Abstract:Objective To establish a high performance liquid chromatography method for the simultaneous determination of puerarin, daidzein, aurantio-obtusin and chrysophanol in Liuwei Gelan Jiangzhi Tablets. Methods High performance liquid chromatography method was used. Phenomenex Gemini C18 (250 nm × 4.6 mm, 5 um) was used as the chromatographic column. The mobile phase was acetonitrile-0.1% phosphoric acid aqueous solution. The gradient elution method was used. The detection wavelength was 285 nm, the column temperature was 30℃, and the flow rate was 1.0 mL/min. Results The injection quantities of puerarin, daidzein, aurantio-obtusin and chrysophanol showed good linear relationship with peak area in the range of 0.014 58-0.065 62 mg/mL, 0.1074-0.2417 mg/mL, 0.014 58-0.065 62 mg/mL, 0.012 01-0.054 04 mg/mL (r = 0.995 94, 0.999 95, 0.999 97, 0.991 57), respectively, and the average recovery rates were 99.0%, 102.9%, 104.1%, 104.1%, and RSD were 0.390%, 0.910%, 0.050%, 0.057% (n = 6), respectively. Conclusion The method is simple, accurate, stable and reproducible. It can be used for the quality control of Liuwei Gelan Jiangzhi Tablets.
