Abstract

From the chloroform extract of the stem bark of Erythrophleum suaveolens (Guill. & Perr.) Brenan, a new diterpenic alkaloid (Erythrosuavine) has been isolated and characterized as N-acetyl-9,11-dehydro-6-ketocassaidinyl-3-acetate 1. The structure of the above compound was elucidated from one and two-dimensional 1H and 13C NMR spectra as well as from 1H-1H COSY, HMQC and HMBC correlations.
