Description
Technical field
The present invention relates to a kind of preparation method of herbal medicine paper mulberry fruit seed oil, this fatty oil is mainly used in industries such as medicine, food, makeup.
Background technology
Chu Shizi is the dry mature fruit of moraceae plants paper mulberry [Broussonetia papyrifera (L.) Vent.], is distributed in China North China, northwest, East China, Central-South, southwest and Liaoning.Have the kidney tonifying clearing liver, make eye bright, the effect of diuresis is used for the treatment of soreness of the waist and knees clinically, the consumptive disease hectic fever due to yin, and dizzy blurred vision, order is given birth to film, and the oedema turgor can also be treated tetter such as stubborn dermatitis, neurodermatitis, eczema." Mingyi Bielu " carries to top grade: sweet, cold, nontoxic.The real son of the many records of ancient book on Chinese herbal medicine Chu is a tonic, carries to top grade as " Mingyi Bielu ": sweet, cold, nontoxic.The big help of function, clothes are not hungry, not old for a long time, make light of one's life by commiting suicide.Modern document shows that also it has anti-senile dementia or delays senile dementia, improves the effect of cognitive function, and is effective to chronic hepatitis C by the Chinese medicine preparation liver relieving capsule that Chu Shizi etc. forms in addition, and alanine aminotransferase is had clear improvement.The treatment Jaundice Jaundice there is special efficacy.Chu's reality, Root of coastal Glehnia, give birth to compatibility such as cultivated land and use and to improve the hepatic and renal YIN deficiency and be used for the treatment of type hepatitis special efficacy is arranged.Compatibility uses such as Chu's reality, Root of coastal Glehnia, living cultivated land can improve the hepatic and renal YIN deficiency and be used for the treatment of posthepatitic cirrhosis, and total effective rate 88%, HBsAg negative conversion rate are 67.7%.Can improve liver function to yellow subcutaneous ulcer companion hepatomegaly patients with ascites, recover serum bilirubin." setting upright disappears makes soup " formed with the real compatibility of Chu is to tangible hepatic ascites 65 examples of the deficiency of Yin, total effective rate 90.7%.The real son of Chu can be treated ephrosis, real with Chu, obtain treatment chronic nephritis such as tongue and deficiency of kidney-QI type patient effective.With depleted double oedema person of treatment chronic renal merits such as the luxuriant 5 usefulness Chu Shizi of Huang and urinary system calculus certain effect is arranged all also.Papermulberry Fruit also can be used to treat ophthalmic diseases and gynaecology's infertility, with the real son of Chu is the medicine that main ingredient is made, energy therapeutic community's property retinitis, can promote infertility women ovulation, male sterility is comprised all kinds of patients of impotence, premature ejaculation, involuntary emission, anejaculation and cacospermia also produce effect more.In addition, to treating bald class, senile morning, Baldo had curative effect preferably.Prospect application prospect, Papermulberry Fruit not only have the potentiality of exploitation treatment geriatric disease new drug, can also make the product of beauty and health care class.
Paper mulberry fruit seed oil tradition is extracted and partition method: promptly with organic solvent extraction such as sherwood oils through crushing screening Papermulberry Fruit fruit, with sherwood oil cold-maceration or seepage method,, concentrate and reclaim solvent and promptly get brown paper mulberry fruit seed oil cold soaking or the solution suction filtration that leaks out.Comprise pigment owing to contain the impurity of other property in the grease, also need to make with extra care.Extract must be added on the silicagel column, the solvent of using opposed polarity respectively is as flushing such as sherwood oil, ether, acetone pillar.Reclaim solvent and obtain elaboration.More than these methods exist that complex process, cycle are long, extraction yield is lower, poor selectivity, effective constituent destructible, production efficiency be low.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of paper mulberry fruit seed oil, with good, the inclusion-free of oil quality that this method is extracted, technology is simple, and cost is low.
In order to achieve the above object, the technical measures of the present invention's employing are: utilize supercritical CO
2(SFE-CO
2) fluid extraction technology is as extracting method, this method is exactly to utilize the gas under the super critical condition to make extraction agent, extracts some composition from liquid or solid.In the operation, be that Papermulberry Fruit really is crushed to 10-20 purpose granularity, in extraction cell, feed CO
2, making it reach the supercritical state point and extract, the logistics of extraction back is discharged from the extraction cell top exit and is entered the separate chamber, through separating of step-down or heat up back realization solute and solvent.
The paper mulberry fruit seed oil that extracts by above technology separates by molecular distillation equipment again, obtains highly purified unsaturated fatty acids.
A kind of preparation method of paper mulberry fruit seed oil, its step is as follows:
1, Papermulberry Fruit feedstock production: the Papermulberry Fruit fruit is pulverized after drying, and temperature is 58-62 ℃, and drying time is 5-7 hour, crosses the 10-20 mesh sieve, gets Papermulberry Fruit.
2, system is prepared and charging: extraction cell, Resolution Room A, Resolution Room B and ice chest are heated respectively or cool off, and the temperature of adjusting extraction cell is 50-60 ℃; Resolution Room A temperature is 35-50 ℃; Resolution Room B temperature is 30～50 ℃; The temperature of ice chest is 4-5 ℃, drops into Papermulberry Fruit in the supercritical extraction chamber.
3, supercritical extraction preparation: open CO
2Gas bottle is pressurizeed to preceding 3 kinds of equipment by compression pump, and the pressure of regulating extraction cell is 28-35MP; The pressure of Resolution Room A is 5-12MP; The pressure of Resolution Room B is 5-8MP, cycling extraction, and transfer CO
2Flow be 26-27.5L/ hour, keep constant temperature and pressure after 1.5-2 hour, from the Resolution Room discharge hole for discharge, light yellow transparent oily liquid, promptly get the paper mulberry fruit seed oil, containing linolic acid in the gas chromatography determination paper mulberry fruit seed oil is 61-64%.
The present invention compared with prior art has the following advantages and effect:
1. overcritical SFE-CO
2Substitute traditional conventional extracting method such as organic solvent extraction method, technology is simple, the cycle is short, extraction yield is high, selectivity is good, production efficiency is high and do not destroy linolic acid.
2. characteristics such as separation degree and product yield height, nontoxic, harmless, pollution-free, noresidue, can obtain pure safe natural product, be applicable to comparatively complicated mixture, the purification that separates to the high viscous material of thermo-responsive and added value can be used multiple-grade molecular distillation and supercritical liquid extraction technique.
