Ipomoea tricolor | |
Ipomoea tricolor, the Mexican morning glory or just morning glory, [1] is a species of flowering plant in the family Convolvulaceae, native to the tropics of the Americas, and widely cultivated and naturalised elsewhere.
Ipomoea tricolor seeds contains LSA and LSH among other alkaloids due to the presence of a symbiotic fungus Periglandula ipomoeae , which produces them. [2]
It is an herbaceous annual or perennial twining liana growing to 2–4 m (7–13 ft) tall. The leaves are spirally arranged, 3–7 cm (1–3 in) long with a 1.5–6 cm (1⁄2–2+1⁄2 in) long petiole. The flowers are trumpet-shaped, 4–9 cm (2–4 in) in diameter, most commonly blue with a white to golden yellow centre.
I. tricolor and many rarer species of morning glory, contain ergoline alkaloids, predominantly ergine. Some supermarkets have stopped carrying I. tricolor seeds because of this.
In cultivation, the species is very commonly grown misnamed as Ipomoea violacea , actually a different, though related, species. [3] [4] I. tricolor does not tolerate temperatures below 5 °C (41 °F), and so in temperate regions is usually grown as an annual. It is in any case a relatively short-lived plant. It prefers a warm, sheltered, sunny position such as a south- or west-facing wall.
Ingesting any part of the plant may cause discomfort. [5]
Numerous cultivars of I. tricolor with different flower colours have been selected for use as ornamental plants; widely grown examples include:
The cultivar 'Heavenly Blue' has gained the Royal Horticultural Society's Award of Garden Merit. [5] [6]
Ipomoea tricolor has phytotoxic effects which inhibit seedling growth in weeds. In Mexico, farmers promote the growth of I. tricolor as a cover plant. It prevents weeds and unwanted plants from growing. When it is time to plant crops, this plant is incorporated into the soil. Although it is toxic to weeds, it does not affect crops such as sugarcane. [7]
It is rumored that I. tricolor seeds are coated with a chemical that induces sickness so as to dissuade people from using them as a drug, but this is probably a rumor that stems from several factors:
- I. tricolor seeds, by themselves, induce sickness as a result of glycoresins [8] [9] and the very ergolines that are desired by users. [10]
- Such is done to other commonly available substances that can induce effects, specifically compressed air and acetone (which have bitterant added) and denatured alcohol.
- Chemical coatings are added to garden seeds to prevent fungal growth (e.g. neonicotinoids, Thiram, and ApronMaxx®).
- Packets of I. tricolor seeds are known to have a warning that the seeds are toxic.
Methyl mercury type compounds have been specified in the rumors, but a 1964 article conveys that such compounds were only used in the past and that the majority "insecticide" at the time of publication was "quite an innocuous substance." [11] There's no evidence that the seeds are coated with a chemical deterrent.
In Ipomoea tricolor 'Heavenly Blue', the colour of the flower changes during blossom according to an increase in vacuolar pH. [12] [13] [14] This shift, from red to blue, is induced by chemical modifications affecting the anthocyanin molecules present in the petals.
Convolvulaceae, commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato.
Ipomoea corymbosa is a species of morning glory, native throughout Latin America from Mexico as far south as Peru and widely naturalised elsewhere. Its common names include Christmasvine, Christmaspops, and snakeplant.
Ergot or ergot fungi refers to a group of fungi of the genus Claviceps.
Ergotism is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus—from the Latin clava "club" or clavus "nail" and -ceps for "head", i.e. the purple club-headed fungus—that infects rye and other cereals, and more recently by the action of a number of ergoline-based drugs. It is also known as ergotoxicosis, ergot poisoning, and Saint Anthony's fire.
Morning glory is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are:
Ergine, also known as lysergic acid amide and lysergamide, is an ergoline alkaloid that occurs in Clavicipitaceous fungi, which includes Convolvulaceae vines, which have a permanent bond with these fungi. The most common source of ergine for consumers is the seeds of Ipomoea tricolor, Ipomoea corymbosa, and Argyreia nervosa; isoergine and lysergic acid propanolamide have also been shown to contribute to their psychoactivity.
Ergoline is a core structure in many alkaloids and their synthetic derivatives. Ergoline alkaloids were first characterized in ergot. Some of these are implicated in the condition of ergotism, which can take a convulsive form or a gangrenous form. Even so, many ergoline alkaloids have been found to be clinically useful. Annual world production of ergot alkaloids has been estimated at 5,000–8,000 kg of all ergopeptines and 10,000–15,000 kg of lysergic acid, used primarily in the manufacture of semi-synthetic derivatives.
Lysergic acid, also known as D-lysergic acid and (+)-lysergic acid, is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and found in the seeds of Argyreia nervosa, and Ipomoea species.
Ipomoea is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or water spinach, sweet potato, bindweed, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining climbing plants.
