Abstract

The invention relates to a determination method for the HPLC-ELSD fingerprint spectrum of Lotrimin Sol Lotrimin. The determination method comprises the following steps of: preparing a sample solution;preparing a control sample solution; injecting the solutions into a liquid chromatograph (evaporative light scattering detector) to determine; and judging whether the quality data of the Lotrimin SolLotrimin obtained by the determination method is qualified or not on the basis of the standard fingerprint spectrum. The method is simple, rapid, accurate, stable and reliable, can be used for the quality control of a Lotrimin Sol Lotrimin sample, and can comprehensively, objectively and scientifically evaluate the quality of the Lotrimin Sol Lotrimin so as to guarantee the effectiveness of the preparation.

Description

technical field [0001] The invention relates to a method for analyzing the fingerprints of traditional Chinese medicines, in particular to a method for determining the fingerprints of Huangshi Xiangsheng Pill preparations, and the obtained fingerprints of Huangshi Xiangsheng Pills preparations. technical background [0002] The composition of traditional Chinese medicine and compound preparations in my country is very complicated, because its therapeutic effect is carried out through overall coordination. Therefore, it should be taken as a whole when evaluating its quality. However, the general quality standard is to evaluate the content of a certain component in a traditional Chinese medicine or a compound prescription. It is difficult to control its intrinsic quality like this. Therefore, in order to improve and highlight the overall characteristics of traditional Chinese medicine, establish quality control standards and evaluation models that conform to the characterist...
