Determination of Hyperoside in Jintu Liangguang Capsules by RP-HPLC / 中药新药与临床药理

ABSTRACT

Objective To establish a determination method for the hyperoside in Jintu Liangguang Capsules. Methods Reverse-phase HPLC with Dikma Diamons C18 column was applied. The chromatographic conditions were as followsmethanol-0.025 mol/L of thophosphoric acid (40 ∶60) as the mobile phase,detection wavelength at 370 nm,column temperature set at 40 ℃and the flow rate being 0.8 mL/min. Results The linear range of calibration curve was 0.303 ～1.818 ug/uL for the hyperoside (r=0.999 6). The average recovery was 95.2 %and RSD was 1.3 %. Conclusion The method is simple and accurate,and can be used for quantitative analysis of Jintu Liangguang Capsules.
