摘要：
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.
