Acrocomia aculeata fruits are rich in monounsaturated fatty acid, β-carotene, tocopherol, and other antioxidant compounds. The aim of our study was to investigate and compare the protective effects of A. aculeata pulp oil and microencapsulated pulp oil on brain oxidative damage induced by chronic restraint stress (CRS) in rats (cortex, hippocampus, and striatum). Thirty-six Wistar rats were divided into six treatment groups: C, P, and M groups received 1 μL/g of body weight of distilled water, pulp oil, and pulp oil microcapsules by daily gavage, respectively. The SC, SP, and SM groups received 1 μL/g of body weight of distilled water, pulp oil, and pulp oil microcapsules by daily gavage, respectively, and were then subjected to uninterrupted 6 h of CRS. After 21 days of testing, the rats were euthanized and the brain tissue of the groups was removed for evaluation for oxidative damage markers and antioxidant enzymes. Endpoints of oxidative stress (OS) markers (lipid peroxidation, protein carbonylation, and reduced glutathione [GSH]) and antioxidant enzymes (superoxide dismutase and catalase) were evaluated. By imposing chronic stress on rats, pulp oil and microcapsules of pulp oil induced positive antioxidant responses, mainly by increasing the GSH content, increasing the ability of neural tissues to deal with inherent OS, thus protecting against neurodegenerative diseases. The administration of A. aculeata pulp oil and microencapsulated pulp oil made the reversal of the oxidant parameters, which may protect the brain tissue of rats altered by CRS.
