[0028] Example one
[0029] The preparation of yew essential oil powder: pick the whole and disease-free branches and leaves of yew more than ten years old, clean the surface impurities with clean water, then rinse with acid detergent, rinse with clean water for 10 minutes, and spray with distilled water for 10 minutes. Cut into small sections, soak in 0.1mol / L acetic acid solution at 33℃ for 12h, remove it and soak it in distilled water at room temperature for 15h, remove it and rinse with distilled water for 10min, and dry until the water content is below 8%. Superfinely pulverized to a particle size of less than 80μm to obtain yew powder; put the yew powder into the extraction kettle for supercritical CO 2 Extraction, with absolute ethanol as entrainer, set CO 2 The flow rate is 16L / h. After the start of extraction, anhydrous ethanol is passed at a rate of 2.00mL / min. The extraction temperature is 50℃, the extraction pressure is 22MPa~23MPa, the extraction time is 1.6h, the sep...
