Araçá (Psidium cattleianum Sabine): compostos bioativos, atividade antioxidante e inibição da lipase pancreática

“Araca” has been reported with different biological activities such as antioxidant, antiproliferative and antimicrobial as well as inhibitors of digestive enzymes. The digestive pancreatic lipase enzyme plays a fundamental role in lipid metabolism, and its inhibition has been studied as a target for obesity treatment. This study quantified the bioactive compounds present in different parts of “araca” fruit and evaluated their antioxidant activity and lipase inhibition properties. Three samples were analyzed for total anthocyanins, total phenolic content, antioxidant activity and pancreatic lipase inhibition. Anthocyanins were reported only in pulp-peel of red “araca” sample. Phenolic compounds concentration was higher in pulp-peel than in seeds for all samples. The antioxidant activity followed the same trend. A positive correlation was observed between total phenolic content and both antioxidant activity and lipase inhibition. Lipase inhibition activity was higher for pulp-peel compared to the seeds. Overall, the results showed that “araca” fruit extracts could be beneficial for the treatment of obesity
