Abstract:
Objective To develop a method of quantitative analysis of multi-components by single marker( QAMS) for determination of quercetin, kaempferide,isohamnetin in Chuipencao granules,providing method to control the quality of Chuipencao granules.Methods The analysis was performed at 30 ℃,on an Shimadzu C18 column(250 mm ×4.6 mm,5μm),and the mobile phase was methanol-0.4% phosphoric acid solution .The flow rate was 1.0 mL/min, and the injection volume was 10 μL.Quercetin as a reference to establish the relative correction factor kaempferol and between isorhmnetin, the method was evaluated for reproducibility, and the difference between calculated and measured values was compared. Results Quercetin, kaempferol and isorhmnetin respectively 32.36-426.43μg, 11.56-136.87μg, 10.45-155.68μg showed a good linear relationship, and the regression equation was: Y=3625.8X-13658 (R2 =0.9998), Y=2682.9X-10253(R2 =0.9999), Y=3012.2X-11223 (R2 =0.9999).The average recoveries were 99.3%, 99.6%, 98.5% (RSD were less than 1.0%).Determination of 10 batches of Chuipencao granules with QAMS and external standard method, kaempferol and isorhamnetin were measured, and measured values were basically the same.Conclusion The QAMS method is reliable and accurate, which might be used for the quality control of Chuipencao granules.
