Two novel steroids, 3beta,7alpha-dihydroxy-4alpha,14alpha-dimethyl-5alpha-cholest-8-en-11-one (2) and 3beta,7beta-dihydroxy-4alpha,14alpha-dimethyl-5alpha-cholest-8-en-11-one (3) were isolated from the latex of Euphorbia officinarum. Their structures were established on the basis of NMR and MS studies.
从药用大戟的乳胶中分离出两种新型甾体化合物，即3β,7α - 二羟基 - 4α,14α - 二甲基 - 5α - 胆甾 - 8 - 烯 - 11 - 酮（2）和3β,7β - 二羟基 - 4α,14α - 二甲基 - 5α - 胆甾 - 8 - 烯 - 11 - 酮（3）。它们的结构是通过核磁共振（NMR）和质谱（MS）研究确定的。
