Problems solved by technology

At present, the quality control of chili rheumatism ointment only has identification, ointment content determination and heat resistance. It is not comprehensive to control the quality of the product based on these indicators alone. For manufacturers, there is an urgent need for a drug that can be used in the production process of the drug. Methods of Monitoring Quality

Abstract

The invention relates to a method for monitoring the quality of a hopper pepper rheumatism paste semi-finished product and a hopper pepper rheumatism paste finished product and discloses the fingerprint creating method of the hopper pepper rheumatism paste semi-finished product and the hopper pepper rheumatism paste finished product and the standard HPLC (High Performance Liquid Chromatography) fingerprint of the hopper pepper rheumatism paste semi-finished product and the hopper pepper rheumatism paste finished product. The method disclosed by the invention comprises the following steps: 1. taking a proper amount of test sample, adding methanol, ethanol or mixing at least one solvent in methanol and ethanol to extract a test sample solution; 2. creating the standard fingerprint of the hopper pepper rheumatism paste and the hopper pepper rheumatism paste semi-finished product through HPLC chromatography; and 3. comparing the fingerprint of the test sample with the standard fingerprint of the test sample, conveying the semi-finished products with qualified integral similarity to the next procedure, and delivering the finished products to be tested out of the factory as qualified products. The method disclosed by the invention has the advantages of simple and convenient method, good stability, high precision, good reproducibility, is capable of mastering the quality condition of the hopper pepper rheumatism paste from the integral characteristic condition of the chromatogram, so that the method can serve as the quality control index of the hopper pepper rheumatism paste.

Description

technical field [0001] The present invention relates to the determination method of the traditional Chinese medicine fingerprint of capsicum rheumatism ointment and its semi-finished product, more specifically, relates to the method for measuring the chemical composition of capsicum rheumatism ointment and its semi-finished product by high performance liquid chromatography (HPLC) fingerprint method. technical background [0002] Traditional Chinese medicine fingerprint refers to the spectrum or chromatogram composed of common and characteristic components in a certain Chinese medicinal material (extract, Chinese patent medicine). It is a comprehensive and quantifiable identification method. It is based on the systematic research on the chemical components of traditional Chinese medicine, and is mainly used to evaluate the authenticity, goodness and stability of the quality of Chinese medicinal materials and semi-finished products of traditional Chinese medicine preparations, ...
