摘要：

Two new lupane triterpenoids, 20,29-epoxysalacianone (20,29-epoxylupane-3,21-dione) and 6 beta-hydroxysalacianone [6 beta-hydroxylup-20(29)-ene-3,21-dione] have been isolated from the hexane and ethyl acetate extracts of the stem bark of Salacia beddomei, together with the known compounds 3 beta,28-dihydroxylup-20(29)-ene (betulin) and 2 alpha,3 beta dihydroxylup-20(29)-ene. Their structures have been elucidated with the help of NMR and mass spectroscopic techniques.
