Abstract:Objective: To establish a HPLC method for the determination of baicalin and phillyrin in Qingrejiedu tablets. Method: The Kromasil Cl8 column (250mm×46mm,5μm) was used. The mobile phase consisted of methanol-aeetonitrile-water-phosphoricacid ( 65 : 15 : 19.5: 0.5 ). The flow rate was 1.0 ml·min^-1. The detecting wavelength was at 230 nm. Result: The calibration curves were linear within the range of 1.42 - 22.78 μg for baicalin ( r = 0. 999 8 ) , and 1.12 - 17.92 μg for phillyrin ( r = 0. 999 5 ), respectively. The average recovery rates were 98.2% and 95.9% ( n = 5 ) with RSD of 1.2% and 1.0% , respectively. Conclusion: The method is rapid and accurate. It can be used for quality control of Qingrejiedu tablets.
Keywords:HPLC  Qingrejiedu tablets  Baicalin  Phillyrin  Content determination
