Abstract
The separation of triterpene acids was achieved from Poria cocos (Schw.) Wolf by TLC after treatment with Ph2CNN or RX under mild condition followed by selective hydrolysis of ester groupings. Three triterpene acids, 3 beta-acetoxyl-16 alpha-hydroxy-lanosta-8,24(31)-diene-21-oic acid (I), 3-oxo-16 alpha-hydroxy-lanosta-7,9(11), 24(31)-trien-21-oic acid (II) and 3 beta, 16 alpha-dihydroxylanosta-7,9(11), 24(31)-trien-21-oic acid (III) were isolated.
