Study on quality standard for Yijingbushen Granules / 中成药

ABSTRACT

AIM: To establish the method for quality control of Yijingbushen Granules(Herba Epimedii, Semen Cuscutae, Radix Paeoniae Alba, Rhizoma Curcumae, etc.). METHODS:Semen Cuscutae, Radix Paeoniae Alba and Rhizoma Curcumae in this medicine were identified by TLC; The content of icarrin in this medicine was determined by HPLC;The acetonitrile-2%acetum(30∶70) solution was used as the mobile phase. The flow rate was 1.0mL?min -1. The detection wavelength was set at 270nm. RESULTS:Semen Cuscutae, Radix Paeoniae Alba and Rhizoma Curcumae, could be identified by TLC on lichrospherC 18 column. For Icarrin, the linear range was from 4.32 to 21.60?g, and the average recovery was 98.69% with RSD of 1.13%. CONCLUSION:The method is simple, reliable, accurate and can be applied to the quality control of the preparation.
