Description
Technical field
The present invention relates to the biological medicine technology field, particularly a kind of cedar oil extracting method and cedar oil culicifuge thereof.
Background technology
Cdear Cedrus deodara (Roxb) G.Don is the general term that Pinaceae Pianaceae plant cedar belongs to Cedrus Trew seeds, in China various places, extensively distributes, and in the pine needle of cdear and pine branch, contains cedar oil.At present, the extraction of cedar oil, have the methods such as distillation and extraction; It is solvent that extracting process mostly be take absolute ethyl alcohol, ethyl acetate, benzinum, adopts fractional extraction.
Mosquito, flea, bedbug etc. bite, and often cause the symptoms such as itch, allergy, also propagate various diseases such as malaria, yellow fever, dengue fever, AIDS, serious threat human health simultaneously.Simultaneously, bite by mosquitos can directly or indirectly bring pressure to the human lives, as impact sleep and interference field work.
People, in order to prevent bite by mosquitos, drive the poisoning mosquito, and the medicament of production and application is a lot.Pest repellant commonly used is mainly chemosynthesis medicine in the market, as organochlorine, organic phosphor, carbamates, expelling parasite amine etc., although these chemicalss can be controlled the quantity of mosquito, but, can cause the harmful side effect as the organism toxicosis of pesticide resistance, non-target and environmental pollution and so on.
Since ancient times, China people just find that many plants have repelling effect, and carry out mosquito repellent with them in life.Because these natural plants are nontoxic to human body, side effect, and mode of action uniqueness, mosquito is difficult for producing resistance.Have been reported point out lemongrass, geranium, lavender, cdear, Verbena officinalis, peppermint, pine, cajeputtree, Chinese cassia tree, rosemary, Xue MingRosma rinus officinalis, the essential oil of the plant such as thyme, allspice, sweet basil and garlic has repellent activity to mosquito.But most methods that adopt the plant sootiness, the method is subject to raw-material restriction, and easy initiation fire, has hidden danger, and 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 ", be comprised of cedar oil, cedar leaves oil, citronella oil, ethanol; Rationally, result of use is good for this invention formula, and production cost is low.
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 provide application cedar oil culicifuge prepared by the cedar oil that the method is extracted, this cedar oil culicifuge is mosquito effectively, and can suppress airborne bacterium, purifies air.
The technical solution used in the present invention is a kind of cedar oil extracting method of invention, and its method is as follows:
A, get the raw materials ready: choose fresh or dry cedar needles or pine branch, be ground into 30-60 purpose powders, standby;
B, immersion: standby powder is soaked in that 8-10 doubly measures, that the pH value is 5.0-6.0 hydrochloric acid or sulfuric acid solution, soaks 8-10 hour, become the immersion mixed liquor, standby;
C, enzymolysis: add the complex enzyme that accounts for powder weight 0.6-1.0% in standby immersion mixed liquor, at 40-50 ℃ of enzymolysis 2-3 hour, become enzymolysis liquid, standby; Described complex enzyme is by cellulase: with the glue enzyme, the ratio according to 1:0.4 mixes fruit;
D, extraction: standby enzymolysis liquid is 100 ℃-120 ℃ with hydrodistillation altogether in temperature and extracts 3-4 hours, collect distillate, be cooled to after room temperature carry out oil, moisture from, then use anhydrous sodium sulfate drying, separation, obtain cedar oil.
Simultaneously, providing a kind of cedar oil culicifuge prepared by above-mentioned cedar oil of applying, is to be prepared from by following raw material by weight:
