The RP-HPLC assay was performed on a reversed-phase Cl8 column with a gradient elution. The mobile phases consisted of methanol and water containing 1% (v/v) acetic acid. The flow rate was 1.0 mL/min and the detection wavelength was set at 300 nm. All calibration curves showed good linearity (r2〉0.9941) within test ranges. The results of intra-day precision, inter-day precision, and accuracy were satisfactory. The overall recoveries were in the range of 90.13%-102.48%. The method was successfully applied to quantify nine bioactive compounds in six samples. Baseline resolution for all nine major compounds was achieved. This method could be used as a suitable quality control assay for Wuzhuyu decoction.展开更多
