Embodiment Construction

[0011] The technical solution of the present invention will be described in detail below.

[0012] A method for extracting eucalyptus essential oil, comprising the steps of:

[0013] (1) Remove impurities from eucalyptus and dry the eucalyptus flakes until the moisture content does not exceed 10%, and crush them to 40 mesh for later use.

[0014] (2) Use LED light to irradiate eucalyptus grains: specifically, the illumination time of 15-25min is adopted, the illumination intensity is 15-20lx, and the color temperature of illumination is 5500-6000K; as an embodiment of the present invention, the LED light irradiation time 20min, the light intensity is 20lx, and the light color temperature is 5500K. Certainly, as another embodiment of the present invention, the LED light irradiation time is 25 minutes, the light intensity is 15lx, and the light color temperature is 6000K; or, the LED light light irradiation time is 15min, the light intensity is 20lx, and the light color tempera...

Abstract

The invention discloses an extraction method of eucalyptus essential oil. The extraction method comprises the following steps: (1) removing impurities from eucalyptus, drying to obtain eucalyptus slices with the water content of not more than 10%, and pulverizing to 40 meshes for later use; (2) irradiating the eucalyptus particles by LED (light-emitting diode) light, wherein the light irradiation time is 15-25 minutes, the intensity of illumination is 15-20lx, and the color temperature is 5500-6000K; (3) adding 3 times by weight of anhydrous ethanol, and standing at 20 DEG C for 1 hour to obtain a mixed solution; (4) putting the mixed solution treated by the step (3) into a microwave extraction instrument, and carrying out microwave treatment under the microwave power condition of 400W for 10 minutes; and (5) carrying out vapor extraction, refrigerating the collected crude product in a 5-DEG C refrigerator for 2 hours, and finally, carrying out centrifugal operation to implement oil-water separation.

Description

technical field [0001] The invention relates to the technical field of extracting essential oil from plants, in particular to a method for extracting eucalyptus essential oil. Background technique [0002] With the continuous development of economy and society and the continuous improvement of people's living standards, the demand for plant essential oils is increasing. Essential oils are a general term for a class of oily liquids that are volatile, have a strong fragrance and smell, and can be distilled with water vapor. Essential oils have active ingredients and have a wide range of applications, such as eliminating phlegm and relieving cough, dispelling wind and invigorating the stomach, repelling insects, anti-wrinkle maintenance, etc. The essence of the most popular water therapy (SPA) is natural plant essential oils. For the extraction of essential oils, the current commonly used methods are steam distillation and solvent extraction, but there are disadvantages such as...
