Background technology:
Motherwort Herb is called the female wormwood artemisia of Motherwort Herb benefit, benefit female Chinese mugwort, safflower Chinese mugwort, female grass, motherwort, triangle linseed, four a stupefied son wild flax, Tian Ma Kuo, nine towers are colored, the mountain is numb and veronica.These product are the fresh or dry aerial parts of labiate Motherwort Herb Leonurus japonicus Houtt..Summer, extract herb on the ground when the autumn blooms, remove impurity, cut-out is dried.Herb contains syringic acid.delta.-guanidinobutyl ester (leonurine) 0.05%, and this composition that comes into bloom only contains trace, and increases gradually in flowering period.Other contains stachydrine (stachydrine), syringic acid.delta.-guanidinobutyl ester first and second, the syringic acid.delta.-guanidinobutyl ester first is the nitrite (leonurinenitrite) of syringic acid.delta.-guanidinobutyl ester. in addition, contain phytomelin and fumaric acid. and laudanum alkane (labdan) type diterpene compound Motherwort Herb element (leosibirin), different Motherwort Herb element (isoleosibirin) and Motherwort Herb qin element (leosibiricin). flower contains Motherwort Herb booth alkali (leonuridine).
Stachydrine Stachydrine belongs to alkaloids, and this product has promoting blood flow to regulate menstruation, inducing diuresis to remove edema, the effect in contraction uterus.To myocardial ischemia that suprarenin causes be improved coronary artery and Nutritional myocardium blood flow amount, reduce the myocardium cell necrosis amount, reduce blood viscosity, reduce vascular resistance, improve microcirculation, the effects such as reducing heart rate, minimizing cardiac output and anti-platelet aggregation.Existing Motherwort Herb technique adopts conventional the extraction more, and Zeo-karb is processed, ammoniacal liquor wash-out, or agent treated again.Publication number be CN101863814A with the profit application, it discloses the method for refining stachydrine in a kind of Motherwort Herb, product content is up to 95%, but this extraction and separation process, extraction efficiency is lower, complex steps in the later stage exquisiteness, practical application effect are nothing like the effect of utilizing countercurrent extraction, macroporous adsorbent resin coupling silica gel column chromatography to separate.
Summary of the invention
The object of the invention is to provide a kind of production technique of Motherwort Herb stachydrine; The object of the invention also be to provide a kind of convenient and swift, raw material sources abundant, extraction efficiency is high, separation and purification successful, the production technique of utilizing Continuous Countercurrent Extraction and enriching and purifying macroporous resin Motherwort Herb stachydrine that dna purity is high.
The present invention seeks to be achieved through the following technical solutions.
A kind of production technique of Motherwort Herb stachydrine, its step is as follows:
(1) Motherwort Herb is pulverized the rear continuous countercurrent extracting tank aqueous ethanolic solution refluxing extraction that adds;
(2) extracting liquid filtering that will process through (1) gets Motherwort Herb stachydrine crude extract:
(3) gained Motherwort Herb stachydrine crude extract is concentrated, get the thick concentrated solution of Motherwort Herb stachydrine;
(4) with the thick concentrated solution thin up of gained Motherwort Herb stachydrine, and filter, get filtrate;
(5) with the upper broad spectrum type macroporous resin adsorption post of gained filtrate, adsorb the complete impurity that washes with water, use again the ethanol aqueous wash impurity of low powered posterior chamber, then use the aqueous ethanolic solution wash-out of the high number of degrees, get Motherwort Herb stachydrine elutriant;
(6) the gained elutriant is condensed into cream, gets Motherwort Herb stachydrine condensed cream;
(7) Motherwort Herb stachydrine condensed cream is mixed silica gel, and the mixture that will mix through ethyl acetate and sherwood oil mixed solution wash-out, gets elutriant as for the silicagel column top;
(8) elutriant is reclaimed solvent after concentrate drying get Motherwort Herb stachydrine work in-process;
(9) Motherwort Herb stachydrine work in-process are dissolved with aqueous ethanolic solution, filter, Recycled ethanol, concentrated, place crystallize out, suction filtration gets Motherwort Herb stachydrine finished product.
