Problems solved by technology

This method uses salvianolic acid B as the reference to calculate the content of polyphenolic acid, and the specificity and accuracy are poor.
Moreover, for traditional Chinese medicine preparations with complex components, only one component is used to control the content index. While lacking integrity, the identification of complex components is not sufficient
[0006] Therefore, in view of the defects of insufficient identification and inaccurate quantification of the above-mentioned complex components,

Abstract

The invention relates to establishment of a salvianolic acid extract fingerprint spectrum and a content measurement method of related components. The content measurement method includes the following steps: 1) establishing the salvianolic acid extract digitized quantitative fingerprint spectrum through ultrahigh performance liquid multi-wavelength visible ultraviolet detection method; 2) recognizing peaks in the fingerprint spectrum in the step 1) with mass spectrum to determine common fingerprint peaks of ultraviolet detection; and 3) performing measurement to contents of three indicative components, which are high in content, significant in activity and definite in structure, recognized in the step 2) through high performance liquid chromatography variable-wavelength detection method.

Description

Technical field: [0001] The present invention relates to a detection method for extracts of traditional Chinese medicines, in particular to a method for establishing fingerprints of salvianolic acid extracts and determining the content of related components Background technique: [0002] Salvia miltiorrhiza is a plant of the genus Salvia in the family Lamiaceae. Also known as: Purple Salvia, Red Root, Blood Ginseng, Dahongpao, etc. The root of Danshen is used for medicinal purposes, it tastes bitter and slightly cold in nature. It has the functions of promoting blood circulation and regulating menstruation, removing blood stasis and promoting regeneration, calming the nerves, cooling blood and eliminating carbuncle, reducing swelling and relieving pain. It is used for the treatment of irregular menstruation, dysmenorrhea, postpartum stasis abdominal pain, joint pain, neurasthenia, insomnia, palpitation, carbuncle and sore. Modern medicine clinically proves that Salvia mil...
