摘 要:采用高效液相色谱法,在同一色谱条件下对稻·噁乳油中所含有效成分稻瘟灵和噁霉灵同时进行含量测定。色谱条件为:使用Nova-PaK C18 250 mm×4.6 mm(i.d)不锈钢色谱柱,流动相v(甲醇) ∶ v(水)=70 ∶ 30,流速1 mL/min,检测波长为220 nm。测定方法中稻瘟灵和噁霉灵的回收率分别在98.8%~100.3%和98.6%~100.0%之间,变异系数分别为0.54%和0.52%,证明本方法快速、准确、可靠。

Abstract:The content of kiazine and oxamyl in the formulation kiazine-oxamyl emusifiable concentrate was determined by HPLC in the same chromatogram conditions. The operating conditions by HPLC were C18 column(250 mm× 4.6 mm), v(methanol) ∶ v(water)=70 ∶ 30 as mobile phase,1 mL/min as flow speed and wavelength 220 nm. The recoveries of kiazine and oxamyl were 98.8%~100.3% and 98.6 %~100.0%,respectively,and their coefficients of variation were 0.54% and 0.52%,respectively,indicating that this method is fast,accurate and repeatable.
Key words:kiazine;oxamyl; high performance liquid chromatography
