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.

Contents

Alkaloids

Ipomoea tricolor seeds contains LSA and LSH among other alkaloids due to the presence of a symbiotic fungus Periglandula ipomoeae , which produces them. [2]

Description

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 (122+12 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.

Cultivation and uses

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]

Weed control

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]

Chemical deterrent used to discourage ingestion

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.

Colour change

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.

<span class="mw-page-title-main">Ergine</span> Chemical compound

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.

<span class="mw-page-title-main">Ergoline</span> Chemical compound

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.

<i>Ipomoea</i> Genus of flowering plants

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.

<i>Argyreia nervosa</i> Species of plant

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.

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.

<span class="mw-page-title-main">Lysergol</span> Chemical compound

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.

The amino acid tryptophan is the biochemical precursor of indole alkaloids.

<i>Ipomoea hederacea</i> Species of flowering plant

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.

<i>Ipomoea asarifolia</i> Species of flowering plant

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.

    “Clavines are thought to contribute substantially to convulsive ergotism, since C. fusiformis ergots, which possess clavines, but no 1 or lysergyl amides, cause convulsive symptoms (26). However, the ergopeptines are known to produce similar symptoms, and are also thought to cause gangrenous ergotism (6). The occurrence of convulsive ergotism without dry gangrene suggests that other clavine or lysergyl alkaloids are involved, or that individual effects of specific ergopeptines may give clinically different syndromes (6).”

    “It has been suggested6 that the insecticide coating on the morning glory seed might be promoting adverse side effects that have been noted. The majority of commercial seeds are treated with N-tri-chlorete which is a fungicide and seed protectant having a tolerance of 100 parts per million.8 Thus, this is quite an inocuous product from the toxicologic point of view and would require ingestion of quantities beyond the capacity of the stomach to absorb, in amounts found as a seed coater, to be considered lethal.9 Symptoms involving the nervous system would be lacking if we were dealing only with the effects of this fungicide. Formerly, compounds containing mercury were used extensively as fungicides and there is the possibility that some seeds so treated might pose a toxicologic danger if ingested. This is considered unlikely as the newer seed protectants have been in use for a considerably longer period than the current morning glory fad.”
    “It would seem then, that both the psychological and physiological effects observed in the ingestion of the seed of the morning glory reside in the alkaloids of the seed and not the seed protectant. The LSD-like reaction is most likely due to the LSD-like alkaloids for no pure LSD has as yet been isolated from the seed. As all compounds occurring in the morning glory seed have not been studied intensively enough to inspire confidence in their respective roles, they cannot yet be considered for scientific experimental use much less be used irresponsibly in excitement-seeking self-experimentation.” (Comment, p. 1134)
