Two New Tetranortriterpenoids from Amoora dasyclada

摘要

Two new tetranortriterpenoids 3-oxo-24, 25, 26, 27-tetranortirucall-7-ene-23(21)- lactone, 3á-hydroxy-24, 25, 26, 27-tetranortirucall-7-ene-23(21)-lactone were isolated from Amoora dasyclada. Their structures were elucidated by spectroscopic evidences.
