Description
Technical field
The present invention relates to a kind of method for preparing plants essential oil, specifically is with supercritical CO
2Technology extraction binding molecule distills and prepares plants essential oil.
Background technology
Plants essential oil is the plant specific aromatoising substance, is taken from herbal flower, leaf, root, bark, fruit, seed, resin etc. and extract with distillation, squeezing mode.Plants essential oil is to be made up of the one-tenth branch more than the kind more than 100, and some more constitutes up to hundreds of extremely thousands of kinds of compositions certainly, and generally speaking plants essential oil contains alcohols, aldehydes, acids, phenols, acetone class, terpenes.With the Flos Rosae Rugosae quintessence oil is that example 86% is to be become to be grouped into by kind more than 300, the 14%th, to form by many minor compounds, and this two-part composition ratio is different, also can influence taste and curative effect.Contain Mang geraniol and the vernol of geraniol, the 3-40% of 33-55%, the stearopten of 16-22%, the phenylethyl alcohol of 1.5-2%, the sesquiterpene cycloalcohol of 0.2-2% in the Bulgarian Rose, and some micro-syntheticss.
At present, supercritical CO is mainly adopted in the preparation of plants essential oil
2The lixiviate of technology extraction or chemical solvents.Supercritical fluid extraction (Supercritical Fluid Extraction; SFE) be to utilize the special property that fluid had and the emerging abstraction technique that forms near stagnation point; Its principle is to utilize the dissolving power of supercutical fluid and the relation of its density, promptly utilizes pressure and temperature that the influence of supercutical fluid dissolving power is carried out.Supercritical CO
2Be a kind of fluid that the most often uses, it is neither liquid, neither gas; But possesses the high-density of liquid and the low viscous character of gas; Therefore higher dissolving power and higher diffusion are arranged, can mix fully, contact, bring into play its dissolving power to greatest extent with sample.
Traditional plant essential oil purification process adopts the problem that methods such as low temperature crystallization, fractionation by adsorption, urea clathration all exist needs to use a large amount of organic solvents more, and residual organic solvent can produce detrimentally affect to human body.Remove organic solvent and mainly adopt methods such as rotary distillation, washing, and these all will cause production cost to increase or remove not thorough.Adopt chemical solvents lixiviate plants essential oil, add ethanol again after for example adopting the sherwood oil lixiviate, cold filtration is removed insoluble wax, and cold filtration is removed secondary wax again, and the ethanolic soln concentrating under reduced pressure gets essential oil.Not only use a large amount of organic solvents, and the essential oil fragrance that obtains is relatively poor, color is darker, and yield is lower.
Short-path distillation is a kind of distillating method of under high vacuum, operating, and at this moment the mfp of vapour molecule is greater than the distance between water surface of evaporation and the condensing surface, thereby the difference of each component vaporator rate in the feed liquid capable of using is separated liquid mixture.
Complicated in view of plant-derived essential oil, pufas is prone to oxidation in leaching process, and how the process for extracting of plants essential oil adopts supercritical COs separately at present
2Extraction, the essential oil content that obtains is low, and yield is low, is the method for the Chinese invention patent hypercritical CO 2 extracting Jasmine oil of CN1173531 like publication number, and the time is long, and the essential oil content that obtains is low.For example publication number is a kind of supercritical CO of Chinese invention patent of CN1380380 again
2The method of natural essence oil also is that yield is low in the fluid extraction purification sophora flower, and the essential oil content that obtains is low.Most methods can only be directed against single plant extract plants essential oil at present, extract and develop a kind of various plants essential oil that can both be applicable to fast, and the method that the yield of essential oil is high, content is high is extremely necessary.
Summary of the invention
The purpose of this invention is to provide a kind of fast, the method for extraction plants essential oil that efficient is high.
The present invention provides a kind of method for preparing plants essential oil, and concrete steps comprise:
1) gets raw material, pulverize, place extraction kettle, with supercritical CO
2Fluid is an extraction solvent, and the ethanol that with the volumetric concentration is 55-65% is that entrainment agent carries out supercritical extraction, separates obtaining medicinal extract through separating still; Wherein extraction temperature is 25-38 ℃; Extracting pressure is 15-22Mpa; The extraction time is 1.5-3 hour, and the quality of said raw material (Kg) is 0.2-0.5 with volume (L) ratio of extraction kettle: 1, and the consumption of said entrainment agent (L) is 0.05-0.07 with volume (L) ratio of extraction kettle: 1;
2) medicinal extract of getting step 1) extraction gained places molecular still, under 0.3-0.5Pa, 160-180 ℃ condition, carries out short-path distillation, collects and obtains corresponding plants essential oil.
Raw material described in the step 1) of the present invention is: sweet osmanthus, Flower of Arabian Jasmine, Lysimachia foenum-graecum, the bark of official magnolia, Grosvenor Momordica or passion fruit.
Raw material described in the step 1) of the present invention is drying, described drying specifically can be to dry or other existing method is carried out; The granularity of pulverizing is the 20-60 order.
In the step 1) of the present invention, described extraction temperature is 35 ℃, and extracting pressure is 18Mpa, and the extraction time is 2 hours.
In the step 1) of the present invention, the volume (L) of quality of described raw material (Kg) and extraction kettle is than being preferably 0.3: 1; The volume (L) of consumption of said entrainment agent (L) and extraction kettle is than being preferably 0.05: 1.
Pressure during short-path distillation step 2 of the present invention) is preferably 0.4Pa, temperature is preferably 170 ℃.
Compared with prior art, the present invention has following advantage:
1, the present invention can extract essential oil to various plants;
2, the present invention begins from purification process, reduces or avoid the use of organic solvent;
3, adopt supercritical extraction and short-path distillation to have easy to operate; Have pollution-free, characteristics such as service temperature is low, selectivity good, one step of separation accomplishes, extraction noresidue; Wherein molecular distillation technique still is a kind of efficient, safe liquid-liquid stripping technique, and the combination of these two kinds of technology is fit to suitability for industrialized production; Cost is low, safety;
4, at present a lot of supercritical COs
2The temperature that the fluid extraction plants essential oil adopts is hided at 45-70 ℃, and temperature is high, causes oxidation of fatty acids in the essential oil easily, reduces the quality of essential oil, and the present invention adopts lower temperature operation, can effectively prevent fragrance component oxidation and degraded, keeps the aroma component of plant;
5, adopt method of the present invention, the yield of essential oil is high, and content is high: the essential oil yield of prior art is below 3.5%, and yield of the present invention is more than 7%, and the essential oil content of prior art is about 50%, and essential oil content of the present invention is more than 80%.
