Embodiment 1

[0028] 1) Lycium barbarum fruit pretreatment step Lycium barbarum fruit is first dried in an oven, taken out and placed in a drying room to stand for 24 hours, crushed and placed in an ordinary reflux device for degreasing, filtering out the solvent, and air-drying the residue for later use.

[0029] 2) The step of extracting Lycium barbarum polysaccharides uses ethanol as a solvent, and adopts an ultrasonic-assisted method. The extract is concentrated, alcohol-precipitated, and dried to obtain Lycium barbarum polysaccharide coarse powder; the process conditions are: the volume fraction of ethanol is 50%, and the ratio of solid to liquid is 1: 20. The extraction time is 50 minutes, and the number of extractions is 2 times;

[0030] 3) The step of extracting chlorogenic acid from Lycium barbarum extracts the residue after extracting Lycium barbarum polysaccharides, using ethanol as a solvent, extracting chlorogenic acid from Lycium barbarum by ultrasonic-assisted method, separat...

Abstract

The invention relates to a chlorogenic acid extractive technique, in particular to a method for extracting chlorogenic acid from Chinese wolfberry. The method for extracting the chlorogenic acid from the Chinese wolfberry comprises the following steps of: 1) preprocessing the Chinese wolfberry; 2) extracting wolfberry polysaccharide; and 3) extracting the chlorogenic acid from the Chinese wolfberry. The method has the advantages that: the invention relates to the method for extracting the chlorogenic acid from the Chinese wolfberry taking leftovers of the enterprise production, namely Chinesewolfberry residues as a raw material; and the method has low extraction cost and short time, extends a Chinese wolfberry industrial chain, increases the added value of the Chinese wolfberry product, and realizes the optimized configuration of the raw material. According to the method, ultrasonic extraction is adopted so as to generate strong vibration, high acceleration and great cavitation and stirring action; when the method is used for auxiliary solvent extraction, the chlorogenic acid is accelerated to enter the solvent so as to shorten the extraction time, save the solvent and prevent the decomposition of the chlorogenic acid because of high temperature. The method for extracting the chlorogenic acid from the Chinese wolfberry provides the excellent production raw material for the related enterprises which develop and produce the medicament and the health food having the effects of preventing and curing tumor, reducing blood sugar, protecting the liver and gallbladder. The chlorogenic acid has the effects of increasing fragrance and protecting color, and can be used for food fresh keeping and various health foods and drinks.

Description

technical field [0001] The invention relates to a technology for extracting chlorogenic acid, in particular to a method for extracting chlorogenic acid from wolfberry. Background technique [0002] Chlorogenic acid is a kind of phenylpropanoid synthesized by plants in the process of aerobic respiration, and its molecular formula is C 16 h 18 o 9 , the molecular weight is 345.30. It is one of the main active ingredients of many Chinese herbal medicines such as honeysuckle, Eucommia, capillary, etc., and is also an important active ingredient in many fruits and vegetables. [0003] Chlorogenic acid has various functions such as scavenging free radicals, antibacterial and anti-inflammatory, anti-virus, hypoglycemic, lipid-lowering, liver-protecting and gallbladder-protecting, etc. Especially in recent years, it has been found that chlorogenic acids have anti-cancer and anti-AIDS effects, and can be used as Leading the design and development of anti-cancer and anti-AIDS drug...
