Abstract
The invention discloses a kind of method of osmanthus essential oil extraction, methods described comprises the following steps：1), fresh sweet osmanthus is cleaned up, sweet osmanthus 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 osmanthus essential oil；The method of the present invention is first cooked using pressure cooker, and the active ingredient of sweet osmanthus 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 osmanthus essential oil extraction.
Background technology
Sweet osmanthus：Also known as sweet-scented osmanthus, rock osmanthus, chain timbers Rhinocerotidae evergreen shrubs or dungarunga, matter heavily fortified point thin skin, leaf oblong face end
Point, to life, do not withered through the winter.Between peanut leaf internal organs, corolla sympetalous four splits, and shape is small, and its kind has gold osmanthus, silver osmanthus, orange osmanthus, bay etc..
Sweet osmanthus is one of ten big flowers of Chinese tradition, integrates greening, beautification, sweetening treatment are viewed and admired and the practical excellent gardens tree having both
Kind, sweet osmanthus clearly can dust-tight, it is dense far to overflow, rate as an unsurpassed one.Especially time midautumn, Cong Gui is in full bloom, when night quiet wheel circle, reward of filling a wine cup for
Osmanthus, Chen Xiang assail the nostrils, Bracing.Colored poem is chanted in ancient Chinese, the quantity for chanting Gui Zhizuo is also rather considerable.From ancient times
Depth is liked by Chinese, is considered as traditional famous flower.The osmanthus flower tea that raw material making is done with sweet osmanthus is special product of China tea, its fragrance
Soft, delicious taste, liked by masses；By the extracts active ingredients of sweet osmanthus, essential oil is made, the technique extracted at present is mainly
Extracted using organic solvent, or means of supercritical extraction, after organic solvent extraction, organic solvent residual can cause the product of osmanthus essential oil
Matter, 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 osmanthus essential oil extraction.
Technical scheme provided by the invention is：
A kind of method of osmanthus essential oil extraction, methods described comprise the following steps：
1), fresh sweet osmanthus is cleaned up, sweet osmanthus 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 osmanthus essential oil.
Preferably, the water added in step 1) is 5 times of weights of sweet osmanthus.
Preferably, the water added in step 2) is 2 times of weights of filter residue.
Preferably, the temperature that sweet osmanthus 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 sweet osmanthus 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.
