| Abstract: | Objective： To establish a method for the determination of baicalin in Qingreantai Granule. Methods： The Alhima C18 （4.6 min×250 mm, 5 um） was used with CH3OH-H3PO4-H2O（47：53：0.2） as mobile phase, the detection wavelength was set at 280 nm, and flow rate was 1.0 ml/min. Results： The calibration curve of baicalin was linear at the range of 0.208 4- 4.168 0 ug（r=-0.999 7）.The average recovery was 100.94%, RSD=2.5%. Conclusion： This method is simple and accurate, it can be used for the quality control of Qingreantai Granule. |
