Abstract: Objective To establish an HPLC quantitative method for the content determination of baicalin in Kangdeling capsule. Methods The chromatography column was Agilent Tc-C18-WR (4.6 mm×250 mm,5 μm),and the column temperature was 30 ℃.The mobile phase consisted of acetonitrile and 0.5‰ phosphoric acid (26:74).The flow rate was 1.0 ml/min, and the detection wavelength was 265 nm. Results The retention time of baicalin was about 16 min. The calibration equation was Y=22 114.67 X-112 836.7(r=0998 8)with good linearity in the range of 5.410-108.2 μg/ml for baicalin. The average recovery was 98.78% while RSD were 0.74%. Conclusion This method is simple, time-saving and accurate which could be used to routine analysis of baicalin in Kangdeling capsule.
