Determinação de compostos fenólicos nas cascas de citrus sinensis e mangiferina indica

Abstract

The aim of the present work was to determine and compare the content of phenolic compounds present in the orange and mango peels. Bioactive compounds such as polyphenols present in fruits and vegetables are receiving increasing attention due to their antioxidant potential. The consumption of such antioxidants is linked to health benefits including protection against cardiovascular disease and cancer. Orange and mango are among the most consumed fruits worldwide. These contain different phenolic compounds responsible for several benefits to human health. The peels of these fruits make up about 20% of all fruit and have been discarded, thus becoming a source of pollution. In the present study, the extraction, identification and quantification of phenolic compounds present in orange and mango peel were carried out. For the extraction of these compounds, the soxhlet method with the solvent system EtOH-H2O (4: 1) was used. It was observed that both the orange peel and the mango peel have phenolic compounds, with the mango having a higher content of these in relation to the orange. Among the compounds identified in the skins of our fruits are flavonoids, phenols, quinones, saponins, tannins and triterpenoids.
