Embodiment 1
[0020] Distillation method and cold pressing method to extract the essential oil of fresh torreya arils:
[0021] Using the arils of fresh Torreya grandis cv Meorillii fruits as raw materials, it is the green casks of Torreya grandis cv Meorillii that can be stored for no more than 1 day at room temperature. The essential oil can be extracted from the arils of fresh Torreya grandis cv Meorillii. Double the water to distill in water for 2 to 4 hours, or use a screw cold press to extract the juice. After the obtained juice is centrifuged and precipitated by a centrifuge (the centrifuge speed is 5000 rpm, the time is 20 minutes), the supernatant is taken After distillation, the distillate is separated by an oil-water separator to obtain the essential oil of fresh torreya arils. The oil yield rate of the essential oil of torreya torreya obtained from fresh torreya arils is 0.35-0.45% (w / w, wet basis weight).

Embodiment 2
[0030] The present invention uses the essential oil of torreya as the effective component of the anti-dermatophyte product. In order to confirm the anti-dermatophyte effect of the essential oil of torrenia of the present invention, the present invention has developed an anti-skin effect on the essential oil distilled from the arils of torrenia. The specific methods and results of the study of ringworm activity are as follows:
[0031] 1. Experimental strains
[0032] The in vitro antibacterial activity of Torreya essential oil The strains used in the study are mainly against 6 common pathogenic dermatophytes that cause tinea capitis, tinea corporis and a small number of onychomycosis: Microsporum canis, Microsporum gypsum, Microsporum rust , Trichophyton Ezerau, Trichophyton mentagrophytes, Epidermophyton flocculent.
[0033] 2. Experimental method
[0034] The minimum inhibitory concentration MIC test is slightly modified in accordance with clinical and laboratory standard documents...
Embodiment 3
[0041]
[0042] Preparation method: Add one ingredient at a time to the appropriate volume of redistilled water under stirring until it is completely decomposed, and then add another ingredient. After adding distilled water to 2ml, the solution was filtered on a sterile filter, filled into bottles and separated according to the appropriate dose.
