Abstract
The invention discloses a method for extracting lavender essential oil and relates to the technical field of plant essential oil extraction. The method comprise the following specific steps: picking fresh lavender, cleaning fresh lavender with clean water, naturally drying in air, adding a sodium chloride solution, and soaking; transferring to a distillation device, carrying out atmospheric distillation, heating until condensed liquid drops on a glass plate and no oil droplets occur, and stopping the distillation; enabling condensed liquid to pass through an adsorption column filled with the activated carbon; adding an ethanol solution into the activated carbon adsorption column, and leaching oil in the activated carbon adsorption column; carrying out vacuum distillation on leach liquid to obtain lavender essential oil. The lavender essential oil has no toxic and side effects on the human body.
Description
Technical field
The present invention relates to plants essential oil extractive technique field, especially a kind of extracting method of Herba Lysimachiae foenumgraeci quintessence oil.
Background technology
Herba Lysimachiae foenumgraeci quintessence oil is to be refined and formed by lavandula angustifolia, can be clearing heat and detoxicating, and cleaning skin, controls oil content, freckle removing and whitening, the tender skin of anti-wrinkle, eye haustra-dsipelling black eye, also can promote damaged tissue regeneration recovery to wait skin-protecting function.Herba Lysimachiae foenumgraeci quintessence oil has sedation effect to heart, can reduce hypertension, pacify palpitaition, helpful for insomnia.At present, conventionally utilize the low boiling point organic solvents such as sherwood oil, ether to extract Herba Lysimachiae foenumgraeci quintessence oil, this method is simple to operate, but the contained objectionable constituent of these organic solvents remain in product, to human body toxic side effect.
Summary of the invention
The extracting method that the object of this invention is to provide a kind of Herba Lysimachiae foenumgraeci quintessence oil, the prepared Herba Lysimachiae foenumgraeci quintessence oil of this method has no side effect to human body.
In order to address the above problem, the technical solution used in the present invention is: the extracting method of this Herba Lysimachiae foenumgraeci quintessence oil, comprises the following steps:
A, win fresh lavandula angustifolia, clear water is cleaned, and naturally dries, and adds sodium chloride solution, soaks 2 hours～3 hours; Wherein, the concentration of described sodium chloride solution is 20%～25%;
B, proceed to water distilling apparatus and carry out air distillation, be warming up to 100 ℃～105 ℃, drop on sheet glass to cool lime set, while occurring without oil droplet, stop distillation;
C, by described cool lime set by the adsorption column of gac is housed;
D, in described active carbon adsorption column, add ethanolic soln with the oil content in lixiviate active carbon adsorption column; Wherein, extracting times is 5 times ~ 8 times, and the time of each lixiviate is 3 hours ~ 4 hours;
E, the vat liquor that step D is obtained carry out underpressure distillation; Wherein distilling pressure is 0.1 kPa～1.0 kPas.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
Technique of the present invention is simple, and cost is low, and lixiviate organic solvent used is ethanolic soln, and it volatilizees thoroughly in leaching process, in product without alcohol residue, to human body toxicological harmless effect.This Herba Lysimachiae foenumgraeci quintessence oil can be used in prepares makeup, washing articles for use, medicine etc., and tool has been widely used.
