摘　　要：建立了在同一色谱条件下测定混剂中啶酰菌胺和腐霉利含量的方法。采用200mm×4.60mm(i.d.)SinoChrom ODS-BP柱分离,以乙腈-水(体积比为60∶40)为流动相,在225nm紫外检测波长下,经保留时间定性确证,峰面积外标法进行定量分析。结果表明:啶酰菌胺与腐霉利的线性相关系数分别为0.999 9和0.999 9;变异系数分别为0.34%和0.59%;平均加标回收率分别为99.32%和99.20%。A LC method for the determination of boscalid and procymidone in WG formulation was developed with SinoChrom ODS-BP column, acetonitrile-water（ 60 ∶ 40 v/v） as mobile phase, and detection wave length at 225 nm. The results demonstrated that the correlation coeffi cients of boscalid and procymidone were 0.999 9 and 0.999 9. The variation coefficients were0.34% and 0.59%. The average recoveries were 99.32% and 99.20%. The method is simple,rapid, accurate and suitable for the analysis of this mixed fungicide.
