Abstract: Objective: To study the quality of Poria from different areas, and to provide basis for the establishment of quality standards of Poria and its development and utilization. Methods: (1) The contents of water, ash and extractives in Poria cocos are determined according to the relevant methods of Chinese Pharmacopoeia 2015. (2) UV-visible spectrophotometry was used to determine the content of water-soluble polysaccharides and total triterpenes in Poria cocos. (3) The content of Poria acid in Poria was determined by high performance liquid chromatography. Results: The extracts, total triterpenoids,and Poria acid from Guizhou block were the highest. The extract of Poria from Yunnan is between 3.39% and 3.99%, the total triterpene content of Poria is from 0.25% to 0.30%, and the content of Poria acid is from0.07 to 0.09%. The polysaccharide content of Poria is between 0.21 and 0.42. Except for the polysaccharide content of Poria, the overall difference was not significant. The extracts of Poria from Anhui ranged from 2.65% to 4.01%, the total triterpenes content of Poria from 0.17% to 0.31%, the content of Poria acid from 0.05% to 0.08%, and Poria’s polysaccharide content is between 0.13 and 0.42. The content of Poria from Anhui Province is quite different. The extract of Poria from Hubei is between 3.03% and 3.44%, the total triterpene content of Poria is between 0.22% and 0.25%, the content of Poria is 0.05% to 0.07%, and Poria’s polysaccharide content is between 0.11 and 0.22. The content of Poria in Hubei is not much different.
