本文报道从茯苓（Schw.）狼通过IR、UV、ESITOF-MS、HRESIS-MS、1H NMR、13 C NMR、1H-1H COSY、NOESY、HSQC和HMBC等波谱分析确定了它们的结构。
Two new lanostane triterpenoids, 29-hydroxypolyporenic acid C (4) and 25-hydroxypachymic acid (5), together with three known compounds, ergosta-7,22-dien-3beta-ol (1), polyporenic acid C (2) and pachymic acid (3), were isolated from the 95% ethanolic extract of the sclerotium of Poria cocos (Schw.) Wolf. Their structures were determined by extensive spectroscopic analyses, including IR, UV, ESITOF-MS, HRESI-MS, 1D and 2D NMR data (1H NMR, 13C NMR, 1H-1H COSY, NOESY, HSQC and HMBC).
