Following the investigation of foliasalaciosides A(1), A(2), B(1), B(2), C, and D, seven new megastigmane glycosides named foliasalaciosides E(1)-I (1-7), together with four known constituents, were isolated from the leaves of Salacia chinensis LINN. collected in Thailand. The absolute stereostructures of the new compounds were characterized on the basis of chemical and physicochemical evidence, including
在调查了叶甲ala苷A(1),A(2),B(1),B(2),C和D之后,命名为叶甲ala苷E(1)-I(1-7)的七个新的大麦角甙苷以及从Salacia chinensis LINN的叶子中分离出四种已知成分。在泰国收集。根据
