摘要：

Boeticol [1], a new tetracyclic triterpene, was isolated from the acetone extract of Euphorbia boetica. Its structure was established as 19(10-->9)-abeo-8 alpha,9 beta,10 alpha-eupha-5,24-dien-3 beta-ol, based on nmr spectroscopic data obtained using a combination of one- and two-dimensional techniques. The known triterpene euphol was also isolated.
