Abstract
The invention discloses a kind of method of oil of Cymbopogon winterianus extraction, methods described comprises the following steps：1), fresh lemongrass is cleaned up, lemongrass drying, chopping, addition water are boiled 12 hours in pressure cooker, are filtrated to get the first filtrate and filter residue；2) filter residue of step 1, is added into water to boil in pressure cooker 12 hours, is filtrated to get the second filtrate；3), the first filtrate and the second filtrate are merged and are put into the reactor of distillation, is distilled, collects distillate；4), the reactor for slipping out liquid and being put into distillation is distilled again, obtains oil of Cymbopogon winterianus；The method of the present invention is first cooked using pressure cooker, and the active ingredient of lemongrass is separated out, then extracts by second distillation to obtain essential oil, the inventive method is simple to operate, and extraction time is short, and cost is low, solvent is free of using water distillation extraction, the essential oil purity that the present invention extracts is high, no solvent residue.
Description
Technical field
A kind of plants essential oil extractive technique field of the present invention, and in particular to method of oil of Cymbopogon winterianus extraction.
Background technology
Lemongrass is the general designation of about 55 kinds of fragment plants of grass family Cymbopogon, also known as lemon-grass, be common vanilla it
One.Because there is citris aromas, therefore the lemon grass (Cymbopogon citratus) that is otherwise known as.It is rather good to treat rheumatism effect, treats antimigraine, it is anti-infective, improve digestion
Function, deodorization, expelling parasite.It is anti-infective, Cress, nurse one's health greasy unclean skin.Freshness is assigned, recovers balance of body and spirit.It is virtue
The most wide essential oil of purposes in fragrant therapy and therapy.It can also be used for interior and work as aromatic；By the extracts active ingredients of lemongrass, system
Into essential oil, the technique extracted at present is mainly extracted using organic solvent, or means of supercritical extraction, after organic solvent extraction, is had
Solvent remains the quality that can cause oil of Cymbopogon winterianus, and means of supercritical extraction cost is high.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art part, there is provided a kind of method of oil of Cymbopogon winterianus extraction.
Technical scheme provided by the invention is：
A kind of method of oil of Cymbopogon winterianus extraction, methods described comprise the following steps：
1), fresh lemongrass is cleaned up, lemongrass drying, chopping, addition water are boiled 1-2 hours in pressure cooker, filtered
Obtain the first filtrate and filter residue；
2) filter residue of step 1, is added into water 1-2 hours is boiled in pressure cooker, be filtrated to get the second filtrate；
3), the first filtrate and the second filtrate are merged and are put into the reactor of distillation, is distilled, collects distillate；
4), the reactor for slipping out liquid and being put into distillation is distilled again, obtains oil of Cymbopogon winterianus.
Preferably, the water added in step 1) is 5 times of weights of lemongrass.
Preferably, the water added in step 2) is 2 times of weights of filter residue.
Preferably, the temperature that lemongrass cooks in step 1) is 100-120 DEG C.
Preferably, the temperature that filter residue cooks in step 2) is 100 DEG C.
Preferably, the temperature of distillation is 100-120 DEG C in step 3).
Preferably, the temperature of distillation is 100-110 DEG C in step 4).
The present invention comprises at least following beneficial effect：
The method of the present invention is first cooked using pressure cooker, and the active ingredient of lemongrass is separated out, then is extracted by second distillation
Essential oil is obtained, the inventive method is simple to operate, and extraction time is short, and cost is low, is free of solvent using water distillation extraction, the present invention carries
The essential oil purity taken is high, no solvent residue.
Further advantage, target and the feature of the present invention embodies part by following explanation, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
