Abstract: The invention relates to a method for obtaining membrane vesicles enriched in membrane transport proteins of plant origin, for cosmetic or therapeutic use, which can contain other substances, such as natural bioactive compounds. Preferably, said vesicles are obtained from plants of the Brassicaceae (cruciferae) family. In addition, the invention relates to a method for increasing these proteins of plant origin.

Abstract: The present invention is referred to a method of production of plant powder for use in food and plant protection, preferentially obtained from plant crops of the Brassicaceae family (Crucifers). Also, the present invention is referred to a plant powder obtained by the procedure of the invention and the use of the plant-derived powder in food and plant protection as herbicide and insecticide. Moreover, this invention is referred to a foodstuff that incorporates the plant powder of the invention in edible forms either in solids, beverages, food supplements or additives, as well as a plant pest control product (herbicide and insecticide) that incorporates the plant powder of the invention.

Abstract: The reaction occurs in a medium buffered with phosphate in an aqueous medium, at neutral pH and at room temperature. Hence, the reaction medium consists of: tyrosol, as precursor; (commercial) mushroom tyrosinase to catalyze the process and vitamin C in excess. Reaction starts after initial shaking. The reaction stops when the concentration of the initial tyrosol is exhausted. In order for the reaction to continue, it will suffice to add more tyrosol (always ensuring that the vitamin C/tyrosol ratio is more than 1). Once the desired concentration of hydroxytyrosol is obtained, it is filtered. The enzyme with molecular weight over twice the size of the pore is retained in the filter and can be used once again. This first extract, which is very enriched in antioxidant hydroxytyrosol with a high antioxidant capacity (in the present case, in combination with vitamin C), can already be used as a food additive.
