Lysergol, is an alkaloid of the ergoline family that occurs in various species of vines of the Convolvulaceae and some species of fungi. As the minor alkaloid in the hallucinogenic seeds of Rivea corymbosa (ololiuhqui), Argyreia nervosa (Hawaiian baby woodrose) and Ipomoea violacea (tlitliltzin).
Lysergol is uncontrolled in the USA, but possession and sale may be illegal under the Federal Analog Act because of its relationship to LSD and ergine, which are controlled substances.
A series of simple O-acylated derivatives of the naturally occurring clavine alkaloids lysergol and dihydrolysergol-I were synthesized and tested in-vitro for their ability to interact with 5-HT2A receptors in rat tail artery, 5-HT2C receptors in piglet choroid plexus, 5-HT1B receptors in guinea-pig iliac artery and alpha1-adrenergic receptors in rat aorta.
