Lysergamide
Ergine is an alkaloid of the ergoline family. Like other ergoline alkaloids, it occurs in various species of vines of the Convolvulaceae (morning glory) family and in some species of lower fungi. As the dominant alkaloid in the hallucinogenic seeds of Rivea corymbosa, Argyreia nervosa (Hawaiian baby woodrose) and Ipomoea tricolor (morning glory), it is often stated that ergine and/or isoergine (its epimer) is responsible for the psychedelic activity, though this has not been proven. Long term exposure to some ergoline alkaloids can cause ergotism, a disease causing convulsive and gangrenous symptoms. (L1918, L1919)
