A method for identifying traditional Chinese medicinal materials using hyperspectral data

Abstract

The invention relates to a method for identifying Chinese medicinal materials using hyperspectral data, comprising the following steps: (1) establishing a hyperspectral database of standard Chinese medicinal materials; (2) collecting hyperspectral data of Chinese medicinal materials to be inspected; The hyperspectral data of the Chinese medicinal materials are compared in the hyperspectral database of the standard Chinese medicinal materials, and it is determined according to the similarity of the hyperspectral data which Chinese medicinal materials the Chinese medicinal materials to be tested belong to. Preferably, the hyperspectral database includes the hyperspectral data of the standard Chinese medicinal materials. Spectral data information, the comparison operation in step (3) includes comparing the hyperspectral data information of the Chinese medicinal material to be tested with the hyperspectral data information of the standard Chinese medicinal material, and the hyperspectral database can also include the hyperspectral stability of the standard Chinese medicinal material Band area and characteristic peak information, hyperspectral data information of its characteristic active ingredients, etc., the present invention has ingenious design, accurate, rapid, reliable and simple detection, does not need to consume medicinal materials, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of Chinese medicinal materials, in particular to the technical field of identification of Chinese medicinal materials, and specifically refers to a method for identifying Chinese medicinal materials by using hyperspectral data. Background technique [0002] Traditional Chinese medicinal materials refer to medicinal materials produced in specific natural conditions and ecological environments. The production of traditional Chinese medicinal materials is relatively concentrated, and their cultivation techniques, harvesting and processing are also particular about them. Chinese medicinal materials are the main weapon for disease prevention and treatment. It plays a non-negligible role in protecting people's health and national reproduction. [0003] Therefore, the authenticity and quality of Chinese medicinal materials are directly related to the safety and efficacy of clinical medication. However, the confusio...

Problems solved by technology

[0006] However, in the actual process, the method of chromatographic separation of components has operational sensitivity and stability problems. In the identification process, it can only be judged by the peak height of one or a few compounds, which is different from the concept of active ingredient groups in traditional Chinese medicine. certain gap

However, existing spectral techniques can only scan the characteristics of Chinese herbal medicines in a single band, and it is difficult to fully reflect the comprehensive characteristic peaks of Chinese herbal medicines.

In addition, the existing technology often needs to dissolve Chinese medicinal materials, which cannot be recycled after detection, and Chinese medicinal materials need to be consumed and there is ambiguity in identification.
