Traditional Chinese herb odor discriminate method based on bionic olfaction and its device

Abstract

The invention relates to a traditional Chinese medicine material odor distinguishing method based on a simulating olfaction and a device thereof. The distinguishing method of the invention includes the following steps: 1) an odor tested object of traditional Chinese medicine material samples is prepared; 2) the odor fingerprint of the simulating olfaction method is established; 3) the odor fingerprint is standardized; 4) the odor fingerprint of the traditional Chinese medicine materials to be tested and the standard odor fingerprint are compared and a distinguishing result is obtained. The distinguishing device of the invention comprises an automatic injector, a metal oxidizing gas sensor array, a weak signal conditioning circuit, an analog-to-digital conversion circuit, a computer for information process and a monitor, wherein, the output end of the automatic injector is connected with the input end of the metal oxidizing gas sensor array; the output end of the metal oxidizing gas sensor array is connected with the input end of the weak signal conditioning circuit, the output end of the weak signal conditioning circuit is connected with the input end of the analog-to-digital conversion circuit, the output end of the analog-to-digital conversion circuit is connected with the input end of the computer for information process, and the output end is connected with the monitor. The traditional Chinese medicine material odor distinguishing method and the device thereof conform to the traditional medicine theoretical practicable method, and are convenient and practical.

Description

Technical field: [0001] The invention relates to a bionic sense of smell identification method for Chinese medicinal materials and a device thereof, and belongs to the innovative technology of a bionic sense of smell identification method for Chinese medicinal materials and a device thereof. Background technique: [0002] Traditional Chinese medicinal materials are the foundation of the development of traditional Chinese medicine, but for a long time, due to the lack of effective scientific detection means and analysis methods. As a result, Chinese medicinal materials in our country are still in a situation where varieties are confused and quality is difficult to be judged accurately. This not only seriously restricts the development of Chinese medicine in China, but also has become a bottleneck problem for my country's unique Chinese medicine to enter foreign markets. [0003] At present, the quality identification methods of Chinese medicinal materials mainly include chara...

AI Technical Summary

Problems solved by technology

[0006] The above methods for constructing fingerprints of Chinese herbal medicines all try to detect and analyze Chinese herbal medicines as a whole to evaluate the quality of Chinese herbal medicines, but they all have their own limitations. For example, chromatography has a common disadvantage, that is, it requires a long time for sample pretreatment. time, but the instrument operation is complicated, the analysis time is long, and it is difficult to directly link the obtained data with the smell of the material

The spectroscopic method is not only expensive, but also the data mining work needs to be developed, so it is difficult to popularize and apply at present

[0007] The above-mentioned technology has obtained certain application in the quality and variety identification of Chinese medicinal materials, but its detection object is not the smell of Chinese medicinal materials, which is completely separated from the most basic information characteristics of Chinese medicinal materials. The shackles of ingredient expression, and the current technical methods are not good for odor quality analysis, and it is impossible to analyze the quality of medicinal materials in general based on the theory and practice of traditional Chinese medicine.
