Problems solved by technology

We first applied for the patent of publication number CN1686294A for this Chinese medicine preparation, which discloses the prescription and preparation method of its Chinese medicine preparation for the treatment of coronary heart disease. The quality standard of the preparation only controls the content of salvianolic acid B and tanshinone IIA, which is obviously not enough to control the internal quality of traditional Chinese medicine preparations

Abstract

The invention relates to a method for determining fingerprint spectrum of traditional Chinese medicine for treating coronary heart disease. The method comprises the following steps: preparing a test solution, preparing a reference solution, and carrying out gradient elution under the chromatographic conditions that an Agilent ZORBAX Extend C18 chromatographic column is used as a filling agent, a mobile phase A is methanol and a mobile phase B is 0.4% phosphoric acid water solution; determining under conditions that the flow velocity is at 1.0ml / min, the column temperature is at 35 DEG C and the detection wavelength is 230-240nm, thus obtaining the fingerprint spectrum of traditional Chinese medicine. The method has the characteristics of being simple and convenient, good in reproducibility, more in characteristic peaks, accurate and reliable, and the like, and the quality of the traditional Chinese medicine preparation can be controlled effectively by the established fingerprint spectrum.

Description

technical field [0001] The invention relates to a method for determining fingerprints of traditional Chinese medicine preparations for treating coronary heart disease, in particular to a high-performance liquid chromatography fingerprint method for determining effective components in traditional Chinese medicine preparations, and belongs to the technical field of medicine. Background technique [0002] Traditional Chinese medicine has a long history in my country. As the material carrier of traditional Chinese medicine for disease prevention and treatment, its inherent quality is directly related to clinical efficacy and safety. Therefore, establishing a quality control system for TCM preparations that can be accepted by the international pharmaceutical industry is one of the key issues in the development of TCM. The quality control of traditional Chinese medicine is an important part of the modernization of traditional Chinese medicine, and fingerprint technology is conside...
