Gardeniae Fructus
Ophiopogonis Radix were indentified by TLC.The content of baicalin and geniposide were determined by HPLC.Cosmosil C18-MS-Ⅱ column was used with the mobile phase of methanol-0.2% phosphatic acid in a gradient manner.The detection wavelength was set up at 238 nm.The flow rate was 1.0 mL · min-1and the column temperature was set at 30 ℃.Result: The average recovery was 95.4% with RSD 2.2% for baicalin
99.3% with RSD 1.7% for geniposide(n=6).Conclusion: The method is simple
exclusive and accurate
which can be used for determination and quality control for Qingrejiedu Tablets.