Argyreia nervosa is a perennial climbing vine native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Though it can be invasive, it is often prized for its aesthetic and medicinal value. Common names include Hawaiian baby woodrose, adhoguda अधोगुडा or vidhara विधारा (Sanskrit), elephant creeper and woolly morning glory. Its seeds are known for their powerful entheogenic properties, greater or similar to those of Ipomoea species, with users reporting significant psychedelic and spiritual experiences. The two botanical varieties are Argyreia nervosa var. nervosa described here, and Argyreia nervosa var. speciosa, the roots of which are used in Ayurvedic medicine.
Ergonovine, also known as ergometrine and lysergic acid propanolamide is a medication used to cause contractions of the uterus to treat heavy vaginal bleeding after childbirth. It can be used either by mouth, by injection into a muscle, or injection into a vein. It begins working within 15 minutes when taken by mouth and is faster in onset when used by injection. Effects last between 45 and 180 minutes.
Ipomoea purpurea, the common morning-glory, tall morning-glory, or purple morning glory, is a species in the genus Ipomoea, native to Mexico and Central America.
ᴅ-Lysergic acid α-hydroxyethylamide, also known as ᴅ-lysergic acid methyl carbinolamide, is an ergoamide and an ergoline. It is perhaps the main constituent of the parasitic fungus, Claviceps paspali; and found in trace amounts in Claviceps Purpurea. C. paspali and C. purpurea are ergot-spreading fungi. Periglandula, Clavicipitacepus fungi, are permanently symbiotically connected to an estimated 450 species of Convolvulaceae and thus generate LAH in some of them. The most well-known ones are Ipomoea tricolor, Turbina corymbosa (coaxihuitl), and Argyreia nervosa.
Lysergol is an alkaloid of the ergoline family that occurs as a minor constituent in some species of fungi, and in the morning glory family of plants (Convolvulaceae), including the hallucinogenic seeds of Rivea corymbosa (ololiuhqui), Argyreia nervosa and Ipomoea violacea. Lysergol is not a controlled substance in the USA. Its possession and sale is also legal under the U.S. Federal Analog Act because it does not have a known pharmacological action or a precursor relationship to LSD, which is a controlled substance. However, lysergol is an intermediate in the manufacture of some ergoloid medicines.
Ipomoea violacea is a perennial species of Ipomoea that occurs throughout the world with the exception of the European continent. It is most commonly called beach moonflower or sea moonflower as the flowers open at night.
Indole alkaloids are a class of alkaloids containing a structural moiety of indole; many indole alkaloids also include isoprene groups and are thus called terpene indole or secologanin tryptamine alkaloids. Containing more than 4100 known different compounds, it is one of the largest classes of alkaloids. Many of them possess significant physiological activity and some of them are used in medicine. The amino acid tryptophan is the biochemical precursor of indole alkaloids.
Ipomoea hederacea, the ivy-leaved morning glory or Kaladana, is a flowering plant in the bindweed family. The species is native to tropical parts of the Americas, and has more recently been introduced to North America. It now occurs there from Arizona to Florida and north to Ontario and North Dakota. Like most members of the family, it is a climbing vine with alternate leaves on twining stems. The flowers are blue to rose-purple with a white inner throat and emerge in summer and continue until late fall. The leaves are typically three-lobed, but sometimes may be five-lobed or entire. Flowers occur in clusters of one to three and are 2.5–4.5 cm long and wide. The sepals taper to long, recurved tips and measure 12–24 mm long. The species shares some features with the close relative Ipomoea purpurea, and is almost identical in appearance to wild forms of I. nil.
Ipomoea asarifolia, known as the ginger-leaf morning-glory, is a species of plant in the family Convolvulaceae, of the genus Ipomoea.
The consumption of hallucinogenic plants as entheogens goes back to thousands of years. Psychoactive plants contain hallucinogenic particles that provoke an altered state of consciousness, which are known to have been used during spiritual rituals among cultures such as the Aztec, the Maya, and Inca. The Maya are indigenous people of Mexico and Central America that had significant access to hallucinogenic substances. Archaeological, ethnohistorical, and ethnographic data show that Mesoamerican cultures used psychedelic substances in therapeutic and religious rituals. The consumption of many of these substances dates back to the Olmec era ; however, Mayan religious texts reveal more information about the Aztec and Mayan civilization. These substances are considered entheogens because they were used to communicate with divine powers. "Entheogen," an alternative term for hallucinogen or psychedelic drug, derived from ancient Greek words ἔνθεος and γενέσθαι. This neologism was coined in 1979 by a group of ethnobotanists and scholars of mythology. Some authors claim entheogens have been used by priests throughout history, with appearances in prehistoric cave art such as a cave painting at Tassili n'Ajjer, Algeria that dates to roughly 8000 BP. Shamans in Mesoamerica served to diagnose the cause of illness by seeking wisdom through a transformational experience by consuming drugs to learn the crisis of the illness
Periglandula are a genus of fungi in the family Clavicipitaceae. They live as epibionts, in a symbiotic relationship with two species of plant, Ipomoea asarifolia and Ipomoea corymbosa. They are known to produce ergot alkaloids related to lysergic acid.
