Embodiment 1

[0021] Example 1: Preparation of 2-O-cis-feruloyl-3-O-β-D-glucopyranose-β-D-glucopyranoside from the walnut green bark of Yangbi walnut tree

[0022] Step 1: get the walnut green skin of the Yangbi walnut tree (Juglans sigillata, another name three Taiwan bubble walnuts, tea bubble walnuts, deep texture bubble walnuts, iron walnuts, etc.) that is cleaned and dried in the shade, and cross 40 mesh sieves after crushing, and the mass ratio is Add 70% methanol aqueous solution at 1:2, extract at room temperature for 3 times, each time for 72 hours, filter, and concentrate the filtrate under reduced pressure to 4% of the original volume to obtain a crude extract;

[0023] Step 2: Add water with 3 times the mass of the crude extract, stir, add petroleum ether with 3 times the mass of the crude extract to extract 4 times, separate the petroleum ether layer, add ethyl acetate with 3 times the mass of the crude extract to the remaining water layer ester extraction 4 times, the ethyl ac...

Embodiment 2

[0032] Example 2: Preparation of 2-O-cis-feruloyl-3-O-β-D-glucopyranose-β-D-glucopyranoside from the walnut green bark of wild walnut tree

[0033] Step 1: Get the walnut green skin of the wild walnut tree (Juglans cathayensis Dode, another name hickory nut, Pakistan walnut etc.) that washes and dry in the shade, pass through 40 mesh sieves after pulverizing, be 1: 3 by mass ratio and add volume percent concentration to be 75 % methanol aqueous solution, ultrasonic-assisted extraction twice, each time for 1 hour, filtered, and the filtrate was concentrated under reduced pressure to 6% of the original volume to obtain a crude extract;

[0034] Step 2: Add water with 2 times the mass of the crude extract, stir, add petroleum ether with 4 times the mass of the crude extract to extract 3 times, separate the petroleum ether layer, add ethyl acetate with 4 times the mass of the crude extract to the remaining water layer The ester was extracted twice, the ethyl acetate layer was sepa...

Embodiment 3

[0037] Example 3: Preparation of 2-O-cis-feruloyl-3-O-β-D-glucopyranose-β-D-glucopyranoside from walnut green bark of walnut tree

[0038] Step 1: get the walnut green skin of the walnut tree (Juglans regia, having another name called Chinese walnut, common walnut etc.) that cleans and dry, cross 40 mesh sieves after pulverizing, be 1: 2.5 by mass ratio and add volume percent concentration and be 65% methanol aqueous solution, heated and extracted 4 times, each time for 12 hours, filtered, and the filtrate was concentrated under reduced pressure to 5% of the original volume to obtain a crude extract;

[0039] Step 2: Add water with 2 times the mass of the crude extract, stir, add petroleum ether with 3 times the mass of the crude extract to extract twice, separate the petroleum ether layer, add ethyl acetate with 3 times the mass of the crude extract to the remaining water layer The ester was extracted twice, the ethyl acetate layer was separated, and the ethyl acetate layer w...

Abstract

The invention belongs to the field of comprehensive utilization of high value-added chemical components in the resources of agricultural and forestry product processing residues, and specifically relates to cis-ferulic acid glycoside, namely 2-O-cis-ferulyl-3-O-beta-D-glucopyranosyl-beta-D-glucopyranoside, which has never been reported in the existing literature, and a preparation method thereof.The product is prepared by using walnut green husk of Juglandaceae Juglans L. trees as the raw material and by means of extraction, leaching, separation and the like. The preparation method of the invention has characteristics of efficient preparation process, simple operation, mild process condition, high product purity, high yield, etc.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of high value-added chemical components in agricultural and forestry product processing residue resources, and specifically relates to a cis-ferulic acid glycoside that has never been reported in the existing literature, that is, 2-O-cis-feruloyl- 3-O-β-D-glucopyranosyl-β-D-glucopyranoside (2-O-cis-feruloyl-3-O-β-D-glucopyranosyl-β-D-glucopyranoside) and a preparation method thereof. It is prepared by extracting, extracting, separating and other means from walnut green bark of Juglandaceae Juglans tree as raw material. Background technique [0002] Walnut green peel is the immature green peel residue left after walnut processing, which is a valuable reusable resource (Xiao Wangcheng, et al., China Animal Husbandry and Veterinary Medicine, 2019, 46(08): 2431-2437; Liu Di, et al. , Grain and Oils, 2019, 32(01): 89~92). my country is a big producer of walnuts, and a large amount of green wa...