In the described step (1), cross 30~80 mesh sieves after Motherwort Herb is pulverized and carry out the aqueous ethanolic solution refluxing extraction again, the extraction solvent is 50%~85% aqueous ethanolic solution.
In the described step (1), the equipment that extracts is the countercurrent extraction production line, comprises lift, charging transmission, countercurrent extraction tank group main frame 1, draws glassware 1, Juice squeezer 1, countercurrent extraction tank group main frame 2, draws glassware 2, Juice squeezer 2, discharging transmission, line pump, Pump for giving-out, temporary tank, interchanger, liquid flowing valve etc.Raw material is at the uniform velocity added by lift charging opening place behind the crushing screening, and extracting solution pumps via Pump for giving-out continuously from flowing to temporary storage tank.
In the described step (1), adverse current production line parameter is lift frequency 15~30Hz, main frame 1 frequency 18~20Hz, Juice squeezer 1 frequency 45~50Hz, main frame 2 frequencies 20~22Hz, Juice squeezer 2 frequencies 40~45Hz, Pump for giving-out flow 0.5~2T/h, charging 100~400kg/h.
In the described step (4), the dilution water yield is 5 times of concentrated solution volume, filters to such an extent that impurity discards.
In the described step (5), the macroporous resin adsorption step adopts wet method dress post, keeps liquid level, and filtrate is passed through adsorption column, flow velocity per minute 0.05ml/g resin, and the resin model is HPD400, HPD100, DM-130 or AB-8 broad spectrum type macroporous adsorbent resin.
In the described step (5), the macroporous adsorptive resins aspect ratio is 10~5: 1, the aqueous ethanolic solution of low powered posterior chamber is 5%~20% aqueous ethanolic solution, the aqueous ethanolic solution of the high number of degrees is 50%~80% aqueous ethanolic solution, washing the impurity water yield is 3~5BV, the aqueous ethanolic solution amount of washing the impurity low powered posterior chamber is 1~2BV, and the aqueous ethanolic solution amount of the high number of degrees of wash-out is 4BV.
In the described step (7), the silica gel column chromatography step adopts wet method dress post, keep liquid level, condensed cream is mixed the rear silica gel of activation by weight at 1: 1, and the mixture that will mix places the silicagel column top, elutriant is ethyl acetate: the sherwood oil volume ratio is 50~85: 15 ethyl acetate and sherwood oil mixture, elution flow rate per minute 0.1ml/g silica gel, and elution volume is 5BV.The silica gel activating condition is 110 ℃ of 30min.
In the described step (9), Motherwort Herb stachydrine work in-process are measured 60 ℃ of thermosols of 50% aqueous ethanolic solution with 12~16 times.Concentrated density is d=1.03~1.05.
The present invention discloses a kind of production technique of Motherwort Herb stachydrine, the method is: will drop into from cast hopper after the raw material pulverizing, the rotation of extractor group main frame, material is slowly advanced backward from the unit front end, the liquid-inlet pipe that extracts simultaneously solvent slave group end enters in the extractor, pass mobile material forward end by the tank rear end and flow, solid-liquid two-phase material is fully contact in this inverse motion, thereby with extracts active ingredients in the medicinal material out.The dregs of a decoction are forced to be pushed to slag notch and are discharged through the discharging forwarder, and special Juice squeezer pushes the dregs of a decoction, and dregs of a decoction Shen residual liquor is extruded the medicinal material tissue, reduces dregs of a decoction Shen residual liquor content.Extraction efficiency is higher, extraction is more complete.
The present invention selects macroporous adsorbent resin and binding silica gel column chromatography purification simultaneously, and separating effect is better.
