Abstract

The invention discloses a method and system for tracing the source of Chinese medicinal materials by using near-infrared spectral analysis. The detection method has the following steps: (1) Chinese medicinal materials are crushed and sieved; (2) near-infrared spectral images of Chinese medicinal material powder are collected; 3) According to the near-infrared spectrum of the collected catechu medicinal materials, input the established standard near-infrared spectral model, and calculate the content of the components to be tested in the Chinese medicinal materials; the spectral conditions of the near-infrared spectrum are: the number of scans is 30, the resolution 9cm ‑1 , taking the built-in background of the instrument as a reference, the scanning spectral range is 3500‑8000cm ‑1 . The method can directly determine the origin and quality of the measured sample without any separation of the sample, so it can be widely used in the quick and easy analysis of Chinese herbal medicines.

Description

technical field [0001] The invention mainly relates to the technical field of detection of traditional Chinese medicinal materials, in particular to a method and a system for tracing the source of traditional Chinese medicinal materials by using near-infrared spectral analysis. Background technique [0002] As one of the treasures of Chinese traditional culture, traditional Chinese medicine has made great contributions to the prosperity and life and health of the Chinese nation for thousands of years, and it has also gone through thousands of years of glorious history. Today, when modern medicine has covered the whole world, ancient Chinese medicine still shows strong vitality with its unique advantages. The rise of the global "green herbal medicine fever" and my country's entry into the WTO have brought great opportunities for ancient Chinese medicine to participate in international market competition. More than 120 countries or regions around the world have used Chinese he...
