Abstract
The invention provides a preparation method for extracting high-purity lycopene and tomato seed oil from tomatoes, which belongs to the technical field of natural product chemistry. The method comprises the following steps: tomatoes are extracted with supercritical carbon dioxide fluid, washed with 30-80% alcohol solution, dissolved with petroleum ether, and crystallized and recrystallized with excessive absolute alcohol to obtain pure lycopene; and tomato residues are extracted with supercritical carbon dioxide fluid to obtain tomato seed oil. The method provided by the invention has the advantages that the lycopene can be prevented from decomposing at high temperature, active ingredients can be effectively protected, the energy consumption is low, the extracting solvent is non-toxic and is easy to recover, the production cost of lycopene and tomato seed oil can be effectively reduced, and fruit resources are saved.
