Abstract:
Seven new taraxastane-type triterpenes-20-taraxastene-3beta, 22alpha-diol (1), 3beta-acetoxy-20-taraxasten-22alpha-ol (2), 3beta-acetoxy-22alpha-methoxy-20-taraxastene (3), 3beta-acetoxy-20alpha,21alpha-epoxytaraxastan-22alp ha-ol (4), 3beta-acetoxy-19alpha-methoxy-20-taraxastene (5), 3beta-acetoxy-19alpha-hydroperoxy-20-taraxastene (6), 3beta-acetoxy-20alpha,21alpha-epoxytaraxastane (7)-were isolated from the aerial roots of Ficus microcarpa. Their structures were elucidated by spectroscopic and chemical methods.
