The aim of this study was to determine the content of bioactive compounds and antioxidant activity present in three fruit species from the Brazilian Cerrado: carnauba (Copernicia prunifera (Mill.) H.E. Moore), murici (Byrsonima crassifolia L. Rich)and oiti (Licania tomentosa (Benth) Fritsch). Among analyzed fruits, oiti showed the highest total phenolic content (1236.42 ± 34.06 mg GAE 100 g-1) followed by murici (468.90 ± 27.30 mg GAE 100 g-1) and carnauba (314.44 ± 9.50 mg GAE 100 g-1). Regarding the antioxidant activity, murici showed 4350.31 ± 1.85 µmol TEAC.100 g-1 and oiti showed 14721.69 ± 0.85 µmol TEAC.100 g-1. In addition, high content of anthocyanins was verified in carnauba (9.35 ± 0.00 mg-cy-3-glu.100 g-1), as well as carotenoids (20.0 ± 1.23 mg-ß-carot.100 g-1) and vitamin C (58.60 ± 1.32 mg.100 g-1) in murici. In conclusion, data obtained add valuable information to the current knowledge on the nutritional and functional features of fruits from the Brazilian Cerrado that have been scarcely explored, such as those analyzed, which showed high content of bioactive compounds and antioxidant activity.
Brazil has the largest biodiversity of any country in the world, which includes a large number of fruit species. Cerrado, a Brazilian biome that has a large number of underexploited native and exotic fruit species, is of potential interest to the agroindustry and a possible future source of income for the local population. This paper presents the centesimal composition, phenolic contents, anthocyanin, flavonoids, and antioxidant activity of Genipa americana L. fruit. The results indicated the following composition: moisture (75.00%), lipids (1.60%), proteins (0.67%), carbohydrates (20.50%), and ash (2.20%). The Genipa americana fruit contained considerable amounts of phenolic compounds (857.10 mgGAE.100 -1 g) and flavonoids (728.00 mg.100 -1 g), which contribute to its high antioxidant activity. This study highlights the potential of this fruit as an important source of both nutritional and bioactive compounds available in the native Brazilian flora.
In the present study, the effects of cryolipolysis on one and multiple body areas, assessing body composition, lipid profile and peroxidation and inflammatory markers were investigated. Twenty-five women aged between 20 and 59 years were randomly assigned to three groups: (1) control, (2) cryolipolysis on the abdomen and (3) cryolipolysis on the abdomen + flanks. Anthropometric measurements, bioimpedance and ultrasound were performed, as well serum lipid profile, lipid peroxidation markers (malondialdehyde and myeloperoxidase) and inflammatory markers (C-reactive protein and Interleukin-1β) were determined. In addition, food consumption and physical activity level were evaluated. Data were obtained at 0, 10 and 30 days (t0, t10 and t30) after cryolipolysis. Cryolipolysis did not change anthropometric measurements, body composition or lipid profile. Interestingly, the abdomen + flanks group had significantly increased plasma myeloperoxidase activity at t0, t10 and t30, and increased malondialdehyde levels at t0 and t10 when compared to the other groups. Furthermore, there were no differences between macronutrient intake and total energy value, physical activity level, malondialdehyde and interleukin-1β at t30. Cryolipolysis did not change body composition, lipid profile or inflammatory markers investigated. On the other hand, when used on the abdomen and flanks, it produced an increase in lipid peroxidation markers, malondialdehyde and myeloperoxidase.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
