2,3-Seco- and 3,4-seco-tirucallane triterpenoid derivatives from the stems of Aphanamixis grandifolia Blume.
Six 2,3-seco-tirucallane triterpenoid derivatives (aphanamgrandins A-F), three 3,4-seco-29-nor-tirucallane triterpenoid derivatives (aphanamgrandins G-I), one 3,4-seco-tirucallane triterpenoid (aphanamgrandin J), two tirucallane triterpenoids [aphanamgrandin K and (23Z)-25-hydroxy-tirucalla-7,23-diene-3-one], and three known triterpenoids were isolated from stems of Aphanamixis grandifolia Blume, and their structures were established by extensive spectroscopic and X-ray crystal diffraction studies.
