Abstract

The invention provides a preparation method of medicinal chlorogenic acid, wherein the preparation method comprises the following steps: a, carrying out water phase treatment on a sample; b, freezing; c, thawing and filtering; d, carrying out organic phase treatment on the filter residue; e, concentrating and crystallizing; f, according to a difference of the contents of chlorogenic acid in the sample, selecting the repeating times of the a-e steps; and g, drying. A chlorogenic acid extract is separated and purified by the method, water-soluble impurities and fat-soluble impurities in the extract can be better removed, and thus the impurity content of the final product meets the medicinal requirements; at the same time, the method has the advantages of simple operation, recyclable organic solvent and low cost, is suitable for further separation and purification of a chlorogenic acid extract extracted by all kinds of methods, and is especially suitable for the preparation of the medicinal chlorogenic acid.

Description

technical field

[0001] The invention relates to a preparation method of medicinal chlorogenic acid. Background technique

[0002] Chlorogenic acid has a wide range of antibacterial effects, but it can be inactivated by proteins in the body. Similar to caffeic acid, it can increase the central excitability of rats when taken orally or intraperitoneally. It can increase the intestinal motility of rats and mice and the tension of rat uterus. Good choleretic effect, can enhance the secretion of bile in rats. It is sensitizing to humans, and after inhalation of plant dust containing this product, asthma and dermatitis may occur. At present, there are many separation and purification methods of chlorogenic acid reported, such as: application number: CN201010558366 Invention name: a production method for preparing chlorogenic acid by freezing and concentrating crystallization, the present invention discloses a production method for chlorogenic acid crystallization, which belongs...
