Problems solved by technology

There are still two outstanding problems in this type of test method: 1. The detection cost is high, and it is not suitable for the wide application of enterprises
2. These methods are aimed at the analysis and detection of certain components in hide glue from different animal sources. This method of comprehensive quality control of donkey-hide gelatin based on the analysis indicators of several components is very easy to provide unscrupulous traders with advantages. machine
At present, there are relatively few analytical applications for the rapid identification of donkey-hide gelatin and hide glue medicinal materials from different animal sources based on chemical oscillation fingerprint technology.

Abstract

The invention provides a method for identifying gum medicinal materials based on a chemical oscillation fingerprint technology, and the method comprises the following steps of: (1) adding the gum medicinal materials into an acid solution for acid hydrolysis, adding an oscillation system solution into the acid solution after the acid hydrolysis is completed, uniformly mixing the substances, and then communicating the mixed solution with an electrochemical workstation through an electrode, thus obtaining a chemical oscillation fingerprint spectrum; (2) carrying out pretreatment and characteristic parameter extraction on the chemical oscillation fingerprint spectrum, and carrying out principal component analysis and / or system similarity analysis; and (3) establishing a regression relationship between the characteristic parameters and the content of the gum medicinal materials. The method for identifying the gum medicinal materials based on the chemical oscillation fingerprint technology has the characteristics of simple test steps, rich characteristic parameters, high sensitivity, low detection cost and the like, and a new method is provided for identification and analysis of the gum medicinal materials.

Description

technical field [0001] The invention belongs to the technical field of donkey-hide gelatin detection, and in particular relates to a method for identifying gelatin medicinal materials based on chemical oscillation fingerprint technology. Background technique [0002] Donkey-hide gelatin is a solid gelatin made from dried skin or fresh skin of equine animal donkey, decocted and concentrated with more than a dozen kinds of auxiliary materials such as rice wine and soybean oil. The main components of donkey-hide gelatin include proteins, polypeptides, amino acids and trace elements, etc. Modern pharmacological studies have shown that donkey-hide gelatin has pharmacological effects such as anti-fatigue, hypoxia resistance, and immunity enhancement, and is sought after by a large number of consumers. [0003] The large demand for donkey-hide gelatin by consumers is seriously inconsistent with the growth rate of the number of donkeys, which intensifies the chaos in the market for ...
