“…These values demonstrated that jatobá had a high concentration of phenols, associated with its antioxidant activity potential. Peres et al (2013) reported a total phenol level in the ethyl acetate extract of jatobá fruit pulp of 18 ± 1.54 μg GAE/mg of extract, finding a higher concentration of pulp phenolics in jatobá compared to other fruits of the Cerrado, such as jabuticaba (Myrciaria cauliflora) (7.92 ± 0.56 μg GAE/mg), but showing better extraction of phenolics from the fruit peel. Rocha et al (2013) found higher values of GAE in ethanol extracts compared to aqueous (34.1 and 25.19 mg GAE/100 g, respectively).…”

Dxygen metabolism in cells causes the production of free radicals, which produce damage, including changes in cell structure and function. Antioxidants are substances that, at low concentrations, slow down or prevent oxidation. Fruits and vegetables contribute to the dietary supply of these compounds. The flora of the Cerrado in Brazil has shown to have high levels of bioactive compounds. This study aimed to characterize the antioxidant activity of the pulp of jatobá-do-cerrado in vitro and in vivo. In vitro antioxidant activity of the aqueous, ethanol and aqueous acetone extracts was evaluated by the DPPH method. We determined total phenols by the Folin-Ciocalteu assay and tannins by the Folin-Denis method. In vivo antioxidant potential of the aqueous acetone extract was evaluated by the TBARS technique. The aqueous acetone extract had the highest antioxidant capacity, followed by the aqueous and ethanol extracts. The same pattern occurred in the extraction of phenols and in the extraction of tannins. In vivo administration of the aqueous acetone extract inhibited lipid peroxidation compared to the control group. The inhibition of peroxidation has increased by elevating the dosage concentration of the extracts, demonstrating a significant antioxidant potential in vivo as well as in vitro.

“…A atividade em baixas concentrações é uma das vantagens do uso de herbicida natural em relação ao sintético, a qual foi evidenciada pelos resultados de Shao et al (2013) com o uso de harmalina. O extrato etanólico dos frutos de Byrsonima intermedia, outra espécie da família Malpighiaceae encontrada no Cerrado, apresentou efeitos itotóxicos sobre as espécies alvo tomate e cebola, sendo a atividade atribuída ao elevado conteúdo de compostos fenólicos (PERES et al, 2013).…”

“…Esta se caracteriza pela interação positiva ou negativa de espécies vegetais ou microorganismos sobre o crescimento de sistemas biológicos (PINTO, 2002), a qual é atribuída aos aleloquímicos, isto é, compostos biossintetizados via metabolismo secundário e liberados (volatilização, exsudação radicular, lixiviação ou decomposição de resíduos) no ambiente, a partir de tecido vivo ou morto de qualquer parte do vegetal (SOUZA FILHO;ALVES, 2002). Estudos de alelopatia têm avaliado a ação de diversos extratos e metabólitos secundários bioativos, extraídos de material vegetal, com resultados promissores para o controle de plantas daninhas (CÂNDIDO et al, 2013;IMATOMI et al, 2013b;GRISI et al, 2015). O controle dessas espécies, mediante a aplicação de aleloquímicos, pode ter uma importância estratégica pela sua atuação seletiva e pelo baixo poder residual (RIZVI et al, 1999).…”

Fitotoxicidade de extratos etanólicos de frutos e folhas de Banisteriopsis oxyclada (A. Juss.) B. Gates sobre o crescimento de plantas daninhas

http://dx.doi.org/10.5007/2175-7925.2016v29n1p1O objetivo deste estudo foi avaliar o efeito do extrato etanólico de folhas e frutos de Banisteriopsis oxyclada sobre o crescimento de plântulas de amendoim-bravo e capim-arroz. O extrato bruto etanólico foi preparado na proporção de 100 g de material vegetal seco para 500 mL de etanol. A partir deste, os extratos foram solubilizados em solução tampão e dimetil sulfóxido (DMSO), nas concentrações 10,0; 7,5; 5,0 e 2,5 mg/mL. Foi avaliado o crescimento do sistema radicular, da parte aérea e das células do metaxilema radicular das plântulas. Os extratos etanólicos de folhas e frutos de B. oxyclada exerceram atividade inibitória no crescimento radicular de plântulas de capim-arroz e amendoim-bravo, com efeito dependente da concentração. Foi observada redução no crescimento da parte aérea apenas nas plântulas de amendoim-bravo. A redução no crescimento radicular das plântulas de amendoim-bravo pode estar relacionada à diminuição no alongamento das células do metaxilema. Banisteriopsis oxyclada apresenta propriedades itotóxicas e pode ser considerada uma alternativa no controle das plantas daninhas estudadas, com base em produtos naturais.

“…Bocaiuva fruit has a potential as foodstuff due to its chemical composition, high content of protein, lipids and carbohydrates, and has been usually used in the formulation of bakery products, including biscuits and cakes, enriching their flavour and nutrition value (Coimbra & Jorge, ). However, the bocaiuva fruit deserves further attention because besides its nutritional potential, the pulp also presents a significant amount of carotenoids, tocopherols and phenolics (Peres et al, ). Regarding the phenolic content, the presence of these compounds has been associated with several biological processes, such as antimicrobial and antioxidant activities.…”

“…), a fruit palm native to the Cerrado biome of Brazil, have great interest in poultry feeding. In fact, studies show that bocaiuva fruits, besides providing nutrients, contain significant levels of carotenoids, tocopherols and phenolics in their pulp, peel and seeds (Coimbra & Jorge, ; Peres et al, ). However, although the chemical composition of bocaiuva fruits is hypothesized to contribute to metabolic processes when consumed by animals, there are few reports to date regarding the use of this ingredient in animal feeds.…”

The aim of this study was to evaluate dietary supplementation of different levels of dehydrated bocaiuva pulp (DBP) on the productive performance of laying quails, and on lipid oxidation, and quality in their eggs. A total of 120 quails were distributed in a completely randomized design with six treatments (0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% of DBP), five replicates and four birds per experimental unit. To evaluate lipid oxidation, the eggs were collected on five consecutive days at the end of the trial and distributed in a completely randomized experimental design in a 6 × 5 factorial scheme (eggs from quails fed different levels of DBP × evaluated fresh and after 7, 14, 21 and 28 days). The antioxidant potential of diets was improved (p < 0.05) when the DBP was added estimated as 2,2'‐azinobis‐3‐ethylbenzothiazolin‐6‐sulfonic acid (ABTS) free radical scavenging capacity. No effect (p > 0.05) was observed on feed intake, hen‐day egg production and feed conversion (kg/kg and kg/dz). There were no changes (p > 0.05) in the egg weight, Haugh unit, yolk index or eggshell percentage. Although no difference was observed (p > 0.05), when comparing each level with the control, a negative linear effect (p < 0.05) on specific gravity was observed. In addition, only the treatment with 0.5% pulp exhibited lower (p < 0.05) eggshell thickness compared with the control (0%). Thiobarbituric acid reactive substances (TBARS) analysis showed that as the dietary pulp level was increased, malondialdehyde content decreased linearly (p < 0.05) in the egg yolks, regardless of the storage period. Inclusion of DBP in the diets had no effect (p > 0.05) on the concentration of conjugated dienes in the eggs. The diets containing DBP showed a potential antioxidant effect, reducing the degree of lipid oxidation in egg yolk. However, no beneficial effects were observed on performance and egg quality.
