Technical field
The present invention relates to extraction of essential oil field, especially a kind of method extracting eucalyptus oil.
Background technology
Eucalyptus (Eucalyptus), also known as eucalyptus globolus tree, is the general designation of Myrtaceae eucalyptus plant.Evergreen high megaphanerophyte, about more than 600 plant.Evergreen plant, has the phenomenon that periodic dead leaf comes off in 1 year, large multi items is high megaphanerophyte, and minority is dungarunga, in seldom frutescent.Shape of tree-crown has steeple shape, racemosus shape and weeping branch shape etc.Current, eucalyptus branch, Ye Zhongke extract eucalyptus oil, the main chemical compositions of eucalyptus oil is 1,8-eucalyptol, α-thujene, α-pinene, amphene, beta-pinene, Paracymene, ocimene, terpinolene, α-phellandrene, α-terpinene, limonene, β-caryophyllene, geranial, nerolidol, phantol, a trans pinocarveol, loose eucalyptol, α-eucalyptol etc.Containing the eucalyptus oil of 2-5% in folium eucalypti, eucalyptus oil not only has the smell of fragrance, or a class bioactive ingredients, has the effect of antibacterial, anti-inflammatory, anticorrosion and desinsection mosquito repellent, is widely used in field of medicaments at present.
The extracting method of eucalyptus oil is mainly steam distillation, there is the problems such as low, the consuming time length of extraction yield, product purity be low in existing water vapour, in recent years, also report is had to use supercritical carbon dioxide process, supersonic method, microwave digestion method to extract eucalyptus oil, but it is high to there is equipment cost in this meter kind method, is difficult to realize suitability for industrialized production.
Summary of the invention
The object of the invention is to extract Problems existing for existing eucalyptus oil, a kind of method extracting eucalyptus oil is provided.Not only extraction yield is high for the method, product purity is high, also has that cost is low, consume energy low, the advantage such as extraction time is short.
In order to realize above object, the present invention is achieved by the following technical solutions:
Extract a method for eucalyptus oil, comprise the following steps:
(1) mechanical activation: dried in the shade by folium eucalypti, adds in agitating ball mill, and under rotating speed is 300-500r/min, mechanical activation 3-5min, obtains eucalyptus powder;
(2) soak: above-mentioned eucalyptus powder is added retort, then adds cellulase and water, the weight of described cellulase is eucalyptus powder weight 0.5-0.8%, make water just steep eucalyptus powder with slabstone pressurization, soak 2-3h at normal temperatures, obtain extracting solution;
(3) distill: pass into water vapour from the bottom of retort and extracting solution is heated, extract 1-1.5h after extracting solution boiling, obtain mixing steam;
(4) condensation: mixing steam obtained above carries out condensation through condenser, obtains oil-water mixture after condensation;
(5) oily water separation: the oil-water mixture that condensation obtains carries out oily water separation through water-and-oil separator, obtains the thick oil of folium eucalypti and water;
(6) extract: the thick oil of the folium eucalypti obtained extracts through extractor again, after layering, separates upper strata and is eucalyptus oil.
A kind of the above method extracting eucalyptus oil, step (1) is dried in the shade by folium eucalypti to make its water content be 8-10%.
A kind of the above method extracting eucalyptus oil, described agitating ball mill is agitated ball mill.
A kind of the above method extracting eucalyptus oil, the oil yield of described eucalyptus oil is 2.5-3.3%.
A kind of the above method extracting eucalyptus oil, described eucalyptus oil purity reaches more than 98%.
Compared with prior art, the beneficial effect that the present invention obtains is:
(1) the present invention is before distillation extraction eucalyptus oil, by folium eucalypti first through mechanical activation process, folium eucalypti is destroyed the cell walls of plant by mechanical activation under the mechanical force such as friction, collision, impact, shearing, and make grain refine, make the essential oil in folium eucalypti be more prone to extract, thus improve oil yield.
(2) the present invention is before distillation extraction eucalyptus oil, folium eucalypti first uses cellulase and water soaking, the cellulose skeleton of composition cell walls can be degraded into glucose by cellulase step by step, and then destroy cell wall skeleton structure, eucalyptus oil is more easily extracted, not only increase oil yield, also shorten the distillation extraction time.
(3) oil yield of eucalyptus oil of the present invention is 2.5-3.5%, and existing wet distillation method oil yield only reaches and is about 2%.
(4) the thick oil after oily water separation of the present invention, first through extracting and separating, improves the purity of product, and the eucalyptus oil purity obtained reaches more than 97%, and existing extracting method purity generally only reaches 90%.
(5) the inventive method also have simple to operate, extraction time is short, low cost and other advantages, is applicable to suitability for industrialized production.
