Herba Cymbopogonis Citrari (Cymbopogon citratus) another name lemon grass (Cymbopogon citratus), also known as Herba Cymbopogonis Citrari, for standing grain originally
Section (Graminaeae) Cymbopogon (Cymbopogon) herbaceos perennial.Plant is high
40～60cm, bar is thinner and more delicate, and in shape of growing thickly, blade tip is the longest and the narrowest, and strain shape is graceful fluffy, simultaneously
Also having the feature seeing flower, its florescence, in autumn Summer Solstice morning, spends green, in cone inflorescence.
Its primary growth in China Guangxi, Hainan, Yunnan, Fujian, the area such as Taiwan, Guangdong, especially
Must relatively early in Taiwan Herba Cymbopogonis Citrari industry development.The Malaysia of south east asia, Vietnam, Thailand,
All there are plantation in the countries such as India, and additionally also there are establishing in large scale in South America, some countries in Africa.
Herba Cymbopogonis Citrari is green in medicine, daily use chemicals, essence and flavoring agent, cosmetics, feed additive and gardens
Change industry and there is the widest purposes.Herba Cymbopogonis Citrari is the dulcet Ornamental Grasses of a kind of tool, can be used for garden
Woods landscape planting.Herba Cymbopogonis Citrari blade of grass is direct-edible, plays flavor and enhancing flavor aodorization as seasoning food materials
Effect.Herba Cymbopogonis Citrari dry product also can be as the direct soaked use of Folium Camelliae sinensis, it is possible to other Folium Camelliae sinensis one
Play collocation to use, be a kind of good health tea raw material.Herba Cymbopogonis Citrari can be as natural plant feed
Additive, ethereal oil contained by Herba Cymbopogonis Citrari can transfer or activate body endogenous anti-oxidative
Point, enhancing body removes the ability of free radical, weakens the degree of lipid peroxidation, thus improves
The antioxygenic property of animal.
Herba Cymbopogonis Citrari herb can be used as medicine, and has a curative effect of dispelling wind to relieve the exterior syndrome, eliminating blood stasis and smoothing collaterals, also deodorization,
The function of sterilization.Having been described in GUYAO book, Herba Cymbopogonis Citrari can be controlled headache, only abdomen, have a stomachache, controls
Tibia pain numbness, the wet pantalgia of wind and cold etc..Numerous studies show both at home and abroad, and Herba Cymbopogonis Citrari has
Pain relieving, blood pressure lowering, diuresis, effect of suppression tumor, can be used for the exploitation of medical product.Herba Cymbopogonis Citrari
Quintessence oil has the effect significantly suppressing tumor, anti-cancer, its rich in bioactive substance have
Good Antimicrobial preservative function, can be used for that natural antibacterial is anticancer, antioxidation and antiseptic and inhibiting bacteria function produce
The exploitation of product.
Present Domestic is mainly reflected in for the extracting method of plants essential oil: steam distillation,
Organic solvent extractionprocess, supercritical fluid extraction, milling process and absorption method.Said extracted side
The plants essential oil that method is obtained is crude product, all needs subsequent treatment could obtain planting of higher purity
Thing quintessence oil.
Summary of the invention
It is an object of the invention to the deficiency for traditional extraction technology, it is provided that a kind of high-purity Herba Cymbopogonis Citrari
The preparation method of grass quintessence oil.Tradition vapor distillation extraction method is distilled by the present invention with modern molecular

(2) molecular distillation partition method: the Herba Cymbopogonis Citrari crude oil prepared in step (1) is passed through secondary
Molecular distillation is purified separation, obtains highly purified Herba Cymbopogonis Citrari quintessence oil；Twice molecular distillation
Vacuum is 0.1～1MPa, and knifing rotating speed is 100～200r/min, and chilling temperature is-20～-10
DEG C, wherein the heating-up temperature of a molecular distillation is 40～60 DEG C, the heating of quadratic component distillation
Temperature is 60～80 DEG C.
In technique scheme, in described step (1), solid-to-liquid ratio is 1:8～1:16, soak time
Being 2～3h, heating-up temperature is 100～160 DEG C, and condensate temperature is 4～10 DEG C, and distillation time is
2～4h.
In technique scheme, in described step (1), Herba Cymbopogonis Citrari raw material is for without cutting off and breaking
Broken whole strain Herba Cymbopogonis Citrari, and moisture content is 40～60%.
In technique scheme, the molecular distillation in described step (2) can be at two points
Sub-distillation equipment series connection formed two-stage series molecular distillation equipment on carry out, it is also possible to be
Distill at twice on same molecular distillation equipment.
It is an advantage of the current invention that:
First, in extracting method of the present invention, Herba Cymbopogonis Citrari raw material does not passes through to shear and break process,
Can effective improving product yield；
Second, this extracting method and separation method are pure physical method, it is not necessary to organic solvent,
Can be good at protection and extract quintessence oil not by other solvent contaminations；
3rd, the present invention uses molecularly distilled separating-purifying, simple to operate, separating rate fast,
Vapo(u)rizing temperature is relatively low, can effectively prevent extract to be heated oxidation Decomposition, it is to avoid because heated time is long
And cause some decomposition of components or polymerization, substantially increase work efficiency and product yield.
