Abstract

The invention provides a calculus eliminating tablet fingerprint establishing method. The method comprises the following steps: preparing a reference substance, preparing a test sample, and using high performance liquid chromatography (HPLC) to obtain the fingerprint of a calculus eliminating tablet; wherein in the chromatography and system applicability tests, octadecyl silane bonded silica gel is taken as the filling agent, acetonitrile is taken as the mobile phase (A), a phosphoric acid water solution (0.2%) is taken as the mobile phase (B), methanol is taken as the mobile phase (C), the detection wavelength is 272, and the theoretical plate number calculated by schaftoside is not less than 3000.

Description

technical field [0001] The invention relates to the technical field of drug detection, in particular to a method for establishing a fingerprint of a stone tablet. Background technique [0002] The control of compound prescriptions of traditional Chinese medicine is one of the key issues restricting the modernization of traditional Chinese medicine. The theory of traditional Chinese medicine emphasizes the overall effect of traditional Chinese medicine and attaches great importance to the synergistic effect on drug efficacy. Using one or two active ingredients in traditional Chinese medicine as qualitative and quantitative indicators is far from being able to effectively control and evaluate the quality of Chinese medicine, and it is even more difficult to reflect its safety and effectiveness. sex. Traditional Chinese medicine compound is a compound preparation that combines two or more traditional Chinese medicines for disease treatment, and its quality control is more diff...
