摘要：

Two new lupane triterpenes, salacianone (lup-20(29)-en-3,21-dione) and salacianol (21 beta-hydroxylup-20(29)-en-3-one), have been isolated from the hexane extract of the stem bark of Salacia beddomei together with the known compounds lup-20(29)-en-3-one, friedelan-3-one, 15 alpha-hydroxyfriedelan-3-one, 15 alpha-hydroxyfriedelane-1,3-dione, pristimerin and sitosterol. Their structures have been elucidated with the aid of IR, NMR and mass spectroscopic techniques.
