摘　　要：采用高效液相色谱法分析甲维盐微乳剂,以甲醇+0.2%三乙胺溶液+乙腈(V:V:V=30:30:40)为流动相,采用Xterra RP18 4.6150mm色谱柱,检测波长245nm,测得54±2℃条件下14d分解率为3.42%。室内毒力测定热贮前后1%甲维盐微乳剂LC_(50)分别为0.499 mg/L和0.524 mg/L,热贮分解率为4.78%,与高效液相色谱测定结果基本一致。An high performance liquid chromatography(HPLC) method was used to analyze thermal stability of emamectin benzoate (ME),using methanol + 0.2%triethylamine solution + acetonitrile(V methanol:V triethylamine:V acetonitrile = 30:30:40) as the mobile phase,by Xterra RP18 4.6150mm column and UV detection at 254 nm,the decomposition rate was 3.42%under 54±2℃after 14d.Toxicity before and after thermal storage,LC_(50) of one percent a salt - dimensional micro - emulsion were 0.499 mg / L and 0.524 mg / L,thermal decomposition rate of storage was 4.78%,the results were bsaic agreement with the results obtained by HPLC.
