Abstract

One icetexane and two abietane diterpenes were isolated from the aerial parts of Salvia gilliesii, and characterized as 5-epi-icetexone; 12-hydroxy-11,14-diketo-6,8,12-abietatrien-19,20-olide and 6 alpha,12,19-trihydroxy-11,14-diketo-8,12-abietadien-20,7 beta-olide, respectively. The structures were established by analysis of their 1H and 13C NMR spectra with the aid of 2D experiments. The triterpene oleanolic acid was isolated from the same source.

摘要

从吉利鼠尾草地上部分分离得到一种紫杉烷型二萜和两种松香烷型二萜，分别鉴定为5-表紫杉酮；12-羟基-11,14-二酮-6,8,12-松香三烯-19,20-内酯和6α,12,19-三羟基-11,14-二酮-8,12-松香二烯-20,7β-内酯。通过1H和13C NMR光谱分析并借助二维实验确定了其结构。从同一来源分离得到了三萜齐墩果酸。
