Embodiment 1
[0035] Preparation of celery seed volatile oil:
[0036] 1. Take 1 kg of air-dried celery seeds, crush them with a mechanical grinder for 60 seconds, pass through a 20-mesh sieve, and steam distill for 6 hours to obtain a volatile oil-material liquid with a material-to-liquid ratio of 1:10.
[0037] 2. Collect the obtained volatile oil liquid and dry it through anhydrous sodium sulfate to obtain celery seed volatile oil (extraction rate 5.86%).
[0038] 3. Store the obtained celery seed volatile oil in a refrigerator at 4°C.
[0039] The celery seed volatile oil obtained through the above steps can be further freeze-dried to obtain celery seed volatile oil freeze-dried powder.
Embodiment 2
[0041] Preparation of cumin volatile oil:
[0042] 1. Take 1kg of air-dried fennel, crush it with a mechanical grinder for 30 seconds, pass it through a 40-mesh sieve, and steam distill it for 3.5 hours to obtain a volatile oil-material liquid with a material-to-liquid ratio of 1:5.
[0043] 2. Collect the obtained volatile oil and dry it with anhydrous sodium sulfate to obtain cumin volatile oil (extraction rate: 5.52%).
[0044] 3. Store the obtained fennel volatile oil in a refrigerator at 4°C.
[0045] The fennel volatile oil obtained through the above steps can be further freeze-dried to obtain the freeze-dried powder of the fennel volatile oil.
Embodiment 3
[0047] Preparation of Ayurveda volatile oil:
[0048] 1. Take 1 kg of air-dried Ayurveda, crush it with a mechanical grinder for 90 seconds, pass it through a 20-mesh sieve, and steam distill it for 6 hours to obtain a volatile oil-material liquid with a material-to-liquid ratio of 1:15.
[0049] 2. Collect the obtained volatile oil stock liquid and dry it with anhydrous sodium sulfate to obtain the volatile oil of Ayurveda sativa (extraction rate is 5.26%).
[0050] 3. Store the obtained Ayurveda volatile oil in a refrigerator at 4°C.
[0051] The Ayurveda volatile oil obtained through the above steps can be further freeze-dried to obtain a freeze-dried powder of the Ayurveda volatile oil.

Abstract
The invention discloses a preparation method for antibacterial volatile oil. The preparation method comprises the following steps: volatile oil material liquid is extracted from air-dried and pulverized raw materials by employing a distillation method, and drying treatment is performed on the volatile oil material liquid to obtain the antibacterial volatile oil; and the raw materials are selectedfrom any one or at least two of celery seeds, fructus foeniculi, semen trachyspermi ammi and cumin seeds. According to the preparation method, by taking any one or at least two of the celery seeds, fructus foeniculi, semen trachyspermi ammi and cumin seeds as the raw materials, the volatile oil material liquid is extracted from the pulverized raw materials, and drying treatment is performed on thevolatile oil material liquid to obtain the antibacterial volatile oil; and the antibacterial volatile oil belongs to a natural antibacterial agent, has no side effects of sensitization, inflammationcausing effect, or neurotoxicity and carcinogenesis of chemical antibacterial agents, can be widely used in the field of cosmetics, health-care products and environmental sanitation, and has a good antibacterial effect. The preparation method has the advantages that extraction speed is fast, purity is high, yield is high, the extraction rate reaches 5% or more, and operation is convenient; separation is realized in the extraction process; and the preparation method is safe and reliable, and is an efficient energy-saving extraction and separation method.
