Ergine, also known as d-lysergic acid amide (LSA), d-lysergamide, and LA-111, is an alkaloid of the ergoline family that occurs in various species of vines of the Convolvulaceae and some species of fungi. As the dominant alkaloid in the hallucinogenic seeds of Rivea corymbosa (ololiuhqui), Argyreia nervosa (Hawaiian baby woodrose) and Ipomoea tricolor (morning glories, tlitliltzin), it is often stated that ergine and/or isoergine (its epimer) is responsible for the psychedelic activity. In fact, the effects of synthetic LSA and iso-LSA are not particularly psychedelic, see Mixing the Kykeon below for a summary of human trials, and Chapter 17 and entry #26 of TiHKAL for further discussion. As a precursor to LSD, ergine is a DEA schedule III drug in the United States and a Class A drug in the UK.

History

A traditional use of morning glory seeds by Mexican Native Americans was first described by Richard Schultes in 1941 in a short report documenting their use going back to Aztec times (cited in TiHKAL by Alexander Shulgin). Further research was published in 1960, when Don Thomes MacDougall reported that the seeds of Ipomoea tricolor were used as sacraments by certain Zapotecs, sometimes in conjunction with the seeds of Rivea corymbosa, another species which has a similar chemical composition, with lysergol instead of ergometrine. Ergine was assayed for human activity by Albert Hofmann in self-trials in 1947, well before it was known to be a natural compound. Intramuscular administration of a 500 microgram dose led to a tired, dreamy state, with an inability to maintain clear thoughts. After a short period of sleep the effects were gone, and normal baseline was recovered within five hours.[2]

In 1956 the Central Intelligence Agency conducted research on the psychedelic properties of the ergine in the seeds of Rivea corymbosa, as Subproject 22 of MKULTRA.

Shamanic stories say ipomoea purpurea seeds, when swallowed or chewed, may incite a mild trip where synesthesia occurs and eye imagery is enhanced.[3]


Natural occurrence

Ergine has been found in high concentrations of 20 µg/g dry weight in the grass Stipa robusta (sleepygrass) infected with an Acremonium endophytic fungus together with other ergot alkaloids.[4]

It is also found in the seeds of several varieties of Morning Glories in concentrations of approximately 10 µg per seed, as well as Hawaiian Baby Woodrose seeds, at a concentration of around .3%.

Extraction

LSA can be extracted from morning glory (Ipomoea spp.) seeds[5] or Hawaiian baby woodrose.[6]
