摘要
Three novel triterpenoids, 3beta-acetoxy-11alpha-hydroxy-11(12-->13)abeooleanan-12-al (1), 3beta-hydroxy-20-oxo-29(20-->19)abeolupane (2), and 29,30-dinor-3beta-acetoxy-18,19-dioxo-18,19-secolupane (3), and the known 4, 5a, and 5b were isolated from the aerial roots of Ficus microcarpa. Their structures were elucidated on the basis of 2D NMR and X-ray diffraction experiments. Compound 1, derived from the oleanane skeleton, has an unusual five-membered C ring. Compounds 2 and 3, derived from the lupane skeleton, have unique skeletons that may arise from the same biogenetic pathway.
