摘 要:本试验以三七、茯苓、木香为材料，研究其中氨基甲酸酯农药（克百威、抗蚜威）残留量的高效液相色谱测定方法。农药残留物用丙酮为提取溶剂，弗罗里硅土柱净化，甲醇—二氯甲烷（体积比1:9）为洗脱剂经柱层析净化后，浓缩至干以甲醇为溶剂定容，用可变波长紫外检测器检测，高效液相色谱在其最佳波长条件下进行测定。2种农药在20分钟内获得良好的分离，该方法灵敏度高且易操作。

ABSTRACT:The experiment uses Panax Notginseng, Poria cocos, Saussurea lappa as materials, including esters carbamate pesticide (grams Ya wei), resistance to bud light to detect the high performance liquid chromatographic method. Pesticide residues in acetone for extraction solvent, Florida, methanol silicon soil column purification -dichoromethane (1:9 v/v) than by the column chromatography after purification, to concentrate on methanol as solvent dry the capacity, with variable wavelength ultraviolet detector test, high performance liquid chromatography (HPLC) in its best wavelength conditions were determined. The two pesticides could be well separated within 20 minutes. The method is highly sensitive and easy in operation.
