Title: Determination of hydrochloric berberine in Quban powder by HPLC
Abstract: OBJECTIVE To establish an accurate method for the determination of hydrochloric berberine in Quban powder.METHOD The HPLC method employed a C18 column,with acetonitrile methanol-0.01mol·L-1 phosphoric acid(50:50)as the mobile phase.The wave length of detection was 350nm.RESULTS The linear range was 0.065~0.387μg(r=1.0000).The recovery was 99.34%.The relative standard deviation was 1.6%(n=5).CONCLUSION It can be a way of reference for controlling quality.
