摘　　要：本文用薄层色谱法以丙酮:甲醇:水:氯仿=12:3:3:5为展开剂对以盐形式存在的■化合物进行了分析,并研究了 它的色谱行为的特殊性。通过Rf值对照法、薄层-红外光谱法对待测组分进行了鉴定。建立了双波长薄层色谱扫描碘显色外标单点校正定量法,并对不同定量方法进行了比较。测量结果相对误差和相对偏差均为±2%。By using TLC method the compound ■ existing in its salt form was separated from its decomposed products and by-products with the developing agent consisting of acetone:methanol: water:chloroform = 12:3:3:5. Its special TLC behavior was studied and proved.It was identified by the Rf value method and the TLC-IR method. By using the dual-wavelength TLC-scanner its content was determined with iodine vapor visualization and the external standard one-point calibration method. By comparing the results obtained with different methods a new alternative sample application method is presented, with which the disadvantage of the unstability of iodine vapor method usually encountered has been overcome and the accuracy has been improved. The relative error of the recovery rate is within ± 2 %,
