摘　　要：对蔬菜组织富含多酚类和色素等杂质的特点,对高效液相色谱法HPLC分析蔬菜中拟除虫菊酯测类波杀长虫剂24的2n前m处条理件方下法,用进配行备了Z改or进ba,x在R流x-S动il相柱溶、紫剂外正检己测烷器-乙的酸高乙效酯液(相95色︰谱5,仪V︰进V行)及待流测速组1分m的l/m分i离n,检和测定。结果表明该方法适合蔬菜中拟除虫菊酯类杀虫剂的分析测定。To deal with the existence of large amount of polyphenols, pigments and other impurities, an improved HPLC method suitable for analyzing pyrethroids in vegetables including modified sample preparation procedures and chromatography profiles was proposed. The HPLC operating conditions were Zorbax Rx-Sil column, n-hexane and ethyl acetate （95 ： 5, V ： V） as mobile phase with the flow rate of 1 ml/ min and UV detection wavelength at 242 nm.
