Abstract
The invention discloses a Poanthocyan extraction process from rapeseed husk comprising one extraction step and two steps of purification, i.e. centrifugal sedimentation and propanone deposition, wherein in the extraction step ethanol containing 40%-80% (v/v) of moisture is used as the extraction solvent, the weight ratio of Chinese colza peel amount and dissolvent amount is 1:5-12, the two purification steps comprises centrifugal sedimentation 3-10 min of the compression liquid in centrifugal machine after reclaiming ethanol, filtering and rouging, charging propanone into the compression liquid, agitating 2-10 min, stewing 5-20 min, filtering and rouging, recovering propanone, drying under the temperature of 40-80 deg. C to obtain the end product.
Description
Technical field: the invention belongs to chemical technology field, be applicable to the processing of Semen Brassicae campestris skin dregs of rice deep development, be specifically related to from the Semen Brassicae campestris skin, extract the technology of proanthocyanidin.
The prior art situation: Semen Brassicae campestris is large oil crops, adopt the decortication production technique can make the pure natural rapeseed oil, the vegetable seed skin of deviating from accounts for about 12% of Semen Brassicae campestris amount, except that being used for leaching the system oil, be used for fungi culture medium more or make boiler oil, use value and economic worth are lower.Contain natural active matter in the Semen Brassicae campestris skin---proanthocyanidin.Proanthocyanidin has very strong anti-oxidant activity, at medicine, and healthcare products, food, there is purposes widely the daily-use chemical industry aspect, has high value.Now, proanthocyanidin extracts in the Cortex Pini mainly from Semen Vitis viniferae, extracts proanthocyanidin and do not appear in the newspapers from the Semen Brassicae campestris skin.
Goal of the invention: purpose of the present invention just is to make full use of Semen Brassicae campestris skin resource, and it is simple to propose a kind of technology, has the industrialized technology of extracting proanthocyanidin from the Semen Brassicae campestris skin.Its anti-oxidant activity of Semen Brassicae campestris skin proanthocyanidin that extracts is more than 5 times of Cortex Pini proanthocyanidin.
The invention scheme: purpose of the present invention can be passed through following technique measures, be that twice purifying process of single extraction realized: with the Semen Brassicae campestris skin dregs of rice behind water content 8%～16% (w/w) Semen Brassicae campestris skin or the leaching system oil, add moisture 40～80% (v/v) alcohol solvent in 1: 5～12 (w/w) ratio, behind 50～80 ℃ of temperature condition extraction 3～6h, remove by filter Semen Brassicae campestris skin slag, get extraction liquid, with extraction liquid heating recovery ethanol, make concentrated solution, then with concentrated solution centrifugal settling in 3000～5000r/min separating centrifuge, remove by filter impurity then, add acetone again in concentrated solution, the ratio of concentrated solution and acetone is 1: 1～5 (v/v), and impurity further is precipitated out, filter decon, the filtrate that obtains enters the moisture eliminator cryodrying after reclaiming acetone, or spraying drying, drying temperature is 40～80 ℃, is dried to be solid state and to be finished product.
Invention advantage: the advantage that the present invention had:
1. provide method for from oil plant processing byproduct Semen Brassicae campestris skin, producing natural active matter.
2. the Semen Brassicae campestris skin proanthocyanidin anti-oxidant activity that makes is high, is more than 5 times of Cortex Pini proanthocyanidin.
3. technology is simple, and energy consumption is lower, and is scientific and reasonable.
4. the Semen Brassicae campestris skin that extracts proanthocyanidin still can be done him in addition and use after reclaiming solvent.
Embodiment further describes the present invention below in conjunction with accompanying drawing.
Accompanying drawing is embodiments of the invention.
Embodiment:
The Semen Brassicae campestris skin that will contain moisture 10% referring to accompanying drawing, add solvent after entering container, solvent is the ethanol (v/v) that contains moisture 60%, Semen Brassicae campestris skin amount is 1: 10 (w/w) with the ratio of solvent adding amount, extract 3.5h down for 70 ℃ in temperature, the extraction after-filtration is removed Semen Brassicae campestris skin slag, and extraction liquid and Semen Brassicae campestris skin slag are reclaimed ethanol respectively, and the skin slag is done him in addition and used.Extraction liquid obtains concentrated solution after reclaiming ethanol, centrifugal settling 10min in the whizzer of 3000/min, remove by filter impurity, add acetone in the concentrated solution then, concentrated solution is 1: 3 with the ratio of acetone, make the proanthocyanidin dissolving, 30 ℃ of solvent temperatures cause water-soluble impurity to be precipitated out, and stir 10min, leave standstill 20min, filter decon, filtrate enters the cryodrying chamber or carries out spraying drying after reclaiming acetone, and 40～80 ℃ of drying temperatures are finished product until being the tawny solid state, product proanthocyanidin content is more than 83% after testing, and the product yield is about 2.4%.The resistance of oxidation of Semen Brassicae campestris skin proanthocyanidin is more than 5 times of Cortex Pini proanthocyanidin.
Claims (2)
1, a kind of technology of producing proanthocyanidin from the Semen Brassicae campestris skin is characterized in that comprising single extraction, twice purifying technological processs such as (centrifugal settling, acetone precipitations).Single extraction is to contain the Semen Brassicae campestris skin of moisture 8%～16% (w/w) with containing the ethanol (v/v) of moisture 40%～80% as extraction solvent, Semen Brassicae campestris skin amount is 1: 5～12 (w/w) with the ratio of solvent load, in extraction temperature is that 50 ℃～80 ℃ condition extracts, the extraction time is 3～6h, twice purifying is: the concentrated solution centrifugal settling 3～10min in the whizzer of 3000～5000/mn behind the recovery ethanol, filter impurity elimination, in concentrated solution, add acetone then, concentrated solution is 1: 1～5 (v/v) with the ratio of acetone, stir 2～10min, leave standstill 5～20min, remove by filter impurity, concentrated solution gets product 40 ℃～80 ℃ cryodryings after reclaiming acetone.
2, produce the technology of proanthocyanidin in the Semen Brassicae campestris skin according to claim 1, it is characterized in that: described raw material is the Semen Brassicae campestris skin or the Semen Brassicae campestris skin dregs of rice after leaching system oil.
