A method of extracting Clove Oil Dischem, comprising the following steps:
(1) Mechanical activation: drying lilac buds to make the water content 5%, taking 1000 g of sun-dried lilac buds and adding them to a vertical stirring ball mill, and mechanically activating them for 3 minutes at a rotational speed of 500 r/min to obtain lilac powder;
(2) Soaking: add the above clove powder into the distillation tank, then add 0.5kg of cellulase and add water, pressurize with a slate so that the water just soaks the clove powder, and soak at room temperature for 5 hours to obtain an extract;
(3) Distillation: the extraction liquid is heated by introducing steam from the bottom of the distillation tank, and the extraction liquid is boiled and extracted for 2 hours to obtain mixed steam;
(4) Condensation: the mixed steam obtained above is condensed by a condenser, and an oil-water mixture is obtained after condensation;
(5) Oil-water separation: the oil-water mixture obtained by condensation is separated from oil and water by an oil-water separator to obtain clove crude oil and water;
(6) Extraction: The obtained crude clove oil is extracted through an extraction tank, and after layering, the lower layer is separated to be Clove Oil Dischem.
The present embodiment obtains 218g of Clove Oil Dischem, and the obtained Clove Oil Dischem has a purity of 98.66%.
Take 100g of clove powder, put it in a 2000mL round-bottom flask, and add 1000mL of water. Set the volatile oil extraction device to reflux extraction for 4 hours, and collect the volatile oil. Add 5 mL of petroleum fan to the collected volatile oil and shake slightly. After static, the oil-water layer was removed, and the oil fan was evaporated at 40°C to obtain pure Clove Oil Dischem, the yield of which was 0.67%.
