| 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XterraRP184．6150mm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Lc50分别为0．499mg／L和0．524mg／L，热贮分解率为4．78％，与高效液相色谱测定结果基本一致。

| Abstract: | An high performance liquid chromatography （HPLC） method was used to analyze thermal stability of emamectin benzoate （ME）, using methanol ＋ 0. 2% triethylamine solution ＋ acetunitrile （V methanol： V triethylamine： V acetonitrile = 30： 30： 40） as the mobile phase, by Xterra RP18 4. 6150ram column and UV detection at 254 nm, the decomposition rate was 3.42% under 54 ±2℃ after 14d. Toxicity before and after thermal storage, LCso of one percent a salt- dimensional micro- emulrlsion 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 ob- tained by HPLC. |
