摘要：

Two new triterpenoids, poricoic acid A and B were isolated from the surface layer of Poria cocos. The structures of poricoic acid A and B were elucidated to be 16-alpha-hyroxy-3,4-secolanosta-4(28),7,9(11),24(31)-tetraen-3,21-dioic acid, and 16-alpha-hydroxy-3,4-secolanosta-4(28),79(11),24-tetraen-3,21-dioic acid, respectively.
