Chemical constituents from the bark of Anisopus mannii

Research output: Contribution to journalArticle

Abstract

A minor novel 1,7-naphthyridine alkaloid with an unprecedented skeleton, named anisopusine (1), was isolated from the CH2Cl2 soluble materials of an acetone extract of the bark of Anisopus mannii (Asclepiadaceae) together with four known compounds 5 alpha-hydroxy-lup-20(29)-en-3 beta-yl eicosanoate (2), [6]-gingerdione (3), [6]-dehydrogingerdione (4), and ferulic acid (5). Their structures were determined on the basis of spectroscopic data, including 1D and 2D NMR, HR-EI-MS. Compounds (2-5) were characterized for the first time from this genus.
