A near-infrared spectroscopy detection method for the quality evaluation of Gentiana twisted medicinal materials

Abstract

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. The steps of the method are as follows: the processing of the Gentiana medicinal material sample and the collection and processing of the near-infrared spectrum data, extracting the gentiopicroside and loganinic acid in the sample to determine the content of the high-performance liquid chromatography, and the data and the corresponding near-infrared spectrum data Imported into the TQ Analysis software, the total amount of gentiopicroside and loganinic acid was used as the evaluation index for model establishment and evaluation. The method of the present invention can detect the quality of medicinal materials simply, quickly, accurately and efficiently; the resource distribution area covers a wide range of sample point layout, the sample size is large, and the collected samples are systematic, representative and differential; the infrared spectrum data extraction method adopted The software can quickly extract the relevant data of the target absorption peak, saving 2 / 3 of the data extraction time; this method can ensure the most original information of the sample, reflecting the interaction and overall relationship of the chemical components of the medicinal materials.

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
