Problems solved by technology

When HPLC analyzes traditional Chinese medicine, its advantages are high column efficiency, good selectivity, wide application, etc., but there are also the following disadvantages: (1) The composition of traditional Chinese medicine is complex and unclear, which increases the difficulty of sample pretreatment, and It is easy to cause pollution and affect the life of the column; (2) the column efficiency of each column is actually less than 10,000 trays; (3) the consumption of solvent is large; (4) the analysis time is generally longer
However, so far, no literature and patent reports have been found in the fingerprint analysis of Chinese patent medicines by CE-ED method

Embodiment 1

[0033] Example 1: Quality analysis and identification of three different dosage forms of traditional Chinese medicines made from the herbal medicine Zhongjiefeng: compound grass coral buccal tablets, Qingrexiaoyanning capsules and Xuekang oral liquid

[0034] (1) The preparation of buffer solution, its concrete method is:

[0035] Direct mixing of NaH 2 PO 4 and Na 2 B 4 o 7 Aqueous solutions with concentrations of 7.0 and 7.5mol L -1 , pH value of 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0 solution with 0.20mol L -1 HCl or 0.20mol L -1 NaOH adjustment.

[0036] (2) Preparation of index component standard solution and cyclic voltammetry experiment, the process is as follows:

[0037] The herbal medicine Zhongjiefeng and three traditional Chinese medicines made from it: compound grass coral buccal tablets, Qingrexiaoyanning capsules and Xuekang oral liquid. -3 mol L -1 standard solution, and stored in a refrigerator at 4°C, diluted with secondary water to 1.0×10 before...

Embodiment 2

[0055] Example 2: Quality analysis and identification of the same Chinese medicine from different manufacturers

[0056] (1) The preparation of buffer solution, its concrete method is:

[0057] Direct mixing of NaH 2 PO 4 and Na 2 B 4 o 7 Aqueous solutions with concentrations of 7.0 and 7.5mol L -1 , pH value of 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0 solution with 0.20mol L -1 HCl or 0.20mol L -1 NaOH adjustment.

[0058] (2) Preparation of index component standard solution and cyclic voltammetry experiment, the process is as follows:

[0059] The index component in Xuekang Oral Liquid is isoferidin, dissolved in methanol to make 5.0×10 -3 mol L -1 standard solution, and stored in a refrigerator at 4°C, diluted with secondary water to 1.0×10 before use -5 mol L -1 .

[0060] Cyclic voltammetry experiment of the standard solution: first place a 33 μm CFE electrode in NaH 2 PO 4 and Na 2 B 4 o 7 The mixed solution was scanned for one week as a background. ...

Abstract

The present invention is quality analysis and identification method of herbal medicine material glabrous sarcandra herb and its three kinds of Chinese medicine preparation, compound glabrous sarcandrabuccal tablet, Qingrexiaoyanning capsule and Xuekang oral liquid. The method is one capillary electrophoresis-electrochemical analysis process, which includes the main steps of comparing the capillary electrophoresis-electrochemical analysis obtained fingerprints for the quantitative detection of the components, and identifying the Chinese medicine based on peak number, peak height and peak height ratio. The present invention has the advantages of high separation efficiency, low detection limit, low cost, high reproducibility, etc.

Description

technical field [0001] The invention relates to the quality analysis and identification method of herbal medicine sarcophagus and the traditional Chinese medicine made from it. Background technique [0002] Chinese medicine, including Chinese herbal medicine and its preparation Chinese patent medicine, is a precious wealth accumulated by Chinese people in the process of preventing and treating various diseases for thousands of years. Now, traditional Chinese medicine has attracted the attention of many international scholars because of its low toxicity, good curative effect and controllability. The good efficacy of traditional Chinese medicine is the result of the joint action of many chemical components in it, which is the essential difference between traditional Chinese medicine and high-purity chemically synthesized drugs. Therefore, it is difficult to evaluate the authenticity, quality, safety and efficacy of traditional Chinese medicine based on the analysis of only on...
