Embodiment 1

[0023] Embodiment 1: The construction of the stable nitrogen and hydrogen isotope fingerprints of part of Henan Daodi Chinese medicinal material Huai Yam is described below, and the method is described, and the concrete method steps are as follows:

[0024] 1. Procedure for the determination of stable nitrogen isotopes

[0025] 1. Sample collection

[0026] Due to the specificity of plant samples, every detail of sampling must ensure minimal error in the final assay results. When sampling plants, pay attention to the following issues:

[0027] (1) When sampling, in order to make the samples of traditional Chinese medicinal materials more representative, 5-10 individual plants of each species in each plot should be sampled separately, and then combined into one to form one of the species. sample.

[0028] (2) Since the isotopic fractionation of the N assimilation process in young plants and immature tissues has not been completed, 15 The natural abundance of N has not final...

Abstract

A method for identifying unadulterated traditional Chinese medicine based on stable isotope fingerprint specifically comprises the following steps: 1, firstly testing stable nitrogen isotope composition and proportion of unadulterated traditional Chinese medicine; 2, secondly testing stable hydrogen isotope composition and proportion of unadulterated traditional Chinese medicine; 3, thirdly constructing stable isotope fingerprint; 4, finally identifying unadulterated traditional Chinese medicine. The invention can fast, accurately and effectively identify the quality, origin place and adulteration of unadulterated traditional Chinese medicine with good popularization value.

Description

technical field [0001] The invention relates to a method for identifying authentic Chinese medicinal materials, in particular to a method for identifying authentic Chinese medicinal materials using stable isotope fingerprints. Background technique [0002] Chinese herbal medicine is an important resource in the treasure house of medicine in our country. Some valuable Chinese herbal medicines are favored by people because of their unique authenticity. However, in recent years, with the inclination of national policies on the production and deep processing of Chinese medicinal materials, the production of some authentic Chinese medicinal materials has been impacted, and the adulteration of authentic Chinese medicinal materials is serious, which directly affects the production and export trade of traditional Chinese medicine in my country. How to accurately and timely detect the quality, origin and adulteration of authentic Chinese medicinal materials is one of the key issues t...
