Experimental example 1
Example 1 to 5 gained sample carries out mosquito repellent test, with 95% Metadelphene crude oil (commercially available) for positive control, using ethanol as blank.
With reference to National Standard of the People's Republic of China, the method for indoor harmacological effect evaluation repellant (GB/T17355.10-1998) of agriculture chemical registration hygienic insecticide carries out mosquito repellent experiment.
Attack is tested: growing × and wide × high for putting into the female mosquito of aedes albopictus that 300 4 ~ 5 ages in days are not sucked blood in the mosquito cage of 30cm × 30cm × 60cm.Wipe out after mouse web portion becomes mildewed, hair remover is applied to belly, wipes with paper handkerchief after 5min, clean with tap water, dry with cotton balls.The depilation time should be not long, otherwise can destroy the skin of mouse.Being fixed on by test mice folds up in the plastic plate of mouse, and belly aims at the border circular areas (diameter 2.5cm) being put in hollow out, and four limbs and tail adhesive tape are tightly wound around, and cover skin.Examination mouse is put into mosquito cage 2min, the examination worm coming to stop to fall is that attack is qualified more than 20 persons, and this mouse and this cage mosquito can be used for repellency test.
Mosquito repellent is tested: get 12 mouse and divide 4 groups, with above-mentioned method depilation process.Mouse from (losing hair or feathers) the skin of abdomen that border circular areas (diameter 2.5cm) exposes, uniform application is for the essential oil, the embodiment of the present invention 2 manufactured goods (0.1mL), the Metadelphene crude oil 20 μ L and absolute ethyl alcohol 20 μ L that try essential oil clathrate (0.1g) or equal-volume mixing respectively, examination mouse is put into respectively mosquito cage (having about 300 female mosquitos), observe 2min, record thorn stings the mosquito quantity of mouse, put into mosquito cage at interval of 1h and observe whether have bite by mosquitos, observe 5h altogether, observe 2min at every turn.The mouse of smearing 20 μ L absolute ethyl alcohols with belly makes blank group, observes the attacking ability of mosquito.Calculate the Effective Vate of Protection of each group, computing formula is as follows:
Effective Vate of Protection (%)=(contrast mosquito thorn sting number-be coated with mosquito thorn after test sample to sting number)/blank group mosquito thorn stings number
Experimental result is as follows:
From above result, culicifuge repelling effect of the present invention is far superior to commercially available 95% Metadelphene crude oil.
Experimental example 2
Embodiment 1 to 5 gained sample is carried out acute toxicity experience, and result is as follows:
Mouse oral acute toxicity experience: the LD of Mouse oral embodiment gained sample
50for 105g/kg, 95% be crediblely limited to 159.28g/kg ~ 228.63g/kg.And the toxicity criterion of air freshener is: the anxious malicious LD of Mouse oral
50>=5g/kg, is judged to be nontoxic.Culicifuge LD of the present invention
50higher than 21 times of nontoxic standard, be therefore judged to be nontoxic.
