【Abstract】 [Aims] A HPLC method for the determination of bixafen TC was developed. [Methods] Waters Alliance e2695 HPLC system and Eliet C18 column were adopted for the separation and quantification. The mobile phase was methanol and water(69:31, by vol) at the flow rate of 1.0 m L/min and the column temperature of 30 ℃. The detection wavelength was 259 nm. [Results] There was a good linear relationship between the concentration and the peak area of bixafen in the concentration range of 0.0396-0.7920 g/L, and the linear regression coefficient was 0.9999. The relative standard deviations of precision and repeatability test were 1.17 and 0.54%, respectively. The average recovery was99.88%. [Conclusions] The method has high column efficiency, sensitivity and accuracy, and could be used for the quantitative analysis of bixafen TC.更多还原
