摘 要:采用高效液相色譜法,在同一色譜條件下對稻·噁乳油中所含有效成分稻瘟靈和噁霉靈同時(shí)進(jìn)行含量測定。色譜條件為:使用Nova-PaK C18 250 mm×4.6 mm(i.d)不銹鋼色譜柱,流動(dòng)相v(甲醇) ∶ v(水)=70 ∶ 30,流速1 mL/min,檢測波長(cháng)為220 nm。測定方法中稻瘟靈和噁霉靈的回收率分別在98.8%~100.3%和98.6%~100.0%之間,變異系數分別為0.54%和0.52%,證明本方法快速、準確、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
