Embodiment 1

[0040] (1) preparation of yew essential oil:

[0041] Pick 100 g of fresh yew branches and leaves that grow normally, clean them with distilled water, dry them under reduced pressure, crush them through a 100-mesh sieve to obtain a coarse powder, add the coarse powder into a dilute hydrochloric acid solution with twice the volume concentration of 0.1%, and soak for 3 hours. The temperature is 28°C, and the filter residue is obtained by vacuum filtration. The filter residue is added to three times the volume of distilled water and soaked for 3 hours. The soaking temperature is 28°C. After pressing and drying to a water content of 4%, the yew powder is obtained by air-flow ultrafine grinding until the particle size is less than 80 μm; the yew powder is added to 10 times the volume of absolute ethanol, and placed in an atmospheric pressure microwave-assisted synthesis reactor In the process, under the power condition of 400W, the microwave radiation was irradiated for 5.0min to o...

Embodiment 2

[0046] (1) preparation of yew essential oil:

[0047] Pick 100 g of fresh yew branches and leaves that grow normally, clean them with distilled water, dry them under reduced pressure, and crush them through a 100-mesh sieve to obtain a coarse powder. The temperature is 30°C, and the filter residue is obtained by vacuum filtration. The filter residue is added to three times the volume of distilled water and soaked for 2 hours. The soaking temperature is 30°C. After pressing and drying to a water content of 3%, the yew powder is obtained by air-flow ultrafine pulverization until the particle size is less than 80 μm; the yew powder is added to 13 times the volume of absolute ethanol, and placed in an atmospheric pressure microwave-assisted synthesis reactor In the process, under the power condition of 350W, the microwave radiation was irradiated for 5.0min to obtain the yew liquid; the yew liquid was put into the extraction kettle for supercritical CO 2 Extraction, the extractio...

Embodiment 3

[0052] (1) preparation of yew essential oil:

[0053] Pick 100 g of fresh yew branches and leaves that grow normally, clean them with distilled water, dry them under reduced pressure, crush them through a 100-mesh sieve to obtain a coarse powder, add the coarse powder to twice the volume concentration of 0.1% dilute hydrochloric acid solution and soak for 4 hours, soak The temperature is 25°C, and the filter residue is obtained by vacuum filtration. The filter residue is added to three times the volume of distilled water and soaked for 4 hours. The soaking temperature is 25°C. After pressing and drying to a water content of 5%, the yew powder is obtained by air-flow ultrafine grinding until the particle size is less than 80 μm; the yew powder is added to 9 times the volume of absolute ethanol, and placed in an atmospheric pressure microwave-assisted synthesis reactor In the process, under the power condition of 450W, the microwave radiation was irradiated for 5.0min to obtain ...

Abstract

The invention discloses antibacterial taxus chinensis compound essential oil as well as a preparation method and application thereof. According to the preparation method, taxus chinensis essential oilis extracted by virtue of an extraction method with combination of microwave radiation and supercritical CO2 extraction, so that effective components beneficial to a human body in taxus chinensis arepreserved, biological macromolecules are degraded, and the dissolution rate is increased; the taxus chinensis compound essential oil prepared from taxus chinensis essential oil, chamomile essential oil, lemon essential oil, jasmine essential oil, tea tree essential oil and basic oil has relatively strong sterilization and antibacterial effects and has relatively strong sterilization effects to escherichia coli, staphylococcus, pseudomonas aeruginosa and candida albicans; and by applying the taxus chinensis compound essential oil to the technical field of skincare, a prepared emulsion is safe,non-toxic, non-irritant, capable of clearing free radicals, slowing the cell aging of an organism and effectively resisting external radiation and injure caused by ultraviolet ray to the skin and hasgood film-forming property.

Description

technical field [0001] The invention relates to the technical field of yew processing, in particular to yew compound essential oil with antibacterial effect and its preparation method and application. Background technique [0002] In recent years, essential oil-added skin care products have begun to enter people's field of vision, and gradually become the new darling of women's skin care in the new era. The so-called essential oil-added skin care products refer to skin care products that use pure natural aromatic plant essential oils as the main function and aromatic additives, without using artificial fragrances, pigments, preservatives and other chemical ingredients. Because it has the characteristics of natural plant essential oils, easy penetration and absorption, and powerful efficacy, it also abandons the defects of plant essential oils that are too professional and complicated to operate, and at the same time has the advantages of convenient use and simple operation o...
