Embodiment 1

[0031] A method for extracting and separating the root extract of Actinidia jujube, comprising the following steps:

[0032] S1: 12kg of soft jujube kiwifruit roots are dried in the sun to remove water, and crushed into granules with a grinder. Add 40L of 90% ethanol solvent. The solvent needs to cover the medicinal materials by about 10cm. Stir fully once every 2 hours, then take out the extract and concentrate to obtain the extract;

[0033] S2: add water to dissolve the extract obtained from S1, add ethyl acetate solvent 3 times the volume of the extract, perform 4 extractions, and combine all the ethyl acetate extracts. Recover under reduced pressure at 40°C and 0.09Mpa to obtain ethyl acetate extract.

[0034] S3: Use 100-200 mesh silica gel for the first step of coarse separation, air-dry the ethyl acetate extract sample and grind it into subdivisions, pass through a 100 mesh sieve, and then dry the sample, using a concentration gradient of 1: (100~ 1) Methanol: dichlo...

Abstract

The invention belongs to the technical field of plant extraction and analysis, and particularly relates to an actinidia arguta root extract as well as an extraction and separation method and application thereof. The extract comprises the following 21 chemical components: 21 chemical components; the invention discloses a preparation method of 7-O-[beta-D-xylose pyranosyl-(1-6)-beta-D-glucopyranoside]-1, 2, 4, 5, 6, 7-O-[beta-D-xylose pyranosyl-(1-6)-beta-D-glucopyranoside]-1. The preparation method comprises the following steps: preparing 2, 8-dihydroxy-3-methoxy-ketone; 3-O-[beta-D-rhamnose-(1-6)-beta-D-galactopyranoside]-5, 7, 3 ', 4'-tetrahydroxy flavone, catechin, beta-sterol, quercetin, isoquercitrin, oleanolic acid, ursolic acid, 2alpha, 3beta-dihydroxy oleanane-12 alkene-28 acid, 2alpha, 3alpha, 24-trihydroxy ursolic acid and the like. The extract provided by the invention has a good application prospect in preparation of anti-cancer drugs for improving the advanced living standard of cancer patients.

Description

technical field [0001] The invention relates to the technical field of plant extraction and separation, in particular to an extract of Actinidia jujube root, an extraction and separation method and an application thereof. Background technique [0002] Actinidia chinensis Planch, also known as "kiwi fruit", is a large deciduous vine. Because of its rich nutritional value, it is also known as the "king of fruits". There are many kinds of plants in the genus Actinidia, about 50 kinds. Now the widely spread on the market refers to the Chinese kiwifruit, and the kiwifruit of the Actinidiaceae is a plant of the genus Actinidia, which belongs to different species of plants with the Chinese kiwifruit. The root of Actinidia arguta (Sieb. et Zucc) Planch. ex Miq. In ancient times, the predecessors used the root of Actinidia jujube as medicine. Ancient books record that the root of Actinidia jujube has the effects of clearing away heat, cooling blood and diuresis. Modern studies hav...
