Abstract
The present invention relates to the extraction of proanthocyanidin from plants, particularly to a resin method of extracting proanthocyanidin from grape seeds. The grape seeds are used as raw materials; water and/or alcohol is adopted as solvent; the proanthocyanidin is extracted under the conditions of normal temperature or heating; after extracting liquid is filtered, solvent alcohol is recovered and is then concentrated; water is added for filtering; after the processed macroporous absorption resin on the filter liquid is saturated by absorption, the macroporous absorption resin is eluted by an alcohol water solution, and after eluent is recycled and the solvent is dried, the product is obtained. The product yield is from 3% to 10% and the content of the proanthocyanidin is from 38% to 90%. The present invention has the advantages of high product purity, low cost, easy acquirement of raw materials, friendly environment and no solvent residue problem, and the content of the proanthocyanidin used as a product is 90%. Accordingly, the proanthocyanidin is suitable for industrialized production.
Description
Technical field
The present invention relates to the extraction of pycnogenols in the plant, specifically a kind of resin method extracts the method for pycnogenols in the Semen Vitis viniferae.
Background technology
Procyanidin compounds (proanthocyanidins) is the polymer of flavonoid compounds such as flavane-3,4 glycol and Flavonol, and most of plants all contain pycnogenols.But it is more with content in the plants such as Cortex Pini, Semen Vitis viniferae, lemon bark; This compounds, particularly oligomerization pycnogenols (opc) can significantly improve the anti-ageing ability of body by removing unnecessary free radical in the body, improve heart function, strengthen the ability of human body resistance reaction; Pharmacological evaluation shows: it has the strongly inhibited effect to diseases such as arteriosclerosis, stomach ulcer, intestinal cancer, cataract, diabetic complicationses; The resistance of oxidation of pycnogenols is ascorbic 200 times, and 50 times of vitamin-E are to remove the strongest natural antioxidants of free radical ability at present.The production technique of this compounds or the research of preparation process, application approach, structure and character all had crucial meaning.
At present, various functional food and medicine have been developed abroad, as: France professor Jacques Masquelier in nineteen fifty-one find first OPC anti-oxidant activity and in 1969 at U. S. application patent (US3436407), raw material is the Korean pine bark, boiling water extraction, the ethyl acetate extraction crude extract, the trichloromethane precipitated product.The He Minming that has of Japan is a raw material with the bark, uses water extraction, and petroleum ether gets product.U.S. ARIGA from Cortex Pini with methanol extraction, petroleum ether, ethyl acetate extraction, liquid-phase chromatographic column separate product, and applied for a patent [US 4797421 (1989)] in 1989.Poland OSZMIANSKIJAN applied for a patent [POL 69082 (1996)] in 1996, be solvent with acetone, adopted ultrasonic wave to extract OPC from Semen Vitis viniferae, extracted the trichloromethane precipitated products with ethyl acetate at-18 ℃.U.S. HENKEL company applied for a patent in 1997, from Semen Vitis viniferae, and with boiling water extraction, ethyl acetate extraction crude extract, trichloromethane precipitation product.Foreign patent mostly exists raw material to be not easy to obtain, adopt poisonous (chloroform), inflammable (ethyl acetate, oil fan), volatile organic solvent in the production, or under cold condition, produce, final product derives from the chloroform soln, the dissolvent residual height, be difficult to reach standard, corresponding production cost improves.Or adopt liquid item chromatographic column (Poland), be difficult to be fit to large-scale industrial production.Domestic development and use to pycnogenols are just at the early-stage.Synthetic free-radical scavengers discovered in recent years toxic side effect, seeking oxygenant from natural product becomes a kind of trend.
Summary of the invention
The object of the present invention is to provide low, the eco-friendly resin method of a kind of cost to extract the method for pycnogenols in the Semen Vitis viniferae.
For achieving the above object, the technical solution used in the present invention is: be raw material with the Semen Vitis viniferae, adopting water and/or alcohol is solvent (promptly Chun concentration can be 0～100%), under normal temperature or heating condition, extract (promptly extract temperature and can be room temperature～boiling), behind the extracting liquid filtering, the recovery solvent alcohol concentrates, add water filtration, the macroporous adsorbent resin of handling on the filtrate, adsorb saturated after, use the alcohol solution wash-out, elutriant reclaim after the solvent seasoning product, the yield of product is 3%-10%, and procyanidin content is 38%-90%;
The normal model that adopts of wherein said macroporous adsorbent resin is D101 or D201; Described alcohol is normal adopt methyl alcohol, ethanol, propyl alcohol and butanols arranged, preferably select ethanol for use; The Semen Vitis viniferae raw material can be pulverized afterwards earlier before processing and extract, and also can directly extract; Extraction time is generally and got final product in 0.5～5 hour; The determining alcohol of macroporous adsorbent resin elutriant can be 20～100%; The determining alcohol of removal of impurity elutriant can be 0～10%; What drying means often adopted can be vacuum-drying, evaporate to dryness or spraying drying etc.; In the leaching process between Semen Vitis viniferae and solvent consumption be preferably 1 (g) Semen Vitis viniferae: 3～5 (ml) solvent;
The treatment process of wherein said macroporous adsorbent resin is: at first adopt acetone wash-out resin colourless to elutriant, water elution is not to there being acetone, and 85% ethanol elution is colourless to elutriant, washes with water to there not being the alcohol flavor, and is standby.
The present invention has following advantage;
1. product purity height.The present invention is that raw material employing water or alcohol are solvent first with the Semen Vitis viniferae, extracts pycnogenols by the method for crossing macroporous resin, and can make the product procyanidin content reach 90%
2. cost is low.Raw material is easy to get, and enforcement of the present invention is compared with reaching domestic production method at present abroad, and product per ton can be saved production cost more than 50%, and its benefit is considerable.
3. environmental friendliness.It is solvent that the present invention only adopts the alcohol of food grade, does not have the dissolvent residual problem, and production process does not adopt deleterious organic solvent, has reduced the danger and the toxic of producing simultaneously.
4. suitability for industrialized production.Good product quality, no solvent residue, product conformance with standard.
