Near infrared spectrum detection method for evaluating quality of medicinal material of gentiana straminea maxim

Abstract

The invention relates to the technical field of traditional Chinese medicinal material quality control and identification, in particular to a near infrared spectrum detection method for evaluating thequality of a medicinal material of gentiana straminea maxim. The method comprises the following steps of: processing a gentiana straminea maxim medicinal material sample and acquiring and processingnear infrared spectrum data; extracting gentiopicroside and loganic acid from the sample for content determination by means of high performance liquid chromatography, importing data and correspondingnear infrared spectrum data into software TQ Analysis, and establishing a model by taking the total amount of gentiopicroside and loganic acid as an evaluation index, and carrying out evaluation. Themethod can be used for simply, conveniently, quickly, accurately and efficiently detecting the quality of the medicinal material; when the sample points are arranged, a resource distribution area is wide in coverage, the sample size is large, and the collected samples are systematic, representative and different; related data of a target absorption peak can be rapidly extracted by adopting the infrared spectrum data extraction software, so that 2 / 3 of data extraction time is saved; and the method can ensure the most original information of the sample and reflect the interaction and overall relationship of the chemical components of the medicinal material.

Description

technical field [0001] The invention relates to the technical field of quality control and identification of traditional Chinese medicinal materials, in particular to a near-infrared spectrum detection method for quality evaluation of Gentiana twisted medicinal materials. Background technique [0002] Twist Gentiana ( Gentiana straminea Maxim. ) is Gentianaceae (Gentianaceae) Gentiana ( Gentiana ) Gentiana group ( Sect. ) is a perennial herb plant that is endemic to the Qinghai-Tibet Plateau. It is one of the four authentic medicinal materials of the Chinese herbal medicine Gentiana chinensis. The 2015 edition of the "Pharmacopia" stipulates that the decoction pieces of Gentiana chinensis are Gentiana chinensis ( Gentiana macrophylla Pall. ), Gentiana ( G. straminea Maxim. ), Gentiana thick stems ( G. crassicaulis Duthie ex Burk. ) or Gentiana ( G. dahurica Fisch. , also known as the dried root of Gentiana xiaoqin). It has the effects of dispelling rheumatism, ...

Problems solved by technology

[0003] Commonly used methods for quality testing of Chinese medicinal materials include high-performance liquid chromatography, ultraviolet-visible spectrophotometry, etc. These methods need to separate the mixture first, and then analyze the simple components or components. This is not only time-consuming and laborious, but also cannot guarantee The most original information of the sample cannot reflect the interaction and overall relationship of the chemical components of medicinal materials
