Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] The purpose of the present invention is to provide a classification method and system for Astragalus seeds, which uses gas chromatography-ion mobility spectrometry to detect the samples to be tested. The samples do not need to undergo complicated pretreatment before detection, which saves a lot of labor and can quickly detect different types. Astragalus seeds, the detection method of gas chromatography-ion mobility spectrometry has high resolution and se...

Abstract

The invention provides an astragalus membranaceus seed classification method and system, and belongs to the technical field of traditional Chinese medicine identification. According to the method and system, astragalus membranaceus seed samples in an astragalus membranaceus seed database are subjected to gas chromatography-ion mobility spectrometry detection to obtain a feature sample set; the samples do not need to be subjected to complex pretreatment before being detected, so that a large amount of labor force is saved; the gas chromatography-ion mobility spectrometry detection method is high in resolution ratio and sensitivity, so that the detection efficiency is improved; according to the feature sample set and corresponding astragalus membranaceus seed types, iterative training is performed on a multi-layer sensor to obtain an astragalus membranaceus seed classification model; astragalus membranaceus seeds to be classified are detected, so that features to be classified can be obtained; and based on the astragalus membranaceus seed classification model, the astragalus membranaceus seeds to be classified are classified according to the features to be classified, the categories of the astragalus membranaceus seeds to be classified are determined, and the accuracy of astragalus membranaceus seed type discrimination is improved.

Description

technical field [0001] The invention relates to the technical field of identification of traditional Chinese medicines, in particular to a method and system for classifying astragalus seeds. Background technique [0002] Astragalus is a polymorphic group with a wide variety and great variation. There are more than 2,500 species in 11 subgenuses in the world. They are mainly distributed in the temperate regions of the northern hemisphere and South America, and are also widely distributed in Central Asia and West Asia. Our country is rich in Astragalus plant resources, the common ones are Astragalus mongolica, Astragalus membranaceus, Urad Astragalus of the subgenus Astragalus tufts, Astragalus Qinling of the subgenus Astragalus, Astragalus yunnanensis, etc. Astragalus membranaceus of the subgenus Astragalus, etc., "Chinese Pharmacopoeia" 2015 edition, included the first two kinds, namely Astragalus mongolica and Astragalus membranaceus. From the description of the properties ...
