Abstract

The invention discloses a method for determining the fingerprint of a Qibai Pingfei granule, and the fingerprint of the granule. The method comprises the following steps: respectively carrying out extraction on a Qibai Pingfei granule sample and schizandrin by using a methanol solution to obtain a sample solution and a reference substance solution, and carrying out high performance liquid chromatography on the sample solution and the reference substance solution by using the schizandrin, caffeic acid, ferulic acid, deoxyschizandrin, schisandrin B and schisantherin A as reference substances toobtain the fingerprint. The fingerprint of the Qibai Pingfei granule, established by using the method, can effectively characterize the quality of the Qibai Pingfei granule, and is in favor of comprehensively monitoring the quality of medicinal materials. The method has the advantages of simplicity, stability, high precision and good reappearance, and can be used to rapidly and accurately identifythe authenticity and the quality.

Description

Technical field [0001] The invention belongs to the technical field of quality identification of traditional Chinese medicines, and in particular relates to a method for determining the fingerprint spectrum of Qibaipingfei granules and a fingerprint spectrum of Qibaipingfei granules established by the method. Background technique [0002] The fingerprint of Chinese medicine refers to the chromatogram or spectrum that can indicate the chemical characteristics of certain Chinese medicinal materials or Chinese medicinal preparations after proper processing and using certain analytical methods. The fingerprint of traditional Chinese medicine is a comprehensive and quantifiable identification method. It is based on the systematic study of the chemical components of traditional Chinese medicine. It is mainly used to evaluate the authenticity, excellence and stability of the quality of Chinese herbal medicines and semi-finished products of Chinese medicine preparations. "Integrity" and ...
