The present invention relates to a process for the partial and differential extraction that leads to obtaining extracts with appreciable amounts of antioxidants from fruits of palm trees of the genus Euterpe. The process comprises the steps of collecting the fruit, solid-liquid extraction (pulping 1) of the antioxidant compounds, softening and/or maceration of pulp and solid-liquid extraction (pulping 2 and/or 3) to obtain a standardized juice comprising both hydrophilic and lipophilic antioxidants, and an oily fraction. The process of the present invention also extends to a partial purification of the crude aqueous extract produced by the technique of adsorption on macroporous resins, resulting in higher purity extract of antioxidants. The extract or powder obtained after drying can be used in the food industry, cosmetics, pharmaceutical and herbal areas due to the physiological properties thereof
