The method is simple and convenient to operate, low in manufacturing cost and suitable for scale production.

Description

A kind of method of purification of osmanthus essential oil
Technical field
The invention belongs to technical field of fine, relate to a kind of method of purification of osmanthus essential oil.
Background technology
Plants essential oil is the distinctive aromatoising substance of extraction plant, is taken from herbal flower, leaf, root, bark, fruit, seed, resin etc. and extract with distillation, squeezing mode.Because essential oil-fumigation volatility is high, and molecule is little, be easy to be absorbed by the body, and energy rapid permeability people intracorporeal organ, unnecessary composition is excreted, whole process only needs several minutes, and the fragrance of plant itself, the also secretion of direct Stimulation of The Brain pendant, ferment and hormone secretion etc., function in balanced body, plays the effect of beauty and skin care.But from the natural matters such as fresh flower, extract that plants essential oil cost is high, purity is low traditionally, be difficult to meet the need of market.
Summary of the invention
The object of this invention is to provide a kind of method of purification of osmanthus essential oil.
In order to realize object of the present invention, the present invention is by following scheme implementation:
A method of purification for osmanthus essential oil, comprises the following steps:
(1) clean: choose fresh sweet osmanthus, clean with clean water, pulverize;
(2) ultrasonic: the 30-70% alcoholic solution adding 50-100 times of sweet osmanthus weight in crushed material, ultrasonic 30-90 minute;
(3) extract: the solution after ultrasonic is added separating funnel, adds organic extractant simultaneously, vibration mixing 3-10 minute, leaves standstill and isolates organic phase after 5-15 minute;
(4) rectifying: put into precise distillation tower by extracting the organic phase that obtains, the impurity in vacuum precision distillation removing organic phase, obtain purity higher than 99% essential oil.
Preferably, described alcoholic solution is any one in ethanol, Virahol, butanols.
Preferably, described its frequency ultrasonic is 50-200KHz.
Preferably, described its power ultrasonic is 500-1000W.
Preferably, the volume of described organic extractant be ultrasonic after liquor capacity 1-3 doubly.
Preferably, described organic extractant is any one in ethyl acetate, sherwood oil, methylene dichloride, normal hexane, normal heptane.
Preferably, described precise distillation tower is filled with high efficiency separation filler.
Preferably, described high efficiency separation filler is any one in metal sheet corrugated regular filler, wire cloth structured packing, grid packing, Impulse packing.
Preferably, described vacuum precision distillation is continuous still battery.
Advantage of the present invention is:
(1) the essential oil purity extracted of the present invention is higher than 99%, best in quality;
(2) the present invention prepares highly purified essential oil is Nantural non-toxic product, and can be applied to makeup, medicine and other fields, market outlook are good;
(3) the present invention's solution reagent used can reclaim and reuse, and does not produce discarded waste liquid;
(4) easy and simple to handle, the low manufacturing cost of the present invention, is applicable to large-scale production.
