A New Degraded Sesquiterpene from the Twigs of Trigonostemon Lutescens

Abstract

A new degraded sesquiterpene, tectoionol C (1), together with five known compounds wilsonol F (2), heterodendrin (3), epi-heterodendrin (4), 7-deoxogeayine (5), and 1H-indole-3-carboxylicacid, methyl ester (6), was isolated from the twigs of Trigonostemon lutescens. Their structures were determined by spectroscopic methods including 1D and 2D NMR techniques, as well as by comparison with published data.
