Abstract

Five new taraxastane-type triterpenes, 22-oxo-20-taraxasten-3β-ol (1), 20(30)-taraxastene-3β, 21α-diol (2), 20α, 21α-epoxytaraxastan-3β-ol (3), 20-taraxastene-3β, 22β-diol (4), and 3β-acetoxy-20-taraxasten-22-one (5), together with 20-taraxasten-3β-ol (6) and ptiloepoxide (7) were isolated from the aerial roots of Ficus microcarpa.Their structures were elucidated by spectroscopic and chemical methods.
