Abstract

The invention discloses a method for extracting turmeric oil. The problems in the prior art that the extraction rate is low, the refined oil quality is low, the production is complicated and production cost is high are solved. The method for extracting turmeric oil disclosed by the invention comprises the following steps: grinding medicinal turmeric, performing enzymolysis, adding water for performing ultrasonic extraction, filtering, standing, performing oil-water layering, and taking the oil phase, so as to obtain the product. According to the method disclosed by the invention, the extraction rate of the oil is high, the obtained oil has excellent quality, the process is simple, and the production cost is low.

Description

technical field [0001] The invention belongs to the technical field of medicine extraction, and in particular relates to a method for extracting turmeric essential oil. Background technique [0002] It is the dry rhizome of Curcuma longa L., a ginger plant. Excavate when the stems and leaves wither in winter, wash, boil or steam until thoroughly, dry in the sun, and remove fibrous roots. Turmeric is pungent, bitter, and warm in nature; it returns to the spleen and liver channels. It has the effects of dispelling blood and promoting qi, dredging menstruation and relieving pain, and is used for chest and hypochondria tingling pain, amenorrhea, lump in the abdomen, rheumatism shoulder and arm pain, tumbling and swelling. Turmeric medicinal material is rich in various chemical constituents, including volatile oil constituents. Modern pharmacological studies have shown that turmeric has various functions such as lowering blood fat, anti-tumor, anti-inflammation, anti-pathogeni...
