[Methods] The sample was separated and analyzed quantitatively on C18 column and UV detector at 240 nm, using acetonitrile, water and acetic acid as mobile phase by reverse phase HPLC. [Results] The results showed that the linear correlation coefficients of atrazine and mesotrione were 0.999 7 and 0.999 3. The standard deviation were 0.044 and 0.048, the variation coeffi cients were 0.89 and 0.32%, the average recovery rates were 99.73 and 99.96%, respectively. [Conclusions] The method was simple, rapid, accurate and suitable for the qualitative and quantitative analysis of atrazine·mesotrione 26% SC samples. Key words: atrazine; mesotrione; HPLC; analysis 莠去津(atrazine),化学名称为2-氯-4-二乙胺基-6-异丙胺基-1,3,5-三嗪,是玉米田中使用多年的三氯苯类除草剂,可防除多种一年生阔叶
