-Canadine, also known as (S)-tetrahydroberberine and xanthopuccine, is a benzylisoquinoline alkaloid (BIA), of the protoberberine structural subgroup, and is present in many plants from the family Papaveraceae, such as Corydalis yanhusuo and C. turtschaninovii.
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.
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.
Papaver somniferum × Papaver bracteatum, also known as Sagan's poppy is a hybrid between the opium poppy and the Iranian poppy.
Isoquinoline alkaloids are natural products of the group of alkaloids, which are chemically derived from isoquinoline. They form the largest group among the alkaloids.
