Abstract

The invention provides an establishment method of fingerprint spectrum of a traditional Chinese medicine composition, and a method for detecting the constituents in the traditional Chinese medicine composition. The traditional Chinese medicine composition comprises the following active ingredients: dried tangerine peels, radix peucedant, snakegourd seed, pinellia tuber, Radix Asteris, white mulberry root-bark, perilla fruit, bitter apricot seeds, common coltsfoot flowers, heartleaf houttuynia herb, poria and liquorice roots. The establishment method of the fingerprint spectrum comprises: detecting the retention times of compounds in the traditional Chinese medicine composition by adopting high-performance liquid chromatography.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and in particular relates to a method for establishing a fingerprint of a traditional Chinese medicine composition. The traditional Chinese medicine composition is Kechuanshun Wan. Background technique [0002] Traditional Chinese medicine compositions (Chinese patent medicines) based on the theory of traditional Chinese medicine generally have a variety of medicinal flavor components; during the preparation process of the pharmaceutical composition, different components may react with each other, resulting in more complex components of the pharmaceutical composition. It is difficult to reflect the chemical characteristics of the composition as a whole due to the limited amount of information only by qualitative or quantitative detection of one or several components. With the development of modern analytical techniques, fingerprinting has become an internationally recognized quality control mo...
