Abstract

The invention discloses a geo-authentic crude drug quality identification method based on multiple-spectral fusion. According to the geo-authentic crude drug quality identification method based on multiple-spectral fusion, ionic migration spectrum, Raman spectrum, and ultraviolet spectrum of traditional Chinese medicinal materials from different producing areas are collected; pattern recognition algorithm, including wavelet denoising, spectrogram normalization, kernel principal component analysis, and sparse classification algorithm, is adopted for fusion discrimination analysis of obtained multiple-spectral information. The geo-authentic crude drug quality identification method is capable of realizing rapid, accurate, and intelligent identification of traditional Chinese medicinal materials from different producing areas, increasing utilization rate of spectral information effectively, and increasing identification rate of geo-authentic crude drugs.

Description

technical field

[0001] The invention belongs to the technical field of medicinal material identification, and in particular relates to an authentic medicinal material quality identification method based on multispectral fusion. Background technique

[0002] Chinese medicinal materials are an important basis for the clinical efficacy of traditional Chinese medicine compounds, and Chinese medicinal materials from different origins are affected by various factors such as geographical location, climatic conditions, soil quality, temperature, humidity, etc., and then show different pharmacological effects and clinical efficacy. Taking Astragalus as an example, Astragalus is the dried root of the leguminous plant Astragalus mongolica or Astragalus membranaceus. It is a traditional Chinese medicinal material in my country. , mainly produced in Gansu, Inner Mongolia, Shanxi and many other provinces in China. However, in terms of clinical practice, the difference in the growth envir...
