| Abstract: | Objective To establish the TLC identification method for Zidi mixture. Methods According to the optimization of developing solvent, chromogenic agent, dropping amount, and the investigation of TLC plate, temperature, relative humidity, TLC method for Zidi mixture has established. Results The best conditions were as follow： methylbenzene-acetoacetate-glacial acetic acid （3 ： 2 ： 1）as developing solvent, and l%FeC13 ethanol solution as chromogenic agent; The optimum dropping amounts of the sample and the control were 4 and 2 microlitres;TLC plate, temperature and relative humidity had no influence to the results. Conelusion The method is simple, specific and durable. It can be used for the quality control of Zidi mixture. |
