摘　　要：利用制备液相色谱对肟菌酯原药和啶氧菌酯制剂进行纯化,得到的标准物质采用超高效液相色谱仪(UPLC-PDA)和质谱(MS)结合标准品对照的方式进行定性分析,并进行了均匀性检验和稳定性检验,最终以8家实验室合作定值的方式确定所制标准物质的量值。Trifloxystrobin TC and picoxystrobin formulation were purified by preparative liquid chromatography, and then qualitative analysis of the purification were studied by UPLC-PDA and MS with standard substance. The homogeneity and stability were tested, and the value of the reference materials were determined through eight-laboratory cooperation.
