Triterpenes and Saponins from Ilex psammophila

Abstract

Two new saponins were isolated from the leaves of Ilex psammophila . Their structure was established by chemical and spectroscopic methods as 28- O - g - d -glucopyranosylester of 20( S )-ilexgenin A ( 4 ) and 28- O - g - d -glucopyranosylester of 20( S )-3 g ,19 f ,24-trihydroxyurs-12-ene-23, 28-dioic acid ( 5 ).
