摘　　要：以薄层层析法分离、薄层扫描定性、紫外分光光度法和气相色谱法定量相结合的方法探索了油酸烟碱·氯氰乳油中烟碱的主要存在形式和油酸的作用。结果表明，在二甲苯为溶剂的油酸烟碱·氯氰乳油制剂中，９０％以上的烟碱是以游离态形式存在的，油酸的作用主要是调节制剂ｐＨ值，抑制氯氰菊酯分离。The state of nicotine and main function of oleic acid in emulsion concentration (EC) of Nicotineoleate·Cypermethrin are studied with a combination method of layer chromatography,layer scanning,UV Spectrophotometer and gas chromatography.The results show that, when xylene is used as solvent,more than 90 percent of nicotine in the EC is in free state,and that the nicotine exhaused in nicotine oleate forming is 10 percent at most.The main function of oleic acid is to adjust the EC pH,and then to control the decomposition ratio of cypermethrin.
