H, separator pressure is that 6-7MPa, temperature is 35-40 DEG C, extracts 1.5-2.5h, releases extract, standing from separator bottom
Afterwards, through oil-water separation, laurin oil is obtained.
Preferably, step is as follows：
（1）The carrying agent for accounting for Laurel flower weight 0.5% is sprayed in Laurel flower, then Laurel flower is added in extraction kettle,
Continuous cycling extraction being carried out with supercritical carbon dioxide fluid, controlling 38 DEG C of extraction kettle temperature, extract pressure 20MPa, flow velocity is
17kg/h, extraction time 3h；The carrying agent is grouped into by each group of following mass fraction：68 parts of ethanol, 0.2 part of ether, stone
0.5 part of oily ether；
（2）CO 2 fluid after extraction is entered separator to carry out separating, and the flow of CO 2 fluid is 12kg/h, point
Being that 6.5MPa, temperature is 38 DEG C from device pressure, 2h is extracted, extract is released from separator bottom, after standing, obtain through oil-water separation
To laurin oil.
The laurin oil purity height for obtaining is extracted using the method for the present invention, fragrance can be effectively retained.
