四种新的羊毛甾烷三萜类化合物，即(3 ss)-3-羟基-24-亚甲基羊毛甾-8-烯-7,11-二酮(1)、(3 ss)-3-羟基羊毛甾烷-8,24-二烯-7,11-二酮(2)、(3 ss,7 α)-3,7-二羟基羊毛甾-8,24-dien-11-一(3)、和(3 ss,11 ss)-3,11-二羟基lanosta-8,24-dien-7-one (4) 与2 种已知化合物一起从Euphorbia humifusa 中分离出来。在广泛的光谱分析和与相关已知化合物的比较的基础上，阐明了这些新化合物的结构。
Four new lanostane triterpenoids, namely (3 ss)-3-hydroxy-24-methylenelanost-8-ene-7,11-dione (1), (3 ss)-3-hydroxylanosta-8,24-diene-7,11-dione (2), (3 ss,7 alpha)-3,7-dihydroxylanosta-8,24-dien-11-one (3), and (3 ss,11 ss)-3,11-dihydroxylanosta-8,24-dien-7-one (4) were isolated from Euphorbia humifusa, together with 2 known compounds. The structures of these new compounds were elucidated on the basis of extensive spectroscopic analysis and comparison with the related known compounds.
