Method for extracting radix codonopsis extract

Abstract

The invention discloses a method for extracting radix codonopsis extract. The method comprises the steps that one part of radix codonopsis is placed in a drying box, radix codonopsis is dried till the water content of radix codonopsis is smaller than or equal to 5%, and grinding is carried out; electronic beams with the strength being 10 kGy are used for irradiation; radix codonopsis powder is added into 70% ethyl alcohol with the pH value being 5, water bath ultrasonic treatment is carried out for 5 min, stirring is carried out for 1 h, suction filtration is carried out, first filtrate and first filter residues are obtained, the first filtrate is subjected to rotary evaporation, and a mixture A is obtained; the first filter residues are placed in eight parts of organic solvent, water ultrasonic treatment is carried out for 5 min, stirring is carried out for 30 min, suction filtration is carried out, second filtrate is obtained and subjected to rotary evaporation, and a mixture B is obtained; second filter residues are added into 50 parts of deionized water, digesting is carried out for 10 min, the mixture is cooled to 30 DEG C, suction filtration is carried out, third filtrate is obtained, reduced pressure distillation is carried out, and a mixture C is obtained; the mixture A, the mixture B and the mixture C are placed in 15 parts of absolute ethyl alcohol, the mixture is placed in a water bath at the temperature of 50 DEG C, stirring is carried out for 20 min, the mixture is placed in a refrigerator, the temperature is below 5 DEG C, standing is carried out for 10 h, suction filtration is carried out, liquid is filtered out, and the radix codonopsis extract is obtained. According to the method, nutrient substances in radix codonopsis are efficiently and safely extracted.

Description

technical field [0001] The invention relates to a method for extracting Codonopsis pilosula extract. Background technique [0002] With the development of our country's economy and the continuous improvement of people's living standards, people are paying more and more attention to their own health. Health care products are one of the foods that people use for daily health care. Among health food products, most health care products are extracted from plants. There are various kinds of products, but many plant-based extraction products need to consume a lot of raw materials, resulting in high prices. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the present invention is to provide a method for extracting Codonopsis pilosula extract, which can efficiently extract the nutrients contained in Codonopsis pi...
