Conodurine, conoduramine, and ervahanine derivatives from Tabernaemontana corymbosa

Phytochemistry. 2003 Jul;63(5):625-9. doi: 10.1016/s0031-9422(03)00087-6.

Abstract

Four bisindole alkaloids, viz., 19'(S)-hydroxyconodurine, conodurinine, 19'(S)-hydroxyconoduramine, and 19'(S)-hydroxyervahanine A, in addition to conodurine and ervahanine A, were obtained from the leaf and stem-bark extracts of Tabernaemontana corymbosa. The structures of the new alkaloids were determined using NMR and MS analysis.
