Quality Standard of Zhizha Jianwei Granules / 中国药房

ABSTRACT

OBJECTIVE:To establish the quality standard of Zhizha jianwei granules.METHODS:TLC was used for the identification of Fructus Aurantii Immaturus and Fructus Crataegi.HPLC was applied for the determination of Hesperidin by which Diamonsil C18(200 mm?4.6 mm,5 ?m)chromatographic column was used and the mobile phase was acetonitrile-0.2%phosphoric acid(20∶80)with a flow rate of 1.0 mL?min-1.The column temperature was maintained at 40 ℃ and the detection wavelength was set at 283 nm.RESULTS:TLC method was proved to be specific and reproducible,and free from the interference of the negative control substance.The linear range of Hesperidin was 0.102～1.122 ?g(r=0.999 8)and its average recovery rate was 99.23%(RSD=0.20%,n=6).CONCLUSION:The established standard is suitable for the quality control of Zhizha jianwei granules.
