Quality standard for Guli Granules / 中成药

ABSTRACT

AIM: To establish the method for quality control of Guli Granules(Herba Epimedii,Radix Puerariae Lobatae,Rhizoma Curcumae Longae,Radix Achyranthis Bidentatae,Fructus Psoraleae,etc.). METHODS: Radix Puerariae,Rhizoma Curcumae Longae,Radix Achyranthis Bidentatae and Fructus Psoraleae in this medicine were identified by TLC.The icarrin content in this medicine was determined by HPLC.The acetonitril-water(28∶72) solution was used as the mobile phase,the column was C_(18),the flow rate was 1.0 mL?min~(-1).The detection wavelength was at 270 nm. RESULTS: These herbs could be identified by TLC.For Icarrin,the linear range was from 17 to 85 ?g?mL~(-1),and the average recovery was 98.32% with RSD of 1.67%. CONCLUSION: The method is simple,reliable,accurate and can be applied to the quality control of the preparation.
