Product effectiveness testing
The bacteriostatic effect of the single cinnamon essential oil, tea tree essential oil and liquorice essential oil, the essential oil compositions prepared in the examples 1-2 and the comparative examples 1-2 is examined by taking staphylococcus aureus as a test bacterium.
Determination of the inhibition zone: absorbing 200 μ L of the suspension liquid (10) by using a paper diffusion method6CFU/mL) to a solid medium (4.5g nutrient broth, 5.0g agar powder, and distilled water to a constant volume of 250.00mL) to make a plate containing bacteria. Filter paper sheets (diameter 6mm) were laid flat on the medium. The concentration of the above essential oil or essential oil composition was diluted to 20% (v/v) with 50% ethanol, respectively, and then dropped into 10. mu.L onto a filter paper sheet. Placing into an incubator at 37 ℃ for 24 h. The size of the zone of inhibition was measured with a vernier caliper, the experiment was repeated 3 times, and the average value was taken. The standard of the sensitivity to the test strain is judged according to the diameter of the inhibition zone, and the inhibition effect is shown in the table 1:
TABLE 1
Figure BDA0002541362790000051
As can be seen from table 1, the essential oil compositions of examples 1 to 2 have larger diameter of the zone of inhibition and better effect of inhibition than the single essential oil and the essential oil compositions of comparative examples 1 to 2.
Indoor bacteriostasis test: the air fresheners of examples 3 to 4 and comparative examples 3 to 5 were used for the bacteriostatic test in the room by the plate sedimentation method. At 25m3The sampling room is placed with 5 nutrient agar plates, the sampling is carried out according to the requirements of indoor air quality standard, the sampling points select four corners and the center in the room, the distance between the sampling points and the ground is 1m, the sampling points are exposed for 60min, and air samples before and after spraying (namely after spraying for 30 min) are respectively collected. And a common agar plate was placed on the table top (1m high) without opening the lid, to serve as a control (control plate should be formed sterile). Then placing the remaining common plates in a constant temperature incubator at 37 DEG CAnd culturing for 24 h. The number of colonies per plate was recorded and the bacterial reduction rate (%) was calculated per nutrient agar plate (number of bacteria before application-number of bacteria after application)/number of bacteria before application 100%, and the results of the in-house bacteriostasis are shown in table 2:
TABLE 2
Figure BDA0002541362790000052
As can be seen from Table 2, the air fresheners prepared in examples 3 to 4 have a higher bacteria reduction rate and a more significant bacteriostatic effect than those prepared in comparative examples 3 to 5. In particular, the air freshener in example 4 (the essential oil composition is 59% of cinnamon essential oil and 41% of tea tree essential oil) has a bacteriostasis effect of 94.44% on natural air bacteria, which is obviously superior to 82.03% of the bacteriostasis rate of the air freshener in comparative example 5 (a commercially available air freshener), and the air purification effect is obviously improved. The experiments show that the three essential oils are mixed according to a proper proportion, so that an obvious synergistic antibacterial effect can be realized, and the natural plant essential oil can not cause harm to the health of a human body, and can be used for producing an air freshener product with environmental protection, safety and good antibacterial effect.
