Abstract

Hirsutine, hirsuteine, rhynchophylline, isorhynchophylline, rotundifoline, isorotundifoline, mitraphylline, isomitraphylline, rhynchophylline N–oxide and anti rotundifoline N–oxide have been isolated from Mitragyna rubrostipulata (Schum.) Havil. All were present in the root bark but hirsutine and hirsuteine were not found in the leaves or stem bark. Comparative studies have been made of the distribution of these same alkaloids in related species of Mitragyna.
