Abstract
The invention relates to the field of essential oil preparation, in particular to a method for extracting essential oil from lemongrass. The method comprises the steps of uniformly mixing lemongrass and sodium chloride, laying aside, adding water for mixing, smashing into lemongrass slurry, performing ultrasonic extraction, separating mixed liquid of filtrate with a centrifugal machine, taking supernate, and performing pressure reduction under a thermostatic water bath condition to remove an organic solvent so as to obtain the essential oil. The method of extracting the essential oil from the lemongrass is short in extraction time and high in extraction rate; after the lemongrass is cured, cell walls and mesenchymal structures of the cell walls produce changes such as local looseness and expansion; the essential oil enters a solvent quickly during subsequent extraction working; the extraction time is greatly shortened; and the extraction rate of the essential oil is increased.
Description
Technical field
The present invention relates to essential oil preparation field and in particular to a kind of lemon-grass extract essential oil method.
Background technology
Lemon-grass is to be grown in a kind of semi-tropical cogongrass spices, and lemon-grass gives out a kind of lemon of natural strong in itself
Fragrance, has the special efficacy promoted the sexual maturity with stomach ventilation, restoring consciouness.Tool antibacterial ability, can treat cholera, acute gastroenteritis and chronic abdomen
Rush down, Glycerin contributes to women skin maintenance and is used, containing substantial amounts of vitamin c, be also the good merchantable brand of cosmetology.Adjust oil
Fat is secreted, and is beneficial to oily skin and hair quality, can be added to the water cleaning skin, stimulate circulation.Tradition extracts lemon-grass essence
The method of oil, recovery rate is low.
Content of the invention
The present invention provides a kind of recovery rate method that high lemon-grass extracts essential oil.
The technical solution adopted in the present invention is:
A kind of method that lemon-grass extracts essential oil, comprises the following steps:
(1) pluck fresh lemon-grass, in lemon-grass: the part by weight of sodium chloride is 1: 0.23-0.34 ratio mixing, mixes
Close and uniformly place 60-100 hour afterwards, and repeatedly stirred mixing, then press lemon-grass: the part by weight of distilled water is 1: 2-
3.5 ratio adds water after mixing, is broken into lemon-grass slurries；
(2) extract: add the rosemary of lemon-grass weight 1-3%, the extractant of 3-5% in lemon-grass slurries, adopt
Ultrasonic extraction 30-50 minute, extracts and is filtered after terminating, and collects filtrate, adds the second that mass concentration is 80-90% in filter residue
Alcoholic solution, repeats above-mentioned ultrasonic extraction and filter operation twice, merges all filtrates；
(3) mixed liquor of filtrate is carried out with centrifuge separating, take supernatant, decompression removal under the conditions of water bath with thermostatic control has
Machine solvent, obtains essential oil.
Extractant described in step (2) is 30-60 degree benzin.
Compared with the prior art, beneficial effects of the present invention are as follows:
The method extracting essential oil from lemon-grass of the present invention, extraction time is short, and recovery rate is high, after lemon-grass is pickled, carefully
Cell wall and its interstitial structure produce the changes such as the loose, expansion of local, so that essential oil during follow-up extraction work is quickly entered into
In solvent, substantially reduce extraction time, improve the recovery rate of essential oil.
Specific embodiment
The present invention is further illustrated with reference to embodiments, but the present invention is not limited only to these embodiments, not
On the premise of departing from present inventive concept, any improvement made is within the scope of the present invention.Embodiment 1
