Paeonia sinjiangensis K. Y. Pan is a perennial herb belonging to the family Ranunculaceae which is one of the most important crude drugs in traditional Chinese medicine, used as an anti-inflammatory, analgesic and sedative agent. This paper deals with the detailed total phenolic content of the crude drug Paeonia sinjiangensis K.Y. Pan, from Xinjiang, China. Meanwhile, it tested for antimicrobial activity in this study. The total phenolic content of Paeonia sinjiangensis K.Y. Pan was 9.58 ? 1.03 mg QE/g dry wt. The microscopic characteristics were investigated, which offer data to differentiate the drug from its other species. It showed strong inhibition against Blastomyces albicans and possessed considerable activity against Staphylococcus aureus and Escherichia coli.
