从大戟科小狼毒Euphorbiaprolifera根的乙醇提取物中分得5个三萜化合物, 经光谱鉴定, 其中4个为已知的环菠萝蜜烷型三萜:环劳顿醇(cyclolaudenol, Ⅲ), 3-酮基-环劳顿甾(3-ketocyclolaudane, Ⅳ), 24-甲烯基-环优卡里醇(24-methylene-cycloeucalenol, Ⅴ), 3, 25-二羟基-23-环安坦烯(23-cycloartene-3, 25-diol, Ⅵ);另一个为新的麦角甾醇型三萜:3β-羟基-24-甲基-5, 14, 26-麦角甾烯(24-methyl-5, 14, 26-ergostatrien-3β-ol, Ⅶ)。

[Abstract]
Five triterpenes have been isolated from ethanol extracts of the roots of Euphorbia prolifera Buch-Hom. Their structures have been identified by spectral methods as: 24-umethyl-9, 19-cyclolanost-25-en3β-ol (Ⅲ), 24-methyl-9, 19-cyclolanost-25-en-3-one (Ⅳ), 24-methylene-cycloeucalenol (Ⅴ), 23-cycloartene-3,25-diol (Ⅵ), and 24-methyl-5, 14, 26-ergostatrien-3β-ol (Ⅶ). Compound Ⅶ is a new ergosterol type triterpene.
