Abstract
The invention discloses a process of extracting silymarine by using alcohol as a single organic solvent, adopting edible alcohol to extract silymarine, then adopting alcohol and water to wash twice so as to eliminate oil and impurities, using edible sodium carbonate for elution, drying the silymarine solids obtained by fulling and then crushing and obtaining the final product, where by the UV determination, the total flavone content in the silymarine has mass percent concentration of 70%-90%, the product yield is 2-3% of the quantity of silymarine seeds from which the oil has been extracted. It solves the problem of harmful solvent residues in current silymarine products, and it can obtain the silymarine products without harmful solvent residues.
Description
Technical field
The present invention relates to traditional Chinese medical science pharmacy field, relate in particular to from natural product herbal medicine separation and Extraction monomer medicine with the silymarin extraction process of ethanol as single organic solvent.
Background technology
Silymarin is the general name of the Flavonoid substances that extraction separation goes out from the seed of natural product Silymarin, has mainly comprised 5 kinds of Flavonoid substances such as silibinin, Isosilybin.That silymarin has is anti-oxidant significantly, remove effect such as free radical, is mainly used at present in the treatment of hepatopathy, and secondly, silymarin also has significant curative effect for the some diseases of cardiovascular systems such as hyperlipidemia etc.
The early stage ethyl acetate that adopts that is extracted in of silymarin is carried out more, silymarin adopts acetone to extract from the Silymarin seed mostly at present, carry out degreasing with sherwood oil or hexane etc. then, obtain yellow or yellowish powder-product, the comparative study report that adopts methyl alcohol to extract is also arranged.Do not see at present that both at home and abroad correlative study or patent report are arranged and there is the residual Silymarin extraction process of hazardous solvent.
In recent years, because the human consumer of the U.S., Europe, Japan is more and more stricter for the requirement of solvent residual amount, not only there is dissolvent residual in the plant milk extract that adopts present methyl alcohol, acetone, sherwood oil, ethyl acetate, hexane etc. can cause the organic solvent separation and Extraction of certain murder by poisoning to obtain to human body, but also the problem that often exists residual solvent to exceed standard.
Summary of the invention
The objective of the invention is to overcome the shortcoming of the above hazardous solvent residue that in the silymarin leaching process, exists, propose a kind of with the silymarin extraction process of ethanol as single organic solvent.Extraction process of the present invention only adopts ethanol as single organic solvent, adopts gradient method technology, has solved the dissolvent residual problem in the silymarin.
Technical scheme of the present invention adopts extraction using alcohol to fly the processing method of silibin, may further comprise the steps:
1) with the oil expression of Silymarin seed process, oil yield is about 15% of the preceding seed weight of oil expression, presses into the oil cake that thickness is 1-3mm;
2) the Silymarin oil cake powder that will press oil is broken into the extractor of packing into after 20 orders sieve, and the edible ethanol that adds concentration and be 85%-95% is heated to the boiling back and keeps constant temperature backflow 1.5-3 hour to flooding height of materials, extracts 3-5 time continuously;
3) concentration tank of will the Silymarin extracting solution behind extraction using alcohol packing into concentrates, when ethanol content in the concentrated solution through the alcoholic degree instrumentation fixed less than 10% after, emit concentrated solution, concentrated solution is cooled to below 40 degrees centigrade, emit the upper liquid vegetables oil, the solids of bottom with the hot water injection more than 60 degrees centigrade, is removed the part grease of solid surface;
4) in the gained solids, add the softening water of 5 times of weight, more than the heated and stirred to 70 degree centigrade, kept 30 minutes to 2 hours, emit supernatant liquid then, stay solids;
5) ethanol of 3-5 times of weight concentration 10%-50% of adding in above gained solids keeping 30 minutes to 2 hours more than 70 degrees centigrade, is emitted supernatant liquid then, stays solids;
6) in above gained solids, add the softening water of 2-5 times of weight, more than the heated and stirred to 70 degree centigrade, kept 30 minutes to 2 hours, pour out supernatant liquid then, stay solids;
7) ethanol of 3-5 times of weight concentration 10%-50% of adding in above gained solids kept 30 minutes to 2 hours at constant temperature more than 70 degrees centigrade, poured out supernatant liquid then, stayed solids;
8) in above gained solids, add 2-5 times of weight softening water, more than the heated and stirred to 70 degree centigrade, kept 30 minutes to 2 hours, pour out supernatant liquid then, stay solids;
9) in above gained solids, add mass percent concentration be 0.1%-2% edible sodium carbonate solution 1-5 doubly, keeping 10 minutes to 2 hours more than 60 degrees centigrade, pour out supernatant liquid then, again with 3-10 doubly measure, hot water more than 70 degrees centigrade carries out rinsing and removes edible yellow soda ash, after the solids drying of gained, pulverize and promptly obtain no solvent residue silymarin the finished product.
The silibin process for extracting that flies of the present invention can obtain not having the residual silymarin product of hazardous solvent, Herba Silybi mariani total flavones content is mass percent 70%-90% through the result of ultraviolet determination in the product, product yield was for pressing the 2%-3% of oil back Silymarin seed, and ethanol content is less than 0.5% in the product.
