Abstract:
Object To set up the quantitative method for determining the puerarin in Gegen Qinlian Decoction (GQD) by RP-HPLC and to study the change of puerarin contents in various combinations of GQD. Methods L 8(2 7) orthogonal design and statistic analysis (SPSS 10.0) were used, the puerarin contents in the samples were determined by HPLC. Results Influence of Radix Scutellaria, Rhizoma Coptidis and Radix Glycyrrhizae Preparata on the puerarin content in GQD was insignificant. And interactions between two of three were insignificant too. In this experiment, puperarin in the sedimentation was found in the compatible decoction of Rhizoma Coptidis and Radix Puerariae. Conclusion The puerarin content is not markedly influenced by Radix Scutellaria, Rhizoma Coptidis and Radix Glycyrrhizae Preparata. Maybe, the change of pH is relevant to the sedimentation in the compatible decoction contained Rhizoma Coptidis. and Radix Puerariae
