Background technology
Glutinous rehmannia (Rehmannia glutinosa Libosch) is scrophulariaceae (Scrophulariaceae) plant, also is the principal item of Chinese medicine, is the beneficial complementary class Chinese medicine of using always, and the beginning is stated from Shennong's Herbal.Glutinous rehmannia is divided into Rehmannia Root, Radix Rehmanniae and Radix Rehmanniae Preparata.That digs out annual September to October is Rehmannia Root, Rehmannia Root through cure or directly airing after water content is lower than 20%, become Radix Rehmanniae; Radix Rehmanniae is a Radix Rehmanniae Preparata through the wine steaming or after the stewed system of water.The main pharmacological of Rehmannia Root is heat-clearing, promote the production of body fluid, cool blood, appetizing etc.Radix Rehmanniae is heat-clearing, cooling blood for hemostasis etc.Radix Rehmanniae Preparata is a nourishing YIN and supplementing blood, and beneficial essence is filled out marrow etc.Because the Rehmannia Root preservation period is shorter, pharmacological action is similar with Radix Rehmanniae.
By now, found more than 60 kind of composition, but main functional component is glucoside material and glucide from glutinous rehmannia.Contain the 23 kinds of glucoside materials of having an appointment in the glutinous rehmannia, wherein based on iridoid glycosides.Glucide isolation identification has gone out 8 kinds, is respectively stachyose, raffinose, glucose, sucrose, fructose, mannotriose, verbascose and semi-lactosi.Other also contain amino acids material, mineral ion and trace element.
Contain various saccharides in the glutinous rehmannia, the wherein relevant stachyose that mainly contains with its effect, RPS-a (consisting of of glycogen: pectinose-rhamnosyl-glucose-seminose 4: 4: 2: 1), (consisting of of glycogen: semi-lactosi-glucose-wood sugar-seminose-pectinose 12: 6: 2: 2: 1), these glucides all can strengthen the immunization of human body to RPS-b.
But experiment is found, glutinous rehmannia is in the process of slaking, the total reducing sugar amount does not have significant difference (about 70%), after the stachyose that content is the highest in the glutinous rehmannia (reaching as high as 60%) is concocted, content obviously reduces (about 17%), and fructose (preceding 3.26% back 9.23%), glucose (preceding 1.56%, the back 8.57%) content of forming Dihuang polysaccharide RPS-a, RPS-b increase.Therefore glutinous rehmannia most polysaccharide in the process of concocting is converted into monose, if under the prerequisite of not destroying other compositions in the glutinous rehmannia, superfluous water threose in the Radix Rehmanniae is put forward with isolating method, the specific interpolation of surplus materials RPS-a, RPS-b, then can reach ripe glutinous rehmannia, this is a key point of the present invention.
Stachyose (Stachyose) is a kind of novel functional oligose, and more research has been done in its exploitation as functional foodstuff or pharmaceutical raw material at home and abroad.The stachyose structural formula is semi-lactosi-semi-lactosi-glucose-fructose, and molecular formula is C
24H
42O
21Molecular weight is 666.59, because connect with α-D-semi-lactosi glycosidic bond between glucosyl group and 2 semi-lactosis in its molecule, enzyme---the α-D-Ban Rutangganmei that lacks this key of hydrolysis in the human body, so it can not be absorbed by human consumption, the intravital most of flora of people does not have this kind of enzyme system yet, therefore can not utilize stachyose, only residing in minority probioticss such as bifidus bacillus in the enteron aisle and Lactobacterium acidophilum has this enzyme system, so stachyose has just become the specificity of these probioticss short biological.The stachyose efficacy factor is clear and definite, structure is clear, be described as third generation functional oligose, improving human gastrointestinal tract function, enhance immunity ability, preventing that cholesterol from raising, promoting that all many-sides such as mineral substance absorption, preventing dental caries all have many potential purposes.
Summary of the invention
The invention provides a kind of method of extracting stachyose and producing Radix Rehmanniae Preparata from Radix Rehmanniae, its summary of the invention mainly comprises the method for extracting stachyose from Radix Rehmanniae and the method for producing Radix Rehmanniae Preparata.
Now existing a plurality of patents have been mentioned the production method of stachyose, but it just puts forward the stachyose in the plant by variety of way, and remaining slag charge is not made full use of, so not only wasted resource, and polluted environment greatly, all costs all have been added among the stachyose, make the cost of stachyose high, and market competition does not have advantage.The characteristics of present method are not only to have extracted stachyose from glutinous rehmannia, and surplus materials processing has been reduced into Radix Rehmanniae Preparata, not only made full use of the natural resources of Chinese medicinal materials of this preciousness of glutinous rehmannia, and the cost of stachyose and Radix Rehmanniae Preparata is all significantly reduced, improved the market competitiveness of stachyose and Radix Rehmanniae Preparata greatly, through data-searching, also do not find similar extracting method, the present invention has the advance and the practicality of its uniqueness.
