An investigation of the fresh leaves of Mitragyna speciosa has resulted in the isolation of a new alkaloid in addition to the indole alkaloids previously reported The new alkaloid is the 3-dehydro derivative of mitragynine and its structure was
- 7-hydroxy-mitragynine - Drugs-Forum
7-hydroxy-mitragynine is a strong drug found in kratom It is stronger than morphine, but it is found in very small amounts in kratom Mitagynine is found in much higher amounts in the plant
