A new ent-kaurene beta-D-glucoside was isolated from Rabdosia rubescens, together with the known compounds oridonin, ponicidin, and pedalitin. The structure of new compound was determined, on the basis of spectral data and X-ray crystallographic analysis, to be ent-7 beta,20-epoxy-kaur-16-ene-1 beta,6 alpha,7 alpha,14 alpha,15 alpha-pentanol 1-O-beta-D-glucopyranoside.
从冬凌草中分离出一种新的对映-贝壳杉烯β-D-葡萄糖苷，以及已知化合物冬凌草甲素、ponicidin和pedalitin。基于光谱数据和X射线晶体学分析确定新化合物的结构为对映-7β,20-环氧-贝壳杉-16-烯-1β,6α,7α,14α,15α-戊醇1-O-β-D-吡喃葡萄糖苷。
