Embodiment 1

[0048] (1) In June, take the stems and leaves of Pelargonium geranium, wash and dry them, then cut the stems of geranium geranium into sections, and cut the leaves of geranium geranium into an area of ​​1-4cm 2 small pieces of

[0049] (2) Add the segmented geranium geranium stems and small pieces of geranium geranium leaves in (1) into water, the solid-liquid weight ratio of geranium geranium stems and geranium geranium leaves to water is 1:3, smash into a paste;

[0050] (3) Adjust the temperature of the pasty material to 50°C, add cellulase to the material in an amount of 0.3% of the total weight of the pasty material, enzymatically hydrolyze for 30 minutes, and inactivate the enzyme at 95°C for 9 minutes;

[0051] (4) Add yeast powder to the enzymolysis solution in (3), the amount added is 0.3% of the weight of the enzymolysis solution; keep at 40°C for 20 minutes;

[0052] (5) Keep the raw materials in (4) at 100°C for 15 minutes;

[0053] (6) Place the material in (5)...

Embodiment 2

[0063] On the basis of Example 1, continue to step (10), add activated carbon to the geranium oil in (9), heat to 55° C., stir at a speed of 30 r / min, and filter to obtain geranium oil.

Embodiment 3

[0065] (1) In May, take the stems and leaves of Pelargonium geranium, wash and dry them, then cut the stems of geranium geranium into sections, and cut the leaves of geranium geranium into an area of ​​1-4cm 2 small pieces of

[0066] (2) Add the segmented geranium geranium stems and small pieces of geranium geranium leaves in (1) into water, the solid-to-liquid weight ratio of geranium geranium stems and geranium leaves to water is 1:2, smash into a paste;

Abstract

The invention belongs to the technical field of plant spice extraction, and particularly relates to an extraction method of geranium oil. The method comprises the following steps: (1) selecting stemsand leaves of Pelargonium roseum Ait. as raw materials; (2) smashing the stems and leaves into paste; (3) performing enzymolysis; (4) adding yeast powder for treatment; (5) performing high temperaturetreatment; (6) performing emulsification and homogenization; (7) performing ultrasonic treatment; (8) performing concentration; and (9) performing distillation. By adopting the method for extractingthe geranium oil, the extraction rate of the geranium oil is obviously increased, and the method adopts an enzymolysis mode with mild reaction conditions, thereby overcoming the environmental problemscaused by the traditional organic solvent extraction method and avoiding complicated procedures caused by subsequent recovery or treatment of an organic solvent.

Description

technical field [0001] The invention belongs to the technical field of extracting plant spices, and in particular relates to a method for extracting geranium oil. Background technique [0002] Geranium oil is one of the most important essential oils in the global fragrance industry. It has a honey-sweet and long-lasting aroma. It is often used as a spice to prepare rose essence, and is also commonly used in roses, hyacinths, carnations, lilacs, tuberoses, and lilies of the valley and violet and other flavor formulations. In recent years, it has been found that geranium oil has a stable moderate curative effect on animal tumors, and has an obvious killing effect on cancer cells in vitro. Its oral capsules and suppositories have good curative effect in clinical treatment of cervical cancer. [0003] Geranium oil is generally obtained by steam distillation, which mainly includes four steps, namely drying the leaves, putting them in a retort, heating, and time. Bhaskaruni R e...
