Abstract
The present disclosure relates to the technical field of nut-derived fruit oil preparation, in particular to a method for extracting palmitoleic acid from Macadamia integrifolia and use thereof. In the method for extracting palmitoleic acid from Macadamia integrifolia, a fruit oil of the Macadamia integrifolia is purified by vacuum distillation, and an antioxidant is added during the vacuum distillation. A preparation method of the antioxidant includes the following steps: extracting a pulverized Macadamia integrifolia green peel using ethanol by heat reflux to obtain a green peel extract; extracting the green peel extract using petroleum ether, and then using ethyl acetate; collecting an ethyl acetate layer to obtain the antioxidant. The method can avoid easy oxidization and deterioration of oil during extracting and enriching the palmitoleic acid, and can enrich the palmitoleic acid in the fruit oil of the Macadamia integrifolia by not less than 3 times.
