Abstract

Three new cadinane- and guaiane-type sesquiterpenoids, 2-hydroxy-10-epi-zonarene 1, 2, 15-dihydroxycalamenene 2 and guaia-4, 6-dien-3-one 3, were isolated from the wood of Enterospermum madagascariensis (Rubiaceae) grown in Madagascar. Their structures were established from concerted application of 2D NMR techniques including gs-COSY, gs-HMQC, gs-HMBC and NOESY.

摘要

从生长在马达加斯加的马达加斯加肠籽木（茜草科）木材中分离出三种新的杜松烷型和愈创木烷型倍半萜，2-羟基-10-表-蛇床烯1、2,15-二羟基菖蒲烯2和愈创木-4,6-二烯-3-酮3。它们的结构通过二维核磁共振技术（包括gs-COSY、gs-HMQC、gs-HMBC和NOESY）的协同应用得以确定。
