Description
Technical field
The invention belongs to the field of Chinese medicines, be related to effective ingredient in Chinese and its extraction, purifying and process for purification, refer specifically to it is a kind of from
Hydrolysis kinetics gypenoside and preparation method thereof in gynostemma pentaphyllum herb raw material.
Background technology
Prior art discloses gynostemma pentaphylla herbaceous plant, also known as seven leaf courages, five are climbed up by holding on to for Curcurbitaceae gynostemma pentaphyllum genus are perennial
Ye Can, public arched bottom, take root with gynostemma pentaphyllum makino etc., Latin literary fame is Gynostemmapentaphyllum (Thunb.)
Makino.The plant is divided into 13 kinds, is distributed in China, Japan and Korea and Southeast Asian countries, wherein, show according to investigations,
There are 11 kinds of presence in China, i.e.,：Single leaf gynostemma pentaphyllum, G. laxum, Burma gynostemma pentaphylla, hair gynostemma pentaphylla, longstipe gynostemma herb, peck fruit
Gynostemma pentaphylla, heart seed gynostemma pentaphylla, small seed gynostemma pentaphylla, poly- fruit gynostemma pentaphylla, flower thinning gynostemma pentaphylla；Its bitter, property are sweet cold, nontoxic, with clear
Thermal detoxification, tonifying Qi promote the production of body fluid, expelling phlegm and arresting coughing, the effect for controlling nocturnal emission with astringent drugs of calming the nerves, cure mainly chronic bronchitis, cough, asthma, infectiousness liver
The diseases such as inflammation, pyelonephritis, and forgetful insomnia, burnout are eaten less, emission.
Contain saponins material, Flavonoid substances, polysaccharose substance, vitamins thing in studies have shown that gynostemma pentaphylla plant
The active ingredients such as matter, mushroom class class material, organic acid substance, alkaloids substance, protein substance.Saponins material is it
One of main component, gypenoside contains ginsenoside identical tetracyclic triterpene dammarane type structure.Saponin(e contains in gynostemma pentaphylla
Measure and relatively enrich, the priority separation from gynostemma pentaphylla of relevant research at present identifies more than 80 and plants saponin(e.Studies have shown that gynostemma pentaphylla
Saponin(e has reducing blood lipid, norcholesterol, hypotensive, enhancing coronary artery and cerebral blood flow (CBF), anti-DNA variation effect, raising machine
Body immunity function etc. is acted on.
At present, the general extraction methods for saponins material being extracted from Gynostemma pentaphyllum add water to cook method, organic solvent
Reflux extraction, percolation etc., and have the various new technologies such as Microwave Extraction, ultrasonic extraction, enzyme assisted extraction；But it is therein
Refined method is few, the main characteristic big using saponins material solubility in n-butanol, with extracting n-butyl alcohol, but positive fourth
Alcohol boiling point is high, and recovery is not easy, and residual quantity is larger in end-product, and industrialized production is difficult.
Present situation based on prior art, present inventor intends providing a kind of effective ingredient in Chinese and its extraction, purifying
And refined method, Hydrolysis kinetics gypenoside and preparation method thereof especially from gynostemma pentaphyllum herb raw material.This method will
There is realistic meaning to industrialized production Hydrolysis kinetics gypenoside.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of effective ingredient in Chinese and its extraction, purifying and refined side
Method, and in particular to gypenosides and preparation method thereof, especially one kind can industrialized production, cost is low, and technological process is short
The method of extraction purification gypenosides from gynostemma pentaphylla.
The present invention solves the technical scheme that is used of above-mentioned technical problem to be that a class is free of exchange base based on macroporous absorbent resin
Group and the preparation for having macroporous structure, with good macroreticular structure and larger specific surface area, and, greatly
Macroporous adsorbent resin is more and more applied to Chinese medicine and natural drug active ingredient, the purifying of active component and separated, and, it is described
Macroporous absorbent resin it is renewable reuse, the characteristics of production cost is low there is provided one kind from gynostemma pentaphylla Hydrolysis kinetics twist
The method of the blue saponin(e of stock, it is characterised in that：Comprise the following steps：
（1）Gynostemma pentaphyllum herb is taken, coarse powder is ground into or is cut into segment, plus higher concentration alcohol, refluxing extraction 1-3 times, each 0.5-3
Hour, filtration, filtrate reclaims alcohol, is dissolved in water, and filters, obtains filtrate；
（2）By on filtrate on large pore resin absorption column, make the active ingredient in gynostemma pentaphylla be slowly adsorbed in post bed in resin
On, with water elution, then with the elution removal of impurities of low concentration alkali lye, it is washed with water to neutrality, eluent is discarded；
（3）Again with the elution of low concentration alcohol with suitable flow velocity removal of impurities, low-concentration ethanol washing lotion is discarded；
（4）Gypenosides are eluted with suitable flow velocity with higher concentration alcohol again, higher concentration alcohol eluen is collected, merged,
Reclaim, then be dried under reduced pressure, as gypenosides.
The total saponin content in gynostemma pentaphyllum total soap made from determined by ultraviolet spectrophotometry is used in the present invention, with gynostemma pentaphylla
Saponin A meter, content is 92% ~ 94%.
Further, the higher concentration alcohol of the step (1) is 40%-95% methanol or ethanol, and amount used is medicinal material amount
6-30 times；
Further, the low concentration alkali lye described in the step (2) is 0.5%-10% sodium hydroxide or potassium hydroxide or ammonia
Test solution, eluting agent is 1-7 times of resin volume；
Further, in the step (1), described gynostemma pentaphyllum herb is to be cut into the gynostemma pentaphylla of short section or be ground into coarse powder
Gynostemma pentaphylla；
Further, in the step (2), the active ingredient in described gynostemma pentaphylla is gypenoside；
Further, in the step (2), macroreticular resin used is low pole and nonpolar macroporous adsorption resin, including but
It is not limited to AB-8, D101, HPD100, NKA-2 etc.；
Further, the low concentration alcohol of the step (3) is 20%-40% methanol or ethanol, and flow velocity is 0.5-2 times of column volume
Per hour, eluting agent is 2-6 times of resin volume；
Further, the higher concentration alcohol of the step (4) is 50%-95% methanol or ethanol, and flow velocity is 0.5-2 times of column volume
Per hour, eluting agent is 2-8 times of resin volume.
Compared with prior art, it is an advantage of the current invention that
Only extracting n-butyl alcohol is not used, that is, reaches purification effect using a purifying resin in this method, its saponin(e amount lost
Few, cost is low, and the cycle is short.The method of extraction purification gypenosides from gynostemma pentaphylla of the present invention, available for industrial metaplasia
Production, cost is low, and technological process is short.
