H, separator pressure is 6-7MPa, and temperature is 40-45 DEG C, extracts 1.5-2h, releases extract from separator bottom, after standing,
Thyme oil is obtained through oil-water separation.
As preferably, step is as follows:
(1) agent of carrying accounting for Herba thymi vulgaris weight 0.4% is sprayed in Herba thymi vulgaris, then Herba thymi vulgaris is added in extraction kettle, face with super
Boundary's CO 2 fluid carries out continuous cycling extraction, controls extraction kettle temperature 35 DEG C, extracts pressure 20MPa, and flow velocity is 18kg/h,
Extraction time 2h；Described carry agent and be mixed by each component of following mass fraction: ethanol 62 parts, 4 parts of acetone, ether 1.5
Part；
(2) CO 2 fluid after extraction being entered separator to separate, the flow of CO 2 fluid is 18kg/h, point
Being 6.5MPa from device pressure, temperature is 42 DEG C, extracts 1.5h, releases extract from separator bottom, after standing, through oil-water separation
Obtain thyme oil.
It is high that the method using the present invention extracts the thyme oil purity obtained, and fragrance can be effectively retained.
Detailed description of the invention
Below example facilitates a better understanding of the present invention, but does not limit the present invention.Experiment in following embodiment
