摘要：

From the Me2CO extract of the whole plant of Euphorbia boetica a new tetracyclic diterpene was isolated. Its structure was established based on NMR spectroscopic data obtained using a combination of one- and two-dimensional techniques. The known steroids 5 alpha-stigmastane-3 beta-6 alpha-diol, 5 alpha-stigmastane-3 beta-5,6 beta-triol and beta-sitosterol glucopyranoside were also isolated. (C) 1999 Elsevier Science Ltd.
