Problems solved by technology

It is difficult to say that the purpose of controlling "quality" can be achieved through "quantity" in the content determination of some index components
Moreover, many index components are not unique to a certain medicinal material, and the specificity of controlling quality through a single index component is also poor

Embodiment 1

[0023] Embodiment 1: Analysis of self-made Shenmai liquid

[0024] (1) Determine the sample preparation method:

[0025] Using Extract-Clean C 18 (Alltech Associates, Inc, U.S.) small column to pretreat the sample, first rinse with 3ml of methanol, 3ml of water, and then accurately pipette 4ml of the sample into the pretreatment column, wash with 4ml of water, discard the washing solution, and then use 2ml 80% methanol eluted as the test solution.

[0026] (2) Acquisition of standard fingerprints:

[0027] Using reversed-phase high-performance liquid chromatography to obtain fingerprints that can characterize the chemical composition of the sample, see figure 1 . Chromatographic conditions Chromatographic column: Hanbang C 18 Column 4.6×250mm; mobile phase: A 0.01% acetic acid aqueous solution B acetic acid-water-acetonitrile 0.01:20:80; column temperature: 40; flow rate 0.5ml / min; detection wavelength: 202nm; elution gradient: linear elution. See Table 1.

Abstract

A quality control and evaluation method of traditional Chinese medicine is a method for controlling and evaluating the quality of traditional Chinese medicine by combining the fingerprint analysis method of traditional Chinese medicine with the content determination method of index components. Compared with the traditional method of judging the quality of traditional Chinese medicine based on the content of index components, the method for quality control of traditional Chinese medicine provided by the present invention has the advantage of reflecting the overall quality of the complex system of traditional Chinese medicine more exclusively, comprehensively and scientifically. Utilizing the new method for quality control of traditional Chinese medicines of the invention can formulate new quality standards for traditional Chinese medicine preparations including process characteristics, so as to achieve the purpose of protecting the varieties of traditional Chinese medicines produced by manufacturers. It can also conduct a comprehensive evaluation of the quality stability of traditional Chinese medicine.

Description

technical field [0001] The invention belongs to a method for quality control of traditional Chinese medicines, in particular to evaluating and controlling the quality of traditional Chinese medicines by means of combining fingerprint analysis and evaluation technology and index component quantitative detection technology. Background technique [0002] The records of Chinese medicine quality control methods in my country are the most comprehensive and earliest in the world. However, due to slow technological updates and backward quality analysis and evaluation methods, the current national quality standards for Chinese medicine are still far from perfect and cannot fully reflect the quality of Chinese medicine. , far from meeting the actual needs of the Chinese medicine industry. In the first part of the Chinese Pharmacopoeia of the 2000 edition, a total of 992 kinds of Chinese medicinal materials and Chinese patent medicine preparations have been recorded, 602 kinds of which ...
