Embodiment 1

[0047] Embodiment 1: the preparation of grass fruit essential oil

[0048]Weigh 0.5kg each of air-dried and roasted Tsaoko, grind them into coarse powder, and soak them in 3.5L of water for 1h. Extract by steam distillation for 7 hours, collect the essential oil of grass fruit with a volatile oil extractor, calculate the oil yield=(oil yield / weighed grass fruit amount)×100%, the result is that the oil yield of dried grass fruit is 2.0%, roasted The oil yield of hay fruit is 1.3%.

Embodiment 2

[0049] Embodiment 2: the characterization of grass fruit essential oil

[0050] Composition analysis of grass fruit essential oil

[0051] GC / MS method was used to analyze the composition and content of Tsaoko essential oil extracted from dried and roasted Tsaoko. Dilute tsaoko essential oil 10,000 times with n-hexane, and inject 1 μl. GC conditions: use Thermo TR-5MS (30m*0.32mm, 0.25μm) chromatographic column, the initial temperature of the column is 50°C, the temperature is programmed to rise at 6°C / min, and rise to 220°C, and then rise to 250°C at 10°C / min, constant temperature 5min. The inlet temperature is 250°C, the carrier gas is He, the carrier gas flow rate is 2.0ml / min, and the split ratio is 20:1. MS conditions: EI ion source, scan mode fullscan, scan range m / z 50-600amu, ion source temperature 250°C, GC / MS interface temperature 250°C.

[0052] The GC-MS chromatogram of Tsaoguo essential oil sees the attached figure 1 . The results showed that a total of 29 c...

Embodiment 3

[0061] Embodiment 3: the preparation of grass fruit essential oil emulsion

[0062] 1 part of Caoguo essential oil, 3.5 parts of ethanol, 1.5 parts of Tween 80, 4 parts of water, stir evenly, and you get it.

[0063] 1 part of tsaoko essential oil, 2 parts of ethanol, 1.5 parts of alkylphenol polyoxyethylene ether (OP10), 5.5 parts of water, stir evenly, and the product is ready.

[0064] 1 part of tsaoko essential oil, 3.5 parts of ethanol, 0.5 part of alkylphenol polyoxyethylene ether (OP10), 4 parts of water, and stir evenly to obtain the product.

[0065] 1 part of tsaoko essential oil, 3.5 parts of ethanol, 1.5 parts of alkylphenol polyoxyethylene ether (OP10), 4 parts of water, stir evenly, and the product is ready.

[0066] 1 part of tsaoko essential oil, 2.5 parts of ethanol, 1 part of methanol, 1.5 parts of alkylphenol polyoxyethylene ether (OP10), 4 parts of water, stir evenly, and the product is ready.

[0067] Odor evaluation of Caoguo essential oil emulsion: spe...

Abstract

The invention relates to application of amomum tsaoko essential oil and an emulsion thereof as air fresheners and / or air bacteriostats. The amomum tsaoko essential oil and the amomum tsaoko essentialoil emulsion have antibacterial and bacteriostatic effects on the following harmful air microorganisms: escherichia coli, staphylococcus aureus, candida albicans and fungi of penicillium, aspergillusand cladosporium.

Description

technical field [0001] The invention relates to the use of the grass fruit essential oil of plant origin and its emulsion as an air freshener and / or an air bacteriostatic agent, which can be widely used in the prevention and control of indoor air pollution. Background technique [0002] Although there are many types of air fresheners currently on the market, they are basically composed of chemical components such as ether and essence. These substances themselves are air pollutants after chemical decomposition, and the chemical fragrances contained in air fresheners are harmful to The human nervous system can also cause harm and affect the growth and development of children. Many air fresheners made of chemical synthetic preparations only temporarily cover the indoor odor with fragrance, and cannot really improve the quality of the air, nor can they disinfect the microorganisms in the air. [0003] Although many air fresheners are labeled as having a bactericidal effect on t...
