Abstract
Crystals I-N were isolated from the ethereal extracts of Poria cocos and identified respectively as O-acetyl-pachymic acid (I), 3 beta-hydroxy-lanosta-7,9(11),24-trien-21-oic acid (II), beta-amyrin acetate (III) and 3 beta-hydroxy-16 alpha-acetoxy-lanosta-7,9(11),24-trien-21-oic acid (N). Crystal III was obtained from P. cocos for the first time, and crystal N was newly discovered.
