Description
Technical field
The present invention relates to biomedicine technical field, particularly a kind of cedar oil extracting method and cedar oil culicifuge thereof.
Background technology
Cdear Cedrusdeodara (Roxb) G.Don is the general term that Pinaceae Pianaceae plant cedar belongs to CedrusTrew seeds, extensively distributes in China various places, contains cedar oil in the pine needle of cdear and pine branch.At present, the extraction of cedar oil, has the methods such as distillation and extraction; Extracting process mostly with absolute ethyl alcohol, ethyl acetate, benzinum for solvent, adopt fractional extraction.
Mosquito, flea, bedbug etc. bite, and often cause the symptom such as itch, allergy, also propagate the various diseases such as such as malaria, yellow fever, dengue fever, AIDS, serious threat human health simultaneously.Meanwhile, bite by mosquitos directly or indirectly can bring pressure to human lives, as impact sleep and interference field work.
People are in order to prevent bite by mosquitos, and drive poisoning mosquito, the medicament of production and application is a lot.Pest repellant conventional is in the market mainly chemosynthesis medicine, as organochlorine, organic phosphor, carbamates, expelling parasite amine etc., although these chemicalss can control the quantity of mosquito, but, the harmful side effect as pesticide resistance, non-target target organism toxicosis and environmental pollution and so on can be caused.
Since ancient times, our people just finds that many plants have repelling effect, and in life, use them to carry out mosquito repellent.Because these natural plants are to human non-toxic, side effect, and the mode of action is unique, and mosquito not easily produces resistance.Have been reported point out lemongrass, geranium, lavender, cdear, Verbena officinalis, peppermint, pine, cajeputtree, Chinese cassia tree, rosemary, Xue MingRosma rinus officinalis, thyme, allspice, the plant such as sweet basil and garlic essential oil to mosquito, there is repellent activity.But most method adopting plant sootiness, the method is by raw-material restriction, and easy initiation fire, there is hidden danger, the smog that especially sootiness produces has a strong impact on room air.Chinese patent (number of patent application is 200910148278.2) " mosquito-repelling smearing agent ", is made up of cedar oil, cedar leaves oil, citronella oil, ethanol; Rationally, result of use is good, and production cost is low for this invention formula.
Summary of the invention
The object of the present invention is to provide the cedar oil extracting method that a kind of recovery rate is higher, and application cedar oil culicifuge prepared by the cedar oil that the method is extracted is provided, this cedar oil culicifuge can effective mosquito, and can suppress the bacterium in air, purifies air.
