To establish an HPLC method for determination of pachymic acid in poria cocos of different habitats. Methods:Determined the content of pachymic acid in poria cocos of 11 different habitats with waters symmetry C18 column(5μm,4. 6 í150mm), the mobile phase was acetonitrile and 0. 5% phosphoric acid solution. Results: the content of pachymic acid in poria cocos of dabieshan area and Yunnan Guizhou province were significant higher than other habitats. Conclusion:A simple, accurate method is established for quality control of poria cocos.
