“…Tucum-do-cerrado ( Bactris setosa Mart. ), a Brazilian savanna fruit, has a high content of different phytochemical compounds such as cyanidin-derivatives, epicatechin, catechin, piceatannol, quercetin, and all- trans -lutein, mainly found in the peel [ 25 , 27 ] and a high antioxidant potential in vitro and in vivo [ 28 , 29 , 30 ]; however, many other potential biological effects still need to be investigated. Therefore, we hypothesized that the dietary consumption of tucum-do-cerrado ( Bactris setosa Mart.…”

Aging may be related to oxidative damage accumulation and a low-grade inflammation, both responses are modulated by iron and phytochemicals. This study investigated the effect of tucum-do-cerrado (Bactris setosa Mart.) consumption on the expression of sirtuins (SIRT 1 and 3) and senescence marker protein-30 (SMP30), and on the redox and inflammatory responses, in adult rats supplemented or not with dietary iron. Male Wistar rats were treated for 12 weeks with: control diet (CT); iron enriched-diet (+Fe); control diet + 15% tucum-do-cerrado (Tuc); or iron enriched-diet + 15% tucum-do-cerrado (Tuc + Fe). Iron supplementation (+Fe) increased liver, spleen and intestine iron levels, transferrin saturation, serum iron, serum TNF-α and IL-6 levels, hepatic carbonyl content and and superoxide dismutase (SOD) activity, hepatic Nrf2 protein and Nqo1 mRNA levels and decreased the renal Sirt1 mRNA levels in relation to CT group. Tucum-do-cerrado consumption (Tuc) increased hepatic SOD activity, Nrf2 and SIRT1 mRNA and protein contents, and Nqo1 mRNA levels, while it decreased the renal SOD activity compared with the CT diet. The consumption of tucum-do-cerrado associated with the iron-enriched diet (Tuc + Fe) increased the iron levels in tissues and serum transferrin saturation, compared to the CT diet, while promoting a decrease in hepatic carbonyl and renal malondialdehyde levels, marginally reducing serum IL-6 levels, and increasing hepatic SIRT1 protein content, renal Sirt1 and hepatic Nrf2 mRNA levels, compared to the +Fe group. None of the treatments altered Smp30 mRNA levels. The results suggest that tucum-do-cerrado consumption might promote an anti-aging effect by increasing SIRT1 expression, which may enhance Nrf2 mRNA and protein levels and its downstream pathway, which in turn decrease oxidative damage to proteins and the levels of inflammatory cytokines (IL-6 and TNF-α), induced by iron excess.

Summary In this study, the antioxidant activities of blueberry anthocyanin extracts from ten blueberry varieties were evaluated based on the methods of scavenging activities for DPPH radicals, ABTS radicals, hydroxyl radicals and ferric reducing antioxidant power (FRAP) assay. Among the ten blueberry varieties, Polaris had the highest antioxidant abilities and the largest amounts of anthocyanins identified by HPLC‐MS. The protective effects of anthocyanin extracts from Polaris (AEP) against acrylamide (AA)‐induced toxicity in HepG2 cell models were also evaluated due to the neurotoxic, genotoxic and potentially carcinogenic effects of AA. The protective effects of AEP on the damage of HepG2 cells were explored from the aspects of cell viability, T‐SOD and CAT activity and MDA level. The AEP (5, 10, 20 μg mL−1) could significantly increase cell viability (P < 0.01) and inhibit AA‐induced cytotoxicity. Polaris also markedly promoted the activity of SOD, CAT and inhibited MDA level. The results showed that AEP had strong antioxidant activities, presenting high protective effects against AA‐induced cell damage in HepG2 cell models.

Brazil has high diversity of native fruits with high nutritional and biochemical value. Bactris setosa Mart. (tucum-do-Pantanal) stands out by its oil-rich almond. This study aimed to determine the physicochemical characteristics of tucum-do-Pantanal almond and its by-products: press cake and crude oil. The almond of tucum-do-Pantanal had total weight of 0.81g, lager diameter 10.87mm, small diameter 8.21mm, height 12.50, weight of almond 0.38g, weight of endocarp 0.25g. In relation to the chemical analysis, the cake had higher ash, protein and carbohydrate contents than the almond. On the other hand, the content of moisture, lipids and calories were higher in the almond. The press cake showed 636.80 g kg-1 of total fiber. The fatty acids that predominated in tucum-do-Pantanal oil were lauric (58.48), myristic (12.59) and oleic (10.15%) acids. The oil of tucum-do-Pantanal had an acid index of 3.01 KOH / g, peroxide index of 4.84 meq / kg, saponification index of 140.91 mg KOH / oil g, iodine index of 3.72 gI2 / 100 g, refractive index of 1.46, density of 0.92 g / mL, water content of 493.11 ppm and oxidation stability of 32.01 h. The results suggest that tucum-do-Pantanal almond as an important source of oil, calories and fibers, with potential use in the food industry.
