Abstract
The invention discloses a kind of method of wormwood extraction of essential oil, methods described comprises the following steps：1), fresh wormwood is cleaned up, wormwood 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 wormwood essential oil；The method of the present invention is first cooked using pressure cooker, and the active ingredient of wormwood 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 wormwood extraction of essential oil.
Background technology
Wormwood, alias：Xiao Mao, ice platform, hold back grass, fragrant Chinese mugwort, Chinese mugwort, Ai Xiao, argy wormwood, argy wormwood, fluffy ligusticumic, Chinese mugwort, moxibustion grass, doctor it is careless,
Yellow grass, moxa etc..Perennial herb slightly has enhanced aroma into suffruticose, plant.Stem list is raw or a small number of, and brown or ash are yellowish-brown
Color, base portion slightly lignifying, top Bi matter, and have a small number of short branches, leaf ground paper matter, led to above by canescence pubescence, base portion
Often without pseudostipule or minimum pseudostipule；Upper leaf partly splits with bract leaf pinniform, capitulum ellipse, corolla tubulose or high pin
There is gland point cup-shaped, outside, and flower pesticide is narrow linear, and style and corolla be near isometric or slightly longer than corolla.Achene long avette or Long Circle.Flower
The fruiting period 9-10 months.All herbal medicine, have Wen Jing, dry, cold dispelling, hemostasis, anti-inflammatory, relieving asthma, cough-relieving, the effect such as antiabortive, antiallergy.Chinese mugwort
Leaf, which dries, to be smashed to pieces " moxa ", and moxa stick processed can make the raw material of " ink paste " for moxa-moxibustion again；By the extracts active ingredients of wormwood, 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 wormwood essential oil, 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 wormwood extraction of essential oil.
Technical scheme provided by the invention is：
A kind of method of wormwood extraction of essential oil, methods described comprise the following steps：
1), fresh wormwood is cleaned up, wormwood 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 wormwood essential oil.
Preferably, the water added in step 1) is 5 times of weights of wormwood.
Preferably, the water added in step 2) is 2 times of weights of filter residue.
Preferably, the temperature that wormwood 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 wormwood 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.
