Title: Determination of baicalin in Biyanning capsules by HPLC
Abstract: Objective: To determine the content of baicalin in Biyanning capsules by RP-HPLC.Methods: C18 column was used with the mixture of methanol -H 2O-giacial acetic acid (48∶51∶1) as the mobile phase at a flow rate of 1.0 mL.min -1 with the detection wavelength at 277 nm. Results: The method proved to be linear over the range of 0. 21~1.05 μg, r=0.9998; the recovery of the assay was 97.9%. Conclusion: The method appears to be simple, reliable accurate and can be used to the quality control of the preparation.
