Description

Technical Field

[0001] The present invention relates to the technical field of aromatherapy, and in particular to a compound essential oil for alleviating anxiety, a preparation method thereof and an application thereof. Background Art

[0002] At present, with the gradual acceleration of the pace of life, the stress level of humans has gradually increased. In particular, mental burdens such as economic problems, work pressure, and family problems may cause serious psychological and emotional stress. When the psychological and emotional stress reaches a certain level, it will lead to emotional tension and the mind being constantly in a tense state, thus disrupting the balance between the organism and its environment. When the human body is in a state of anxiety for a long time, it is very easy to cause symptoms such as insomnia, easy waking, early waking, or difficulty in falling asleep again after waking. And the decline in sleep quality will further worsen the anxiety mood. In such a vicious cycle, it may have a negative impact on the physical health of the human body, such as hair loss, sallow skin, or the body being in a sub-healthy state for a long time, etc.

[0003] In order to improve sleep quality and reduce the negative impact of anxiety on the body, it is necessary for us to take measures to alleviate anxiety. Existing research shows that aromatic plant essential oils have a certain effect of alleviating anxiety. Aromatic plant essential oils can enter the human body through inhalation and other ways, regulate neurotransmitters and receptors related to anxiety in the human body, maintain the balance state between the human body and the environment, and achieve the purpose of alleviating anxiety and improving sleep quality.

[0004] However, the effect of a single essential oil in alleviating anxiety and improving sleep quality is limited. Therefore, different essential oils are often selected and combined in the market to optimize the effect of essential oils in alleviating anxiety and improving sleep quality. However, due to the complex components of essential oils, the functional effects and synergistic effects among the components are all different. The compound essential oil after compounding, that is, the compound essential oil, often hardly has a more obvious effect of alleviating anxiety and improving sleep quality, and may even further increase the excitability of the brain, bringing a negative impact on alleviating anxiety and improving sleep quality. Therefore, it is necessary to further optimize the formula of the compound essential oil to enhance the positive effect of the compound essential oil on alleviating anxiety and improving sleep quality.

[0107] Detection of diffusion ability, stability and improvement of sleep quality:

[0108] Test samples: The compound essential oils of the above examples and comparative examples, and the compound essential oils of the above examples and comparative examples after being placed in an open container in the room for 30 days under the condition of indoor temperature of 28°C and daylight.

[0109] Test personnel: 360 volunteers with the ability to evaluate fragrance and suffering from mental anxiety, divided into 36 groups with 10 people in each group.

[0110] Test method 1: Respectively at 25°C, 10m 2The test samples were opened in a closed space, and the indoor fragrance concentration was evaluated and scored after 15 minutes. The score range was 0-40 points. 39.1-40 points represented good fragrance diffusion effect, 36-39 points represented good fragrance diffusion effect, 32-35.9 points represented acceptable fragrance diffusion effect, 28-31.9 represented fair fragrance diffusion effect, 24-27.9 represented qualified fragrance diffusion effect, and less than 24 points represented unqualified fragrance diffusion effect.

[0113] The above scores are averaged and are shown in Table 2.

[0114] Table 2:

[0115]

[0116]

[0117] Combining Examples 1-13 and Comparative Examples 1-5, it is not difficult to see that Examples 1-13 have good effects of relieving anxiety and improving sleep quality, and Example 1-4 has better stability.

[0118] Specifically combining the analysis of Example 1 and Comparative Examples 1-4, it is not difficult to see that Comparative Examples 1-4 do not contain French lavender oil, Xinjiang lavender oil, cypress oil essential oil, and Virginia cypress oil, respectively, and the effects of relieving anxiety and improving sleep quality in Comparative Examples 1-4 are relatively poor to a certain extent. Therefore, the applicant believes that only the synergistic effect of French lavender oil, Xinjiang lavender oil, cypress oil essential oil, and Virginia cypress oil can better regulate the irritation of the composite essential oil, better comfort the nervous system, and reduce the excitability of the nervous system, thereby achieving the effect of significantly relieving anxiety and improving sleep quality.

[0119] Specifically, by analyzing Example 1 and Comparative Example 5, it is not difficult to see that Comparative Example 5 did not add absolute ylang-ylang oil, Xinjiang sclareol oil, bergamot oil, and eucalyptus oil. To a certain extent, the diffusion effect, anxiety-relieving effect, and sleep quality improvement effect of Comparative Example 5 were inferior to those of Example 1. Therefore, the applicant analyzed that only the combination of absolute ylang-ylang oil, Xinjiang sclareol oil, bergamot oil, and eucalyptus oil can further enhance the anxiety-relieving effect of the compound essential oil and improve the diffusion ability of the compound essential oil, enabling the compound essential oil to fill the use space faster and better and enhancing the use experience of the compound essential oil.

[0120] Specifically, by analyzing Example 1 and Examples 5-9, it can be seen that in Examples 5-9, patchouli oil, citronella oil, cubeb oil, and acorus tatarinowii essential oil were not added simultaneously or not added at all. Example 1 had better stability. The experimental results showed that even when the compound essential oil of Example 1 was placed open at room temperature of 28°C for 30 days, it still had good activity and showed good effects of relieving anxiety and improving sleep quality externally. Thus, it can be seen that further adding patchouli oil, citronella oil, cubeb oil, and acorus tatarinowii essential oil to the compound essential oil can significantly improve the stability of the efficacy of the compound essential oil and significantly extend the effective use duration of the compound essential oil.

[0121] Specifically, by analyzing Example 1 and Examples 10-13, it can be seen that in Example 10, commercially available sweet almond oil was used. In Example 11, lysozyme was not added during the preparation of sweet almond oil. In Examples 12-13, the lysozyme was not used within the proportion range of this application. To a certain extent, the diffusion effect and stability of Examples 10-13 were inferior to those of Example 1. Therefore, it can be analyzed that by adopting the enzymatic hydrolysis extraction method and selecting a compound enzyme within a special proportion range when extracting sweet almond oil in this application, the diffusion ability of the compound essential oil can be further optimized, the stability of the compound essential oil can be improved, and the use experience of consumers can be further enhanced.

[0122] This specific embodiment is only an interpretation of this application and does not limit this application. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as they are within the scope of the claims of this application, they are protected by the patent law.
