Abstract

The invention discloses a method for extracting curcuma oil and curcumine from rhizoma curcumae longae. The method comprises the following steps: grinding the rhizoma curcumae longae into rhizoma curcumae longae powder of 20-40 meshes or rhizoma curcumae longae slices, taking subcritical fluid R134a as an extracting agent, and extracting the rhizoma curcumae longae powder or the rhizoma curcumae longae slices by ultrasonic enhancement to obtain an extracting solution and rhizoma curcumae longae residues; analyzing, separating and desolventizing the extracting solution, and refining by adopting a supercritical CO2 method to prepare the curcuma oil; and taking the rhizoma curcumae longae residues as raw materials and ethanol as an extracting agent, extracting the rhizoma curcumae longae residues by ultrasonic enhancement, concentrating the extracting solution, filtering, decreaming, feeding into a supercritical CO2 fluid crystallizing device for crystallizing, and filtering crystals to obtain the curcumine with the purity of more than 95%. According to the method, the ultrasonic technology, the subcritical R134a fluid technology and the supercritical CO2 fluid technology are combined, the extraction operation is carried out under the synergistic effect of the three technologies, the curcuma oil and the curcumine as the two main effective ingredients of the rhizoma curcumae longae can be continuously and sequentially extracted in the same device, and the extraction rate is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of extraction, and in particular relates to a method for extracting turmeric oil and curcumin from turmeric. Background technique [0002] Turmeric is the rhizome of turmeric, a plant in the ginger family. The main chemical components of turmeric are curcuminoids and volatile oils. In addition, it also contains sugars, sterols and trace elements. Among them, curcumin is a mixture of three components such as alcohol-soluble diphenylheptane compound curcumin, demethoxycurcumin and bisdemethoxycurcumin, and is an ideal natural pigment. It is also the main component of turmeric to exert its pharmacological effects. The main components of turmeric volatile oil are curcumene, curcumone and dehydroturmerone, etc., which have good antibacterial, antitumor and anti-inflammatory effects, so they are widely used in food, medicine and chemical industries. Studies have shown that curcumin has multiple pharmacological e...
