Abstract

Two new diterpenoids, forskolins I and J, have been isolated in our further investigation on Coleus forskohlii (Willd.) Briq. collected in Yunnan Province. Their structures have been determined as 1alpha,6beta-diacetoxy-7beta,9alpha-dihydroxy-8,13-epoxylabd-14-en-11-one (1) and 1alpha,9alpha-dihydroxy-6beta,7beta-diacetoxy-8,13-epoxylabd-14-en-11-one (2) by spectral methods (including 1D and 2D NMR techniques).

摘要

在我们对采自云南省的毛喉鞘蕊花（Coleus forskohlii (Willd.) Briq.）进行的进一步研究中，分离出了两种新的二萜类化合物，毛喉素I和毛喉素J。通过光谱方法（包括一维和二维核磁共振技术）确定它们的结构分别为1α,6β - 二乙酰氧基 - 7β,9α - 二羟基 - 8,13 - 环氧 - 赖百当 - 14 - 烯 - 11 - 酮（1）和1α,9α - 二羟基 - 6β,7β - 二乙酰氧基 - 8,13 - 环氧 - 赖百当 - 14 - 烯 - 11 - 酮（2）。
