New Dammarane-Type Acetylated Triterpenoids and Their Related Compounds of Ficus pumila Fruit

Abstract

From the methanolic extract of Ficus pumila LINN. fruit (Moraceae), two new acetylated dammarane-type triterpenoids (3, 4) and their two new related compounds (1, 2) were obtained, and their structures were determined by spectral methods as 3β-acetoxy-22, 23, 24, 25, 26, 27-hexanordammaran-20-one (1), 3β-acetoxy-20, 21, 22, 23, 24, 25, 26, 27-octanordammaran-17β-ol (2), 3β-acetoxy-(20R, 22E, 24RS)-20, 24-dimethoxydammaran-22-en-25-ol (3) and 3β-acetoxy-(20S, 22E, 24RS)-20, 24-dimethoxydammaran-22-en-25-ol (4).
