Description
Technical field
The present invention relates to a kind of extraction separation methods of tanshin polyphenolic acid B, belong to technical field of bioengineering.
Background technique
Radix Salviae Miltiorrhizae, Chinese medicine name.For the dry root and rhizome of Lamiaceae plant Radix Salviae Miltiorrhizae Salvia miltiorrhiza Bge..
Spring, the excavation of two season of autumn, silt is removed, it is dry.National most area is all distributed.It is inducing meastruation to relieve menalgia with promoting blood circulation, clear away heart-fire
The effect of relieving restlessness, cool blood to disappear carbuncle.For chest impediment and cardialgia, stomach duct and abdomen hypochondriac pain, a lump in the abdomen causing distension and pain, hot numbness pain, dysphoria and insomnia, and menstruation is not
It adjusts, dysmenorrhea menostasis, sore swell and ache curative.
In terms of being concentrated mainly on liposoluble constituent to the early stage research of effective component in red sage, more than 40 chemical combination have been obtained
Object.These compounds can be divided into two classes, i.e., tanshinone (o-quinone type) and enumerate ketone (adjacent hydroxyl paraquinoid).Tanshinone
Compound majority belongs to diterpene compound, and wherein most is diterpene quinone.Such as Tanshinone I, Tanshinone II -A, Radix Salviae Miltiorrhizae
II-B of ketone, tanshinone III, isotanshinone I, IsotanshinoneⅡ-A, Cryptotanshinone, different Cryptotanshinone, hydroxyl Tanshinone II -A, two
Hydrogen Tanshinone I, left-handed dihydrotanshinone I, neotanshinone A, neotanshinone B, neotanshinone C, new Cryptotanshinone II, ring phenol
The new Cryptotanshinone of lactamide, oleoyl and oleoyl danshenxinkun A etc..By the effort of decades, people are to fat soluble ingredient of red sage root
It obtains than more comprehensively recognizing, and important discovery is also achieved to the bioactivity research of various composition, it was demonstrated that these
The clinical application drug that a batch works well is developed in the pharmacological action of compound.Tanshin polyphenolic acid B is three molecule danshensus and one point
Sub- caffeic acid is combined into.Tanshin polyphenolic acid B is the highest water-soluble phenolic sour component of content in Radix Salviae Miltiorrhizae, is accounted in the pharmacological action of Radix Salviae Miltiorrhizae
There is critical role.But tanshin polyphenolic acid B is easily degraded, various catabolites have again in aqueous solution because its chemical structure is unstable
Complicated pharmacological activity.This not only brings very big difficulty to the preparation process of red sage root water soluble ingredient drug, and is possible to drop
The clinical efficacy of its low related preparations.
The damp and hot degradation of tanshin polyphenolic acid B meets first order kinetics in Salvia miltiorrhiza Bge water extract, and reaction rate constant is in heating temperature, pH
Positive correlation, wherein temperature is greater than the influence of pH to the influence of reaction rate constant K.Thus, when extracting separation tanshin polyphenolic acid B
The time that Radix Salviae Miltiorrhizae impregnates, water is mentioned, is concentrated and dried should be shortened, avoid long-time heating under alkaline condition, and will be as far as possible
The resting period for shortening solution state makes Salvia miltiorrhiza Bge water extract solidification that can reduce tanshin polyphenolic acid B loss as early as possible.In addition, should be as far as possible
Guarantee to save under low pH, high concentration and cryogenic conditions, to keep tanshin polyphenolic acid B stability in aqueous solution.
Currently, application of the biological enzyme in traditional Chinese medicine technology is further extensive, especially in the extraction process of Chinese medicine, obtain
Significant effect.Enzyme reaction needs certain condition.Under optimum conditions, active most strong, the catalytic capability shown of enzyme
It is most strong.
The present invention is intended to provide a kind of extraction separation method of the tanshin polyphenolic acid B of environment-friendly high-efficiency, tanshin polyphenolic acid B during the separation process
Stability is high, and degradation rate is low, and makes full use of biotechnology, environment-friendly high-efficiency.
