Abstract

The invention discloses a method for identifying walnut species by analyzing leaves based on gas chromatography-ion mobility spectrometry, and belongs to the technical field of plant species identification. The method comprises the following steps: obtaining a leaf sample of a walnut to be identified, performing liquid nitrogen treatment, and grinding the sample; analyzing volatile substances in the leaves by using gas chromatography-ion mobility spectrometry; and comparing the obtained volatile substance with a reference seed so as to obtain the walnut seed to be identified. According to the method, volatile substances such as terpenes, esters, aldehydes, alcohols and ketones in the walnut leaves are analyzed through gas chromatography-ion mobility spectrometry, a certain research basis is provided for development and utilization of walnut leaf resources, and technical basis and support are further provided for walnut seed identification.

Description

technical field [0001] The invention belongs to the technical field of plant variety identification, and in particular relates to a method for identifying walnut species based on gas chromatography-ion mobility spectrometry (GC-IMS) analysis of leaves. Background technique [0002] Walnut is one of the nuts we eat daily. Walnut is an angiosperm, dicotyledon, Juglandaceae, tree deciduous fruit tree, and is one of the world's four major dried fruits (almonds, walnuts, pistachios and hazelnuts). The walnut planting area in Xinjiang is large and the resources are very rich. The current research focuses on variety selection and cultivation management, while the pharmaceutical research only involves the anti-tumor activity of crude extracts of roots, pericarp or leaves. Branches, leaves, root bark, exocarp, nut inner septum and nuts of walnut can be used as medicine, and the curative effect on diseases is very high. Walnut leaves contain many kinds of nutrients, such as vitamins ...
