To perfect the standard of Poria cocos (Schw.).TLC and HPLC fingerprint were used to identify triterpenoids from P. cocos. The content of pachymic acid and dehydropachymic acid were determined by HPLC.Pachymic acid showed a good linear relationship at a range of 1.52 - 7.60 microg/ml, r = 0.9994, the average recovery was 96.90%, RSD = 1.09%. Dehydropachymic acid had a good linear relationship at a range of 0.35 - 1.75 microg/ml, r = 0.9991, the average recovery was 97.86%, RSD = 1.52%.The methods are special and accurate, and can be used for the quality control of P. cocos.