Summary of the invention
The object of the present invention is to provide a kind of extraction separation methods of the tanshin polyphenolic acid B of environment-friendly high-efficiency, red during the separation process
Phenolic acid B stability is high, and degradation rate is low, and makes full use of biotechnology, environment-friendly high-efficiency.The structural formula of tanshin polyphenolic acid B is as follows:
Stevia is a kind of natural sweet taste of high sugariness for extracting from stevia rebaudian leaf non-nutritive low in calories
Agent.Currently, eight kinds of glucosides are had found from stevia, i.e. Stevioside (slevioside), rebaudioside
(RebaudiosideA, B, C, D, E), (Dul~ide ties up primary glucoside (steviobi~siti) Lai Baodi with this to Dul-A
The sugariness highest of glucoside A, greater than 300 times of sucrose, and taste matter is best, is free of any bad pleasant impression, is a kind of ideal
Crude sweet hides agent, and extraction prepares the research heat that the high stevia rebaudianum sugar product of content rebaudioside-A content is domestic and international stevioside production industry
Point
Stevioside (being commonly called as stevioside, steviol glycoside) is one kind from catananche's STEVIA REBAUDIANA (or stevia rebaudian leaf)
The new type natural sweetener that essence mentions, and South America uses STEVIA REBAUDIANA to have centuries history as medicinal herbs and for sugar.
The applicant for the first time applies to rebaudioside and stevioside in the extraction separation of tanshin polyphenolic acid B, with Lay Bao
Enlightening glucoside and stevioside can effectively shorten the time of enzymatic treatment, and also can protect tanshin polyphenolic acid B in purification process
Activity, thus the stability of the tanshin polyphenolic acid B during increasing substantially extraction purification.The two exclusive use has this effect, group
More there is synergy altogether.
Technical problems to be solved needed for the present invention can be achieved through the following technical solutions.
A kind of extraction separation method of tanshin polyphenolic acid B, its step are as follows:
(1) it chooses red rooted salvia: choosing the red rooted salvia medicine materical crude slice in accordance with States Pharmacopoeia specifications；
(2) it extracts: according to parts by weight, weighing 1 part of red rooted salvia medicine materical crude slice, 12 parts of water of pH5.0 are added, every gram of medicinal material is added
The zytase of 5-15U, rebaudioside and/or stevioside, 38-45 DEG C reaction 2-3 hours, it is cooling, filtered fluid is obtained by filtration；
(3) it purifies: 1/5th of the original volume of extracting solution vacuum concentration is purified using macroporous absorbent resin.
Preferably, the step (3) are as follows:
95% ethyl alcohol impregnates resin 18-20 hours, is swollen it sufficiently, selects glass column, is rinsed and is set using 95% ethyl alcohol
Rouge column washes away the organic impurities in resin containing band.The washing of first deionization, 5% hydrochloric acid solution impregnate, and drain acid solution, then spend from
Sub- water is cleaned, and 2-4% sodium hydroxide solution is added and washes, then deionization washing, removes water-solubility impurity in resin.Use 50% second
The HCL solution of alcohol rinses resin column.Extract loading is cleaned using a small amount of deionized water, and effective component is attracted to macroreticular resin
It is interior.With 50% ethanol-eluting resin column, the eluent of purifying is collected, solution is dried in vacuo, obtains product.
Advantages of the present invention:
(1) integrated use zytase of the present invention, rebaudioside and stevioside can effectively shorten enzymatic treatment when
Between, and also can protect in purification process the activity of tanshin polyphenolic acid B, thus the red phenol during increasing substantially extraction purification
The stability of sour B.The two exclusive use has this effect, and combining more has synergy.
(2) it directly from red rooted salvia medicine materical crude slice, does not need to crush, a step can be obtained the very high extracting solution of recovery rate.
