摘要：

Six new triterpenes, 3 beta -acetoxy-12 beta ,13 beta -epoxy-11 alpha -hydroperoxyursane (1), 3 beta -acetoxy-11 alpha -hydroperoxy-13 alphaH-ursan-12-one (2), 3 beta -acetoxy-1 beta ,11 alpha -epidioxy-12-ursene (3), (20S)-3 beta -acetoxylupan-29-oic acid (4), (20S)-3 beta -acetoxy-20-hydroperoxy-30-norlupane (5), and 3 beta -acetoxy-18 alpha -hydroperoxy-12-oleanen-11-one (6), together with 3 beta -acetoxy-12-oleanen-11-one (7), were isolated from the aerial roots of Ficus microcarpa. Compounds 1-3, 5, and 6 were characterized as new peroxytriterpenes. The structures of 3 and 6 were confirmed by X-ray crystallography, and their structures were elucidated by spectroscopic and chemical methods.
