Embodiment
Embodiment 1
Embodiment one: the preparation of plants essential oil
Get dry lavender, daphne odera, curcuma zedoary, tarragon and camphortree leaf respectively, extract with supercritical carbon dioxide low temperatural extraction, concrete steps are as follows: cleaned up by each raw material respectively and after fragmentation, put into extractor, improve the pressure of extractor and remain on uniform temperature, thus making CO
2liquefaction; At supercritical liq CO
2in continuous extraction process, the grease constituents in raw material is dissolved in liquid CO
2in, become mixed solution and flow away, and be insoluble to CO
2solid slag be then trapped in extractor; The mixed solution obtained flows in splitter, makes CO through cooling, step-down
2generating gasification, grease constituents ooze out, thus realize Oil-gas Separation, wherein gas CO
2recycling use, grease constituents is trapped in splitter to be removed; Receive the grease constituents in splitter, filter with after anhydrous sodium sulfate drying, after refining, obtain the essential oil of each raw material.
Embodiment two: the preparation of essential oil clathrate
Take beta-schardinger dextrin-(through 50 DEG C of dry 2h) and put into conical flask in right amount, then add appropriate distilled water, heating for dissolving, make beta-schardinger dextrin-saturated aqueous solution.After cooling, be placed on magnetic stirring apparatus, slowly add the equal-volume mixed solution of above-mentioned essential oil at a certain temperature, stir inclusion certain hour (2g), leave standstill, refrigeration 24h filters.Wash with the ethanol of 100mL 95%, filter, hang, in vacuum drying chamber, 40 DEG C of dry 2h, obtain inclusion compound.
Test example, mosquito repellent are tested
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 table 1:
Wherein: experimental group 1 is mixed essential oil group; Experimental group 2 is essential oil clathrate groups; Positive controls is repellent amine crude oil; Blank group: absolute ethyl alcohol.
Embodiment four: toxicological experiment
Obtained essential oil of traditional Chinese medicine mixture and essential oil clathrate carry out acute toxicity experience, and result is as follows:
Mouse oral acute toxicity experience: the LD of Mouse oral blend of essential oils
50for 105g/kg, the LD50 of essential oil clathrate is 115g/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.The LD of this essential oil of traditional Chinese medicine
50higher than 21 times of nontoxic standard, be therefore judged to be nontoxic.
When understanding, above-mentioned embodiment is only that illustrative illustrates, for those of ordinary skills, can be improved according to the above description or convert, and all these improves and convert the protection domain that all should belong to claims of the present invention.
