[Method] The sample was dissolved in methanol and acetonitrile - water was used as the mobile phase. The residue was separated by reversed-phase high performance liquid chromatography with Agilent TC-C18 column and UV detector and quantified by external standard method. [Result] The linear correlation coefficient was 0.995, the coefficient of variation of precision was 0.2% and the average recovery was 100.2%. [Conclusion] The method can completely meet the requirements of quantitative analysis, with the advantages of simple, good linear relationship, high precision and high accuracy.
