Embodiment 1

[0033] The method for establishing the model for identifying the years of storage of leaves of Artemisia argyi comprises the following steps:

[0034] S1. Artemisia argyi sample pretreatment:

[0035] Artemisia argyi leaf samples were collected around the Dragon Boat Festival from 2014 to 2018 in Fudao Town, Tangyin County, Anyang City, Henan Province according to the "Z" sampling method, and were identified as Artemisia argyilevl.et Vant. by Associate Professor Huang Xianzhang of Nanyang Institute of Technology.

[0036] The samples of Artemisia argyi leaves of different years were removed, selected, cut into pieces, mixed well and set aside;

[0037] S2, preparing the Artemisia argyi sample extract:

[0038] Take the Folium Artemisiae Argyi sample, add ethyl acetate according to the solid-liquid ratio of the Folium Artemisiae Argyi sample and ethyl acetate as 1g:100mL, after extraction, filter, and the filtrate is the Folium Artemisiae Argyi sample extract;

[0039] S3. UV...

Embodiment 2

[0047] The establishment method of the model for identifying the year of storage of Folium Artemisiae Folium in this embodiment is the same as that in Example 1, except that the solid-liquid ratio of the Folium Folium Artemisiae Argyi sample to ethyl acetate is 1g:50mL.

Embodiment 3

[0049] The establishment method of the model for identifying the year of storage of Artemisia argyi in this embodiment is the same as that in Example 1, except that the solid-liquid ratio of Artemisia argyi samples to ethyl acetate is 1g:80mL.

Abstract

The invention relates to the technical field of medicinal material detection, in particular to a model for identifying the storage year of mugwort leaves, a building method and a method for identifying the storage year of mugwort leaves. The present invention uses ultraviolet-visible-near-infrared spectra to analyze the ethyl acetate extracts of Artemisia argyi samples in different years, and selects bands with little interference and differences in the spectra as variables to form a data matrix, and conducts a preliminary analysis of the ethyl acetate extracts of Artemisia argyi in different years. Classify and identify, and rename the spectral data of the extracts of Artemisia argyi in different years, and substitute them into SIMCA software for PLS-DA analysis, and obtain a PLS-DA model. The ethyl acetate extracts of Artemisia argyi samples in different years are in the PLS-DA model The regions of distribution are different. The exploration and establishment of the inventive method provides new technologies and methods for the quality control and storage year identification of Artemisia argyi.

Description

technical field [0001] The invention relates to the technical field of medicinal material detection, in particular to a model for identifying the storage year of mugwort leaves, a building method and a method for identifying the storage year of mugwort leaves. Background technique [0002] Artemisia argyi Levl. et Vant. is the dried leaf of Artemisia argyi Levl. et Vant., a herb of the genus Artemisia in the family Asteraceae. It is warm in nature, pungent, and bitter in taste. Artemisia argyi mainly contains chemical components such as volatile oils, flavonoids, tannins, triterpenoids, and eucalyptols, and has pharmacological effects such as antifungal, antiviral, antitumor, inhibiting platelet aggregation, and antitussive and antiasthmatic. Artemisia argyi is widely distributed in my country, except for extremely arid and alpine regions, almost all over the country, mainly produced in Hubei, Henan, Anhui, Hebei and other provinces. In recent years, the rapid development o...
