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).
