摘要
本文研究了中药材西维因残留量的薄层色谱 荧光测定 .采用环已烷∶丙酮∶氯仿 =5∶1∶1 (V V)作为展开剂 ,直接用荧光测定 .本法灵敏度高 ,且易操作 ,当添加水平为 0 0 1mg mL时 ,回收率在 84 %～ 1 1 1 %之间 ,线性相关系数为 0 9998,检测限达到 1 0ng .
A method for determination of carbaryl residue in Chinese herbs by thin layer chromatography with fluorescence detection was studied.The samples were developed by cyclohexane:actone:chloroform=5∶1∶1( V/V) and were directly measured by fluorescence emission.The method had high sensitivity and was easy to be operated.As spiked level was 0 01?mg/mL,the recovery was between 84% and 111%,the correlation coefficient was 0.999?8,the detection limit was 10?ng.
