Description
Technical field
It is specially a kind of to be planted with Cruciferae the present invention relates to a kind of extraction separation of active principle in biological chemical field
Species is the extraction separation method that raw material prepares glucosinolate.
Background technology
The plant of Cruciferae is to be widely believed that a kind of plant with anti-cancer function at present.This is primarily due to cruciate flower
The plant of section contains a large amount of glucosinolate (glucosinolates, abbreviation GLS), and glucosinolate is the one of plant
Kind sulfur-bearing secondary metabolite, at present it has been found that more than 120 kinds of glucosinolate in plant.Glucosinolate is water-soluble
The ionic compound of property, non-volatility, thermal stability.If damaged, thio heteroside glycosylhydrolase, i.e. mustard occur for plant cell
Sub- sulphur thuja acid enzyme (myrosinase, thioglucoside glucohydrolase;EC3.2.3.1 it) is released, and water
Glucosinolate is solved, generates disulfate, glucose and a series of aglucones, these aglucons are by intramolecular
Rearrangement forms isothiocyanates, thiocyanates, nitrile and a small amount of epithio nitrile.Currently, there is many researchs to have shown that isothiocyanic acid
Ester has good anticancer effect and antioxidation, also generates different sulphur cyanogen some researches show that glucosinolate is metabolizable in vivo
Acid esters then plays its anticancer, anti-oxidant and antibacterial action.In recent years, studying more glucosinolate both at home and abroad includes
The glucorphanin in glucose sulforaphane (glucophanin, abbreviation GRA), radish seed in broccoli seed
(glucophenin, abbreviation GRE) etc..Glucosinolate basic structure is as follows:
The extracting method of glucosinolate is mainly hot formulation at present, and the solvent used includes ethyl alcohol, methanol, water and alcohol
Water mixed solution etc. has investigated influence of the factors such as temperature, solid-liquid ratio, time to extraction efficiency;The separation of glucosinolate
Purification process is mainly extraction, acidic alumina method and ion-exchange-resin process etc..It is verified, it is carried using containing alcoholic solvent
It takes, glucosinolate recovery rate is relatively low and cost is higher;It is purified, is introduced using acidic alumina or ion exchange resin
A large amount of salt, desalting process is complicated and the rate of recovery is relatively low.Application No. is 201210166482.9 Chinese invention patent application public affairs
A kind of method that glucosinolate is extracted in the cauline leaf waste from broccoli is opened, this method is by raw material through 75 DEG C of water-bath enzyme deactivations
Afterwards, 75% methanol aqueous solution extraction glucosinolate is used for multiple times, then sulphur glycosides is purified using anion exchange, is gone out
Enzyme is not thorough, and experiment is complicated, and cost is higher.Application No. is the Chinese invention patent applications of 2015104107303.X to disclose one
The method of the extraction of seedling stem sulphur mustard glucosinolate, this method by after the enzyme deactivation of raw material drying, grinding and ether defatting, by
Ultrasonication extracts glucosinolate using methanol aqueous solution, and then uses ethyl acetate removal of impurities and anion exchange
Purifying resin, purification process is extremely complex, and energy consumption is higher, and recovery rate is only 65%-75%, and uses methanol, ether, acetic acid second
The toxic reagents such as ester.
Invention content
It is an object of the invention to establish glucosinolate extraction and purification process method efficient, environmentally friendly, simple for process.
Using crucifer seeds as raw material, clasmatosis is realized by the method for crushing, to improve the molten of glucosinolate
Out-degree;Glucosinolate is extracted using the method for extracting in boiling water, extracting in boiling water can both make the sources Inner myrosin deactivation also can be into
One step promotes clasmatosis, recovery rate to be extracted more compared with alcohol water;It is absorption with Aqueous extracts using 10% ethanol water as eluent
Stoste purifies glucosinolate using activated carbon adsorption elution method, improves glucosinolate product purity to 2.5-3.0
Times, the glucosinolate rate of recovery is up to 85% or more obtained by entire technological process.
The thioglucose glycoside extraction separation technique method that the present invention is established, extraction efficiency is high, purification effect is good, technique
Simply, environmentally protective, it is suitable for the production and processing of the glucosinolate of food-grade and health care grade, before there is good popularization
Scape.
