Description
Technical field
The present invention relates to pest repellant, particularly mosquito-repellent, its preparation method and application thereof.
Background technology
Chinese herbal medicine is applied to repel insects in existing long history and the rich experience of China, is worth arrangement, excavates and exploitation.Like the tomb of Han dynasty in Mawangdui, Changsha, though experience the very long years, most of clothes is excellent, and one of its reason is that a large amount of fragrant Chinese herbal medicines is arranged in the dead's funerary objects.Mostly domestic and international employed mosquito-repellent is old kinds such as DETA (basic toluamide between diethyl), O-phthalic ester at present.
Summary of the invention:
The technical problem that solves
The object of the present invention is to provide a kind of mosquito repellent spectrum wide, aging time is long, avirulence, and raw material is easy to get, the mosquito-repellent that technology is easy.
Technical scheme
A kind of mosquito-repellent is characterized in that comprising by mass fraction
1～5 part of Paeonol
1～5 part of methyl vanillin
1～5 part of Ethyl vanillin
0.5～2.0 part of vanillic aldehyde
80～100 parts of 70% ethanol
As a kind of optimal way, above-mentioned component and ratio also can be
1～3 part of Paeonol
1～3 part of methyl vanillin
1～3 part of Ethyl vanillin
0.5～1.5 part of vanillic aldehyde
80～100 parts of 70% ethanol
As the above component of a kind of optimal way and ratio also can for
1～5 part of Paeonol
1～5 part of methyl vanillin
1～5 part of Ethyl vanillin
0.5～2.0 part of vanillic aldehyde
0.1～2.0 part of asiaticosid
80～100 parts of 70% ethanol
As the described mosquito-repellent of best optimization mode, it is 2: 2: 2 by the proportional quantity of the described Paeonol of mass ratio, methyl vanillin, Ethyl vanillin and vanillic aldehyde: 1.
Savory and the mosquito-repelling function of vanillic aldehyde, methyl vanillin and Ethyl vanillin itself, but unite the effect of having used mutual synergy, and can consolidate fragrant effect, make that fragrance and mosquito repellent are lasting.Paeonol plays main repelling effect; Asiaticosid has the effect of the ultraviolet radiation of preventing.
The preparation method of described mosquito-repellent; It is characterized in that comparing 1～5 part of Paeonol, 1～5 part of methyl vanillin, 1～5 part of Ethyl vanillin and 0.5～2.0 part of vanillic aldehyde, add 80～100 part of 70% ethanol and mix, stir, be dissolved into finished product by mass parts.
Preparation method as the described mosquito-repellent of a kind of optimal way; It is characterized in that by mass parts adding 100 part of 70% ethanol and mixing, stir, dissolve finished product than with 0.1～2.0 part of 1～5 part of Paeonol, 1～～5 part of methyl vanillin, 1～5 part of Ethyl vanillin and 0.5～2.0 part of vanillic aldehyde and asiaticosid.
Be mixed with aerosol or paint according to the above ratio, can spray with air in or directly smear with human epidermal in.Also can make emulsion, add solid content, the mosquito repellent time is lasting during use.
Beneficial effect
1, the mosquito repellent spectrum is wide, and aging time is long, and raw material is easy to get, the mosquito-repellent that technology is easy.The mosquito repellent spectrum comprises aedes albopictus, culex, anopheles.
2, toxicity is low: Paeonol is the active ingredient of the common Chinese medicine root bark of tree peony, and vanillic aldehyde, methyl vanillin and Ethyl vanillin are flavoring essence; Through the mouse toxicity test, get mouse LD
50(mg/kg) oral 3430-4900.
3, adopt the common Chinese medicine component among the present invention, so skin is not had spread effect or side effect.
4, adopt asiaticosid among the present invention, can play the effect that prevents ultraviolet radiation.
5, the Paeonol in these article raw material not only has calmness, analgesic nervous centralis effect, and also has effects such as anti-inflammation, step-down.Edible chinese cymbidium have solid perfume (or spice) and synergistic effect.
6, the present invention so use back indoor climate fragrance graceful, has the effect of cephalocathartic and prevention respiratory tract infection owing to be adopted as fragrance component.
