harmine
Also known as 7-methoxy-1-methyl-9H-beta-carboline, 6-methoxyharman, yageine, banisterine, yajeine, leucoharmine, telepathine
Harmine, also known as banisterine or telepathine, as well as 7-methoxyharman or 7-methoxy-1-methyl-β-carboline, is a β-carboline and a harmala alkaloid which has hallucinogenic effects and monoamine oxidase inhibitor (MAOI) activity. It occurs in a number of different plants, most notably Peganum harmala and Banisteriopsis caapi. Harmine reversibly inhibits monoamine oxidase A (MAO-A), an enzyme which breaks down monoamines, making it a reversible inhibitor of monoamine oxidase A (RIMA). Harmine does not inhibit MAO-B.

Harmine, also known as banisterine or telepathine, as well as 7-methoxyharman or 7-methoxy-1-methyl-β-carboline, is a β-carboline and a harmala alkaloid which has hallucinogenic effects and monoamine oxidase inhibitor (MAOI) activity.

Harmine reversibly inhibits monoamine oxidase A (MAO-A), an enzyme which breaks down monoamines, making it a reversible inhibitor of monoamine oxidase A (RIMA). Harmine does not inhibit MAO-B.
Harmine is found in various plants—including tobacco, Passiflora species, lemon balm, and several Banisteriopsis species—as well as in some butterflies of the Nymphalidae family. It was first isolated and named by German chemist Julius Fritzsche in 1847 from Peganum harmala seeds, later identified in Banisteriopsis caapi under various names, with its structure determined in 1927.
