Kratom Chemistry

More than 25 alkaloids have been isolated in Mitragyna speciosa. The three most abundant indoles are mitragynine (responsible for 1/2 of the alkaloid content), paynanthine, and speciogynine. The first two of these are believed to be unique to M. speciosa. The two most abundant oxindoles are mitraphylline and speciofoline. Other alkaloids present include ajmalicine, corynanthedine, mitraversine, rhychophylline, and stipulatine. Mitragynine is believed by many to be, but has not been proven to be, the primary active alkaloid in M. speciosa.
