Abstract:
Objective: To establish an HPLC determination method for the quantitative indicators in Qubai granules( stilbene gly-cosides, ferulic acid and paeonol). Methods: A dual-wavelength HPLC assay was used with the following conditions: a chromatogra-phy column ODS (150 mm×4. 6 mm, 5 μm) was used, the mobile phase was methanol: 0. 1% phosphoric acid with gradient elution, the column temperature was 35℃, and the injection volume was 10 μl. Results: The linear ranges of the three active constituents were 1.56-156.00 μg·ml-1(r stilbeneglycoside=0.999 8)、1.00~100.00 μg·ml-1(rferulicacid=0.999 8),1.61~161.00 μg·ml-1(rpaeonol=0. 999 7), respectively, and the average recoveries of the three constituents were between 100. 33% and 100. 76% with the RSDS less than 2% (n=6). Conclusion: The method is simple, stable and reliable, which can be used for the quality control of Qubai granules.
