麦角醇

Lysergol is an alkaloid of the ergoline family that occurs as a minor constituent in some species of fungi (most within Claviceps), and in the morning glory family of plants (Convolvulaceae), including the hallucinogenic seeds of Rivea corymbosa (ololiuhqui), Argyreia nervosa (Hawaiian baby woodrose) 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 of it does not have a known pharmacological action or a precursor relationship to LSD, which is a controlled substance. However, lysergol can be utilized as an intermediate in the manufacture of some ergoloid medicines (e.g. nicergoline).
