A kind of essential oil composition for antibacterial and insecticidal and preparation method thereof

Abstract

The invention discloses an essential oil composition prepared by performing rectification and compounding processing on the raw materials comprising 4-terpilenol type tea-tree-oil and eucalyptus grandis x e.urophylla essential oil, and provides the formula, a preparation method and the composition content of the essential oil composition; and the composition has antibacterial insecticidal functions. A gas chromatography method is employed to determine the main content. The method is accurate, stable and easy to operate, is adaptable for industrial production demands, and can help to effectively control the quality of the essential oil composition. The essential oil composition has small toxicity, has different levels of inhibition effects on six pathogens comprising staphylococcus aureus, staphylococcus epidermidis, beta hemolytic streptococcus, escherichia coli, pseudomonas aeruginosa and candida albicans which can cause skin infection, and has antibacterial and insecticidal activities. The preparation method is reasonable and stable, short in production period, suitable for industrial production, and good in application prospect.

Description

technical field

[0001] The invention relates to an essential oil composition used for antibacterial and insecticide, which uses tea tree oil and eucalyptus magnum essential oil as raw materials, and is processed through rectification and compounding, and a preparation method thereof. Background technique

[0002] Melaleuca ahernifolia (Melaleuca ahernifolia) is a kind of long green small tree of Melaleuca alternifolia genus. The essential oil extracted from the fresh branches and leaves of Melaleuca alternifolia is commonly known as "tea tree oil". It stimulates to kill fungi and bacteria on the surface of human skin, and has inhibitory effect on some viruses. It is a powerful antibacterial agent and immune activator. It is a rare natural health care medicine material and is widely used in pharmaceuticals. , daily chemical, food and other industries, has been included in the US Food and Drug Administration (FDA) procurement list, included in the European Pharmacopoeia in 200...

Examples

Embodiment 1

[0053] Embodiment 1: Prepare combined essential oil 1, take tea tree oil (4-terpineol type) and different fractions, according to the ratio of tea tree oil: fraction 1: fraction 2: fraction 3 is 6:1:1:1, weighed respectively Add the raw materials into the container and mix evenly to obtain the combined essential oil. Determination of combined essential oils with gas chromatography, the components of the combined essential oils are as shown in the table,
