Embodiment Construction

[0020] combined with figure 1 , 2 Specific examples of the present invention are described.

[0021] 1. Use electrochemical methods to measure and record the spectral data of various herbal medicines.

[0022] (1) Take the first Chinese herbal medicine and grind it into a powder of ≥100 mesh;

[0023] (2) Weigh a certain amount of the above-mentioned Chinese herbal medicine powder and add it into a jacketed reactor with a stirring device, and then add a certain concentration of sulfuric acid (1.104mol / L), manganese sulfate (0.016mol / L), acetone (0.108mol / L) L) and potassium bromate (0.04mol / L) are sequentially added to the jacketed reactor, fully stirred at a temperature of 25°C ± 0.5°C for a chemical oscillation reaction to obtain a mixed solution;

[0024] (3) Open the inner layer device of the jacketed reactor and transfer the mixed solution into an electrochemical instrument with a redox electrode to start measuring and recording, and draw a reaction spectrum;

Abstract

The invention relates to a method for identifying Chinese herbal medicine by using electrochemistry. The method comprises the following steps: pulverizing Chinese herbal medicine into powder, adding to a mixture (a finite concentration) of sulfuric acid, manganese sulfate, acetone and potassium bromate, and completely stirring to carry out a chemical oscillating reaction, thereby obtaining a mixed solution; transferring the mixed solution to an electrochemical working instrument with an oxidation-reduction electrode, starting to measure and record, and drawing a reaction map; converting the reaction map into data by the electrochemical working instrument, recording and storing the data, thereby obtaining the map data of the Chinese herbal medicine; and changing the amount of the Chinese herbal medicine with the state of the chemical oscillator unchanged to obtain a series of data, drawing an amplitude-concentration curve chart, and qualitatively and quantitatively identifying the Chinese herbal medicine based on the chart which directly reflects the relationship between the amplitude and the concentration. The novel method for identifying Chinese herbal medicine is scientific and effective, has the advantages of simple operation and convenient mastery, and is beneficial to accelerating the modernization of the Chinese herbal medicine.

Description

technical field [0001] The invention relates to a method for identifying Chinese herbal medicines using electrochemistry. Background technique [0002] As we all know, there are many kinds of Chinese herbal medicines, and it is difficult to identify many Chinese herbal medicines from the aspects of plant shape, medicinal material shape, nature, taste, color, etc. Drug detection methods are not satisfactory for Chinese herbal medicines. The chemical information of Chinese herbal medicine is composed of the comprehensive factors of various chemical components. As far as Chinese medicinal materials are concerned, after more than a century of phytochemical research and pharmacological efficacy research, people have increasingly realized that the efficacy of Chinese herbal medicine does not come from any single active ingredient, but basically a variety of active ingredients, even It is a comprehensive result of "synergy" or "synergy" with inactive ingredients, monarchs and min...
