Abstract

Cimicifugae Rhizoma (sheng ma) is a well-known traditional Chinese medicine, which has been demonstrated to possess anti-inflammatory, antipyretic and analgesic activities. In the present study, a simple and efficient HPLC-DAD (high-performance liquid chromatography coupled with diode array detection) method was developed and validated for simultaneous quantification of 19 chemical components (including 16 phenolic acids, one coumarin and two alkaloids) in Cimicifugae Rhizoma. The result indicated that this method could effectively evaluate the quality of Cimicifugae Rhizoma and provide a valuable reference for further study. Additionally, the antioxidant activity of Cimicifugae Rhizoma was evaluated by DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging assay. The results showed that the content of phenolic acids and antioxidant activity exhibited significant correlation coefficients.

Keywords: Cimicifugae Rhizoma; HPLC-DAD; antioxidant activity; phenolic acids; simultaneous quantification.
