Abstract

The invention discloses an HPLC finger-print establishing method of a small flower sabia japonica. The HPLC finger-print establishing method of the small flower sabia japonica has the advantages of convenience, stability, high precision and great repeatability; the kind and number of chemical components contained in the small flower sabia japonica can further be reflected more thoroughly by adopting the HPLC finger-print establishing method, and thus the overall description and evaluation of the quality of the small flower sabia japonica are further conducted. Detected small flower sabia japonica finger-print by using the HPLC finger-print establishing method includes more chemical components, the height proportion of all characteristic peaks are moderate, the base line is more stable, thedegree of separation and the peak shape are great, and the column efficiency is high.

Description

technical field [0001] The invention relates to a method for establishing an HPLC fingerprint of Qingfengteng chrysalis, belonging to the field of pharmaceutical technology. Background technique [0002] Traditional Chinese medicine fingerprint is a comprehensive and quantifiable means of identification. 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. Traditional Chinese medicine and its preparations are multi-component complex systems, so the evaluation of its quality should adopt a detection method that is suitable for it and can provide rich identification information. The type and quantity of chemical components, and then the overall description and evaluation of drug quality. On this basis, if the study of spectrum efficacy is furth...
