摘　　要：[目的]建立一种同时分析噻菌灵、戊唑醇和抑霉唑的高效液相色谱法。[方法]采用液相色谱法于Phenomenex C18柱上用甲醇和庚烷磺酸钠缓冲溶液(体积比60∶40,磷酸调pH值2.8)为流动相,利用紫外二极管阵列(DAD)检测器,在最大吸收波长处对试样中噻菌灵、戊唑醇和抑霉唑3组分进行分离和定量检测。[结果]噻菌灵、戊唑醇和抑霉唑的平均回收率分别为100.4%、100.2%、100.6%;变异系数分别为0.116%、0.274%、0.176%。[结论]高效液相色谱法灵敏快速,适合噻菌灵?戊唑醇?抑霉唑悬浮剂含量检测。A HPLC method was developed for the quantitative determination of thabendazole·tebuconazole· imazalil SC.[Methods]The mobile phase was a（60∶40,by vol） mixture of methanol and heptane sulfonate sodium buffer,a Phenomenex C18 chromatographic column was used and DAD detector at their maximum absorption wave.[Results]The average recovery of thabendazole,tebuconazole,imazalil were 100.4,100.2,100.6% respectively.And the variation coefficient were 0.116,0.274,0.176%.[Conclusions]The method was simple,quick and suitable for the analysis of thiabendazole·tebnconazole·imazalil SC.
