Abstract
Description
technical field
[0001] The invention relates to a quality control method for Chinese patent medicines, in particular to a method for controlling the quality of Huoxiangzhengqi water by using high-performance liquid chromatography (HPLC) fingerprints. Background technique
[0002] Huoxiang Zhengqi Water is a commonly used medicine for relieving heat in summer. It is mainly composed of Huoxiang, Atractylodes atractylodes, Chenpi, Magnolia officinalis, Angelica dahurica, Poria, Dabupi, pinellia, licorice, perilla and other traditional Chinese medicines. Spasm, enhance cellular immune function and antibacterial effect.
[0003] Traditional Chinese medicine fingerprint refers to the chromatogram that can mark the chemical characteristics of some Chinese medicinal materials or preparations after proper treatment and certain analysis methods. Fingerprint of traditional Chinese medicine is a comprehensive and quantifiable means of identification. It is based on the systematic study...

Embodiment Construction
[0035] The present invention will be further described below in conjunction with specific embodiments, but it is not limited thereto.
[0036] A kind of quality control method of Huoxiang Zhengqi water, comprises the steps:
[0037]1) Preparation of the solution of the product to be tested: Take 300 μL of the product to be tested in Huoxiang Zhengqi Water, dilute to 1 mL with water, extract 3 times with ethyl acetate, take 2 mL of ethyl acetate each time, combine the extracts, and evaporate the acetic acid to dryness Ethyl ester, dilute to 10 mL with methanol, shake well, filter, and obtain;
[0038] 2) The product solution to be tested is carried out by high-performance liquid chromatography under the following chromatographic conditions to obtain the high polarity part fingerprint of the product to be tested:
[0039] Chromatographic column adopts Diamonsil C 18 ; Using gradient elution, mobile phase A is 0.05% formic acid aqueous solution, B is acetonitrile, C is methanol...
