Abstract

The invention discloses an extraction method of natural components in plants, and belongs to the technical fields of bio-energy and resource recycling. Seeds, flower and fruits of oil-containing cropsare used as raw materials, after conventional treatment is conducted, extraction is conducted by means of an extraction agent to obtain mixed oil, a phase separation switch is added into the mixed oil, the extraction agent is separated out, and the natural components are extracted. According to the extraction method of the natural components in the plants, the extraction technology is simple andeasy to implement, and the extraction method of the natural components in the plants aims to solve the problems of low yields of natural components in plants, and high energy consumption and a low recovery rate of extraction agent recovery in a production process.

Description

technical field [0001] The invention discloses a method for extracting natural components in plants, which belongs to the technical field of bioenergy and resource reuse. Background technique [0002] The natural ingredients contained in plants have very good application prospects in the fields of medicine, beauty, health care and industry due to their high safety, high added value and diverse functions. At present, the techniques for extracting natural components from plants include traditional solvent method and new supercritical extraction method, enzymatic separation method, microwave method, ultrasonic method and ultra-high pressure extraction method, etc. [0003] The supercritical extraction method has the advantages of high purity of the obtained product, simple operation and no solvent residue, but its equipment is expensive and the extraction conditions are harsh; the enzymatic separation method has the advantages of mild separation conditions and can ensure the bi...
