Comparison of methods for original drug of trifloxystrobin by HPLC and GC
Comparison of methods for quantitative analysis of the active ingredients of trifloxystrobin was determined by HPLC and gas chromatography.By a diode array detector wavelength at 250nm and FID detector,the active in-gredient of trifloxystrobin was analyzed quantitatively With a Agilent C18 column and a AE.SE-30 Capillary column,using methanol and water as the mobile phase and dicyclohexyl phthalat as the internal standard.The results showed that the linear correlation coefficients of HPLC and gas chromatography were 0.999 9 and 0.999 5,the standard devia-tions were 0.21 and 0.19,the coefficient of variation was 0.21%and 0.19%,and the average recovery was 99.74%and 99.67%respectively.By comparison,the both methods are good for quantitative analysis of trifloxystrobin.
