Problems solved by technology

Metabolomics analysis based on nuclear magnetic resonance has the advantages of simple sample preparation, good repeatability, short analysis time, and the ability to detect various polar compounds at the same time. This method has been successfully applied to the analysis of many traditional Chinese medicines, but only donkey-hide gelatin Two kinds of animal drugs, donkey skin and donkey skin, use this analysis method

Embodiment example 1

[0072] This implementation case involves a 1 The method of H-NMR metabolomics identification of fresh velvet and hot-fried velvet, the steps included in the method are as follows:

[0073] Step 1: Take fresh Ergang velvet and burn it with alcohol lamp to remove the hair, cut it into 2 parts longitudinally, wrap the section with plastic wrap for 1 part, and use it for traditional hot processing, and 1 part as a fresh product.

[0074] The traditional thermal processing method is: put the wrapped velvet antler into boiling water for boiling and frying for 5 times in total, 1 minute each time; after each frying and frying, insert a 16-gauge needle connected with nitrogen gas into the tip of the wrapped velvet antler. Drain the blood, boil for the fifth time and put it in an oven at 70°C to bake for 8 hours, take it out and cut it into small pieces, wash it with water 5 times, and set it aside.

[0075] Step 2, weighing 20 g of velvet antler sample, crushing the tissue with 10 ti...

Abstract

The invention relates to a method of metabonomically identifying fresh corn cervi pantotrichum and heat-fried corn cervi pantotrichum based on 1H-NMR and belongs to the technical field of identification of traditional Chinese medicines. A fresh corn cervi pantotrichum product and a processed product are identified through a multivariate data processing mode by researching the chemical compound difference of fresh corn cervi pantotrichum and heat-fried corn cervi pantotrichum by applying a metabonomic technology of 1H-NMR. Compared with an existing corn cervi pantotrichum identification technology, the method provided by the invention has obvious advantages: metabolites of corn cervi pantotrichum are illustrated integrally, and difference among the metabolites can be compared systematically; by means of progressive PCA, PLS-DA and OPLS-DA layer by layer, the accuracy of an experimental result is ensured; the experimental result can be stable and controllable by means of rich nuclear magnetism data combined with modern high-tech analyzing software, so that the method has macro accuracy and micro precision. The method is also simple, convenient, rapid and economic and suitable for universality and simplicity of market and common individual applications.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine identification, in particular to a method based on 1 A method for the identification of fresh velvet and hot-fried velvet by H-NMR proton nuclear magnetic resonance spectroscopy metabolomics technique. Background technique [0002] Deer antler is a traditional precious Chinese medicine, which is the unossified and densely hairy young horns of the male deer Cervus nippon Temminck or the red deer Cervus elaphus Linnaeus. As a traditional clinical medicine, velvet antler has a history of thousands of years in our country. The 2015 edition of "Chinese Pharmacopoeia" records that velvet antler is sweet in taste and warm in nature, strengthens kidney yang, nourishes essence and blood, strengthens muscles and bones, regulates Chong and Ren, and relieves sores. Modern pharmacological studies have shown that deer antler has various pharmacological effects. It can protect myocardial d...
