Abstract
Objective: To establish a method for determination of Berberine hydrochloride in Qingfei Yihuo Wan. Method: The analysis was performed on a Diamonsil-C18 column using acetonitrile-water (54 ∶46) (every 100 mL add in 0.34 g SDS and 0.17 g NaH2PO4
pH adjusted to 3.0 with phosphoric acid) as mobile phase. The flow rate was 1.0 mL ·min-1
and the detection wavelength was 350 nm. Result: The linear range of berberine hydrochloride was 5.00-35.00 mg ·L-1 ( r =0.999 2). The average recovery for berberine hydrochloride was 97.6%
precision of the method was 1.39% ( n =6). Conclusion: The method can be used for quantitative determination of Berberine hydrochloride in Qingfei Yihuo wan.
