Resumen
Syzygium cumini (L.) Skeels, popularly known as jambolão is a large plant. It produces fruits that are known for their expressive antioxidant activity and the presence of natural pigments known as anthocyanins. Antioxidants are substances widely used in the industry, presenting applications in food preservation, production of pharmaceuticals and cosmetics, among others. In this work, from mature fruits, the anthocyanin content, antioxidant activity and fruit characterization were analyzed. Starting from a centroide simplex experimental design, we obtained extracts from which a study was carried out to maximize the antioxidant activity and anthocyanin content. The influence of the response was studied for combinations of three solvents: (x1) ethanol, (x2) acetone and (x3) water. From Statistica Software 7.0, a mathematical model was adjusted to predict the behavior of the response variables, so the optimum extraction point and solvent composition were found. In the extracts, antioxidant activity (AAT) was obtained between 579mg of DPPH per g of lyophilized fruit and 21.9mg g-1. Total monometrical anthocyanins (AMT) were obtained with a maximum value of 488mg 100g-1 and a minimum of 20.8mg 100g-1 of lyophilized fruit.
