Embodiment 1

[0025] ①, ferment, take 1000g of the Chinese herbal medicine of genus chinensis, crush it through a 20-mesh sieve, add water to infiltrate the syringa vine powder, and ferment for 7 days at a temperature of 20-40°C to obtain a fermented product;

[0026] ②, extract the extract, add 10 times the amount of ethanol solution with a concentration of 50% to the fermented product, soak at room temperature for 48 hours, then heat and reflux to remove and recover the ethanol, leave the remaining liquid to stand and filter to remove slag, and filter The solution was concentrated under reduced pressure to obtain 235 g of extract whose relative density was 1.04;

[0027] ③, Acid hydrolysis, adding 2 equivalents of dilute sulfuric acid with a concentration of 1mol / L to the extract, stirring and hydrolyzing at 100±5°C for 5 hours, cooling, and centrifuging to obtain a precipitate;

[0028] ④, purification: i), add dilute hydrochloric acid to the precipitate obtained in the above step ③ to a...

Embodiment 2

[0030] ①, ferment, take 1000g of the Chinese herbal medicine of trachophyllum, crush it into a 20-mesh coarse powder, add dilute sulfuric acid water with a concentration of 1mol / L to infiltrate the trachophyllum powder, and ferment for 6 days at a temperature of 20-40°C to obtain a fermented product;

[0031] ②, extract the extract, add 8 times the amount of ethanol solution with a concentration of 70% to the fermented product, soak at room temperature for 36 hours, then heat and reflux to remove and recover the ethanol, leave the remaining liquid to stand and filter to remove slag, and filter The solution was concentrated under reduced pressure to obtain 265 g of extract whose relative density was 1.03;

[0032] ③, Acid hydrolysis, add 3.5 equivalents of dilute hydrochloric acid with a concentration of 1mol / L to the extract, stir and hydrolyze at 100±5°C for 3 hours, cool and centrifuge to obtain a precipitate;

[0033] ④, purification: i), add dilute sulfuric acid to the pre...

Embodiment 3

[0035] ①, ferment, get 1000g of the Chinese herbal medicine of trachophylla, pulverize it into a 20-mesh coarse powder, add 7% glucosidase of the weight of the meal and a certain amount of water to infiltrate the trachovine powder, and ferment for 5 days at a temperature of 20-40°C to obtain fermented product;

[0036]②, extract the extract, add 9 times the amount of methanol solution with a concentration of 80% to the fermented product, soak at room temperature for 24 hours, then heat and reflux to remove and recover ethanol, leave the remaining liquid to stand and filter to remove slag, and filter The solution was concentrated under reduced pressure to obtain 287g of extract whose relative density was 1.04;

[0037] ③, Acid hydrolysis, add 1 equivalent of dilute nitric acid with a concentration of 1mol / L to the extract, stir and hydrolyze at 100±5°C for 8 hours, cool and centrifuge to obtain a precipitate;

[0038] ④, purification: i), add dilute nitric acid to the precipit...

Abstract

The invention relates to the ligninoglycosides distilling material of the caulis trachelospermi and the distilling process. The overall distilling material includes the trachelosperogenin, the nortrachelosperogenin, the arctigenin and the matairesinol, the said four genins account for the exceeding eighty percentage of the overall distilling material. The producing process of distilling the ligninoglycosides overall distilling matetial from the caylis trachelosperogenin includes the ferment, the distilling and the dipping in the cream, translating the ligninoglycosides in the cream into the genins by the method of dispelling or enzyme melting, producing the coarse article of the ligninoglycosides and the purification. The invention is easy to produce and to handle. The cost is low. The output and the chief content of the efficient ingredient are improved greatly using the acid melting and the enzyme melting. So the invention provides a craftwork fitting for the industrialized producing of distilling the ligninoglycosides from the nature plate trachelospermi.

Description

technical field [0001] The invention relates to a kind of sugar derivatives extracted from natural plants, in particular total lignan aglycon extracts extracted from scorpion vine and its extraction process. Background technique [0002] It is a cane with leaves of the plant Apocynaceae, which has the functions of dispelling wind and dredging collaterals, cooling blood and reducing swelling. The ingredients contained in the vine are very complex, including lignans, flavonoids, triterpenoid saponins, violet derivatives, and compounds such as phenols, alcohols, and alkaloids. One of the more abundant ones is diphenylbutyric acid lactone lignans, which are mainly composed of stethroside and stethrosidegenin, nortoshiroside and nortoshigenin, arctiin and arctigenin and Composition of mogroside and mogroside. The general formula of the molecular structure of its glycosides and aglycones is as follows: [0003] R 1 =glc,R 2 =CH 3 , R 3 =OH talcosi...
