[0052] Performance Testing The natural essential oil compositions obtained in Examples 1-3 and Comparative Examples 1-7 were made into aromatherapy with a content of 50%, and used as samples; Anti-anxiety test: 110 test mice were taken and divided into 11 groups of 10 mice each. 10% sodium sulfide was used to remove hair on the back of the mice's buttocks 1×1 cm, and they were randomly divided into a control group (normal saline). The other 10 groups were air-conditioned for 7 days with the samples of Examples 1-3 and Comparative Examples 1-7, and air-conditioned for 1 hour each day. Then the tail of the mouse was fixed to the edge of the stand with adhesive tape, and it was hung upside down in a box (30cmX25cmX15 cm), with the head about 5cm from the bottom of the box. The mouse activity curve was displayed by the BL420E+ biological function experiment system software. The immobility time of the mouse within 6 minutes was observed and recorded, and the test results are shown in Table 1.
[0053] Table 1 Test results
[0054] Note: “*” p<0.01, “※” p<0.05
[0055] As can be seen from Table 1, compared with the control group, Examples 1-3 have very significant antianxiety effects, and Comparative Examples 1-7 have significant antianxiety effects. It can be seen that the antianxiety effects of Examples 1-3 are better than those of Comparative Examples 1-7; due to the coordination between the various components in Examples 1-3, it is beneficial to secrete dopamine, serotonin and endorphins, and reduce cortisol, from the fresh lemon fruit fragrance accompanied by sweet and elegant floral fragrance, to the tea fragrance, and finally to the woody fragrance, to achieve a multi-layered sense of fragrance, thereby better guiding the process of smell to the brain, and the body also enters a state of relaxation from shallow to deep, thereby effectively relieving anxiety, while in Comparative Examples 1-7, due to the lack of ingredients, the fragrance level is affected, thereby affecting the transmission of the sense of smell and reducing the anti-anxiety effect.
[0056] Sniff test: 100 volunteers with anxiety problems were selected and divided into 10 groups, with 10 people in each group. The samples of Examples 1-3 and Comparative Examples 1-7 were used for sniffing for 20 minutes respectively. The heart rate and systolic blood pressure (SBP) were measured using SPSS 26.0. The average value of each group was taken. The test results are shown in Table 2.
[0057] Table 2 Test results
[0058] From the analysis of Table 2, it can be concluded that the changes in heart rate and systolic blood pressure before and after sniffing of Examples 1-3 are greater than those of Comparative Examples 1-7, among which the changes in heart rate and systolic blood pressure of Example 2 are greater. Comparative Examples 1-7 lack any one of camellia essential oil, lemon essential oil, jasmine essential oil, white tea extract, fir essential oil, guaiac wood essential oil and magnolia essential oil, and the changes in heart rate and systolic blood pressure will be reduced, indicating that the effect of relieving anxiety is reduced.
[0059] Caryophyllene content test: The Magnolia grandiflora essential oils prepared in Examples 1-3 and Comparative Examples 8-9 were used as samples, and GC-MS analysis was performed on the samples. The results are shown in Table 3.
[0060] Table 3
[0061] It can be concluded from the data in Table 3 that the content of caryophyllene in Examples 1-3 is greater than that in Comparative Examples 8-9. In Comparative Example 8, only one extraction with n-hexane is used, resulting in insufficient extraction. In Comparative Example 9, no natural vitamin E is added, and caryophyllene is oxidized to reduce its content. Therefore, the reduction in the content of caryophyllene in Comparative Examples 8-9 will lead to a weakened aroma and a change in odor.
