Embodiment 1

[0017] Embodiment 1: a kind of extraction method of burdock root aqueous extract, extraction method is as follows:

[0018] 1) Take 3500g of fresh burdock root, remove residual roots and impurities, wash, slice, add 6 times the weight of burdock root to boil, then simmer for 30 minutes, stir repeatedly, and filter to obtain a medicinal solution;

[0019] 2) Add 3 times the weight of water to the medicinal dregs obtained in step 1), boil, decoct with low heat for 30 minutes, and filter to obtain a secondary medicinal liquid;

[0020] 3) Merge the two filtrates, concentrate the filtrate to 1650ml with an electric furnace, and obtain a decoction with a concentration of 2g / ml;

[0021] 4) Filter the decoction obtained in step 3), filter out the solid content, concentrate and freeze-dry to obtain dry powder of burdock root extract with a yield of 4-7%;

[0022] 5) The obtained dry powder is determined by the phenol sulfuric acid method, and the dry powder of the burdock root extra...

Embodiment 2

[0024] A kind of extraction method of burdock root aqueous extract, extraction method is as follows:

[0025] 1) Take 3500g of dried burdock root, remove residual roots and impurities, wash, slice, add 8 times the weight of burdock root to boil, then simmer for 30 minutes, stir repeatedly, and filter to obtain a medicinal solution;

[0026] 2) Add 3 times the weight of water to the medicinal dregs obtained in step 1), boil, decoct with low heat for 30 minutes, and filter to obtain a secondary medicinal liquid;

[0027] 3) Merge the two filtrates, concentrate the filtrate to 1650ml with an electric furnace, and obtain a decoction with a concentration of 2g / ml;

[0028] 4) Filter the decoction obtained in step 3), filter out the solid content, concentrate and freeze-dry to obtain dry powder of burdock root extract with a yield of 4-7%;

[0029] 5) The obtained dry powder is determined by the phenol-sulfuric acid method, and the dry powder of the burdock root extract contains 98...

Abstract

The invention relates to a method for extracting a burdock root aqueous extract and application thereof. The extraction method comprises the following steps: burdock root is removed with impurities, is cleaned, is sliced, is added with water of 6 to 8 times of the weight of the burdock root, is decocted and is filtered to obtain a primary liquid medicine; medicine residue is added with water of three times of the weight of the medicine residue, is decocted and is filtered to obtain a secondary liquid medicine; two filtrates are mixed and condensed to form a water decocted liquid medicine with concentration of 2 g/ml; the water decocted liquid medicine is filtered with a solid content and is condensed, frozen and dried to obtain the dry powder of the burdock root extract; and the obtained dry powder of the burdock root extract contains 95 to 98 percent of amylose. The burdock root aqueous extract as a medicine raw material and a functional food raw material is respectively prepared into a capsule preparation, a troche, a powder preparation, a granule preparation, an oral liquid preparation or a compound preparation according to the prior preparation method. The burdock root aqueous extract can be used for preventing and treating male erectile dysfunction.

Description

technical field [0001] The invention relates to the extraction and application of a water extract of burdock root, belonging to the field of biotechnology. Background technique [0002] Male erectile dysfunction (Erectile dysfunction, referred to as ED) refers to the inability of the penis to erect, the erection is not firm or firm and not durable, so that the inability to have sexual intercourse; the definition made by the International Impotence Society is: the penis cannot be effectively erected during sexual intercourse, resulting in ineffective sexual intercourse. satisfy.
