| ABSTRACT The current study was conducted to determine the effects of the licorice root (Glycyrrhriza glabra) in laying hens diets on performance, egg cholesterol, some plasma parameters and antioxidant capacity. One hundred, 40-week old laying hens were divided into four groups, each group consisted of 25 hens and were placed in individual cages. The mean of the initial body weight of laying hens was 1829.18±9.595 g. Commercial laying hen diet was supplemented with 0, 0.5, 1.0 and 2.0% levels of licorice root powder and four different dietary groups were formed. From the experimental findings, it was ascertained that the licorice root supplementation had no significant effect on egg weight and feed conversion ratio (p>0.05), but feed consumption... |

| ABSTRACT The aim of this study was to assess the effect of selenium-enriched Candida utilis with high contents of organic selenium (Se) and glutathione (GSH) on growth performance, antioxidant capacity and immune function of broiler chickens. A total of 100 healthy 7-day-old male broiler chickens were randomly divided into 5 groups, and fed diets supplemented with (a) Na2SeO3, (b) C. utilis, (c) Se-enriched Saccharomyces cerevisiae, (d) Se-enriched C. utilis, and (e) the control without any supplements. The experiment lasted for 6 weeks and parameters were recorded on day 42. No significant differences in average daily gain were found among the 5 groups. However, Se-enriched C. utilis supplemented in the diet increased activities of glutathione peroxidase... |

| Abstract Uvaia (Eugenia pyriformis Cambess) is a fruit tree native to the Atlantic Forest and that features peculiar aroma and flavor. Although this fruit is highly popular locally, its commercial farming is virtually nonexistent. In addition, limited studies on this fruit have been conducted. Therefore, the present study aimed to investigate the physical, chemical, and functional characteristics of two uvaia fruit populations grown in Salesópolis, SP, Brazil, in order to determine their potential for being consumed both in natura and processed. Uvaia fruits were evaluated as for skin color, whole fruit weight, longitudinal and transversal diameters, seed percentage, pulp yield, pulp firmness, pH, total soluble solids (TSS), total titratable acidity... |

| Abstract The Atlantic Forest is recognized as a biome rich in biodiversity. Cambuci trees (Campomanesia phaea) produce fruits that may be consumed as both fresh and processed forms but are still underutilized. The aim of this study was to describe the physicochemical characteristics and bioactive compounds in cambuci fruits from Brazilian Atlantic Forest, located at Natividade da Serra-SP, Brazil. Cambuci fruits of the fifty-nine accessions were characterized according to fresh weight, pulp yield, peel percentage, longitudinal and transversal diameters (LD and TD, respectively), pH, soluble solids content (SSC), titratable acidity (TA), SSC/TA ratio, ascorbic acid, total phenolic compounds content, and antioxidant activity using the DPPH assay. The... |

| ABSTRACT The ‘BRS Magna’ grapevine has the advantage of adapting to different regions of Brazil and producing juice of good quality. However, it is necessary to define the components of the cropping system, such as the rootstock, for each region. The aim of this study was to characterise the chemical composition and antioxidant capacity of grape juice collected from ‘BRS Magna’ grapevines grown on different rootstock under the tropical conditions of the Sub-middle São Francisco Valley. The grapes were harvested in the Experimental Area of Bebedouro/Embrapa Semiárido, in Petrolina, Pernambuco, Brazil. The treatments corresponded to the ‘IAC 766’, ‘IAC 572’, ‘IAC 313’, ‘Freedom’, ‘Paulsen 1103’, ‘Harmony’ and ‘SO4’ rootstock. The grape juice was prepared... |

| Introduction: Ugni molinae Turcz., (Myrtaceae) is a plant that is distributed in central-southern of Chile, including Juan Fernández Islands. The leaves have been used in folk medicine for diarrhea and oral infections due to their astringent and antiseptic properties. Objective: antioxidant activity of two extracts (ethyl acetate and methanol) from U. molinae leaves was assessed in several assays. Methods: HPLC (high performance liquid chromatography) for chemical analysis and in vitro antioxidant methods. Results: HPLC profiling of both extracts showed the presence of flavan-3-ols (catechin) and gallic acid, flavonoids and caffeic acid derivates as main constituents. These extracts showed significant activity on 2,2-diphenyl-1-picrylhydrazyl (DPPH),... |

| We investigated antioxidant capacity, phenolic content and phytotoxic effects in seven species of fruit native to Brazil: Acrocomia aculeata, Hymenaea stigonocarpa, Tamarindus indica, Byrsonima intermedia, Psidium firmum, Myrciaria cauliflora and Ficus obtusifolia. Phytotoxic effects were assessed from crude ethanol extracts and semipurified fractions. In four of the seven fruits, total phenolic content, as determined by Folin-Ciocalteu assay, was higher in the peel than in the pulp. We found that total phenolic content correlated significantly with antioxidant capacity. High-performance liquid chromatography with diode array detection revealed the presence of the flavonoids quercetin and rutin in some fruits. We also evaluated the allelopathic effects of... |

| In México, banana (Musa sp.) varieties ate used for human consumption as well as for traditional medicine, but the literature lacks information on local diversity and functional justification for their use. Three varieties of dessert bananas (Valery, Morado, and Enano) and one cooking banana (Macho) were collected in a commercial farm in Tuxtepec, Oaxaca, México, at the agronomic maturity stage, and they were physically and chemically evaluated. A random sampling, ANOVA, and Tukey tests were used. As compared to the dessert bananas, the cooking banana (Macho) showed a lower number of hands per banana bunch (6) and of fingers per hands (6), one of the smallest bunch yields (about 12.4 kg), a higher average finger weight (349 g), length (31.7 cm), girth (17... |

| The antioxidant capacity of the crude extract and fractions ofTabernaemontana catharinensis fruits and branches, was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the content of polyphenols, flavonoids, alkaloids and condensed tannins were determined by the spectrophotometric method. The ethyl acetate fraction of the fruits and the n-butanol fraction of the branches showed IC50 of 181.82 µg/mL and 78.19 µg/mL, respectively. All fractions were analyzed by high performance liquid chromatography (HPLC), in the branches were quantified chlorogenic acid in the chloroform (8.96 mg/g), ethyl acetate (4.31 mg/g) and n-butanol (3.33 mg/g) fractions; caffeic acid in the ethyl acetate (5.24 mg/g) and n-butanol (1.81 mg/g); gallic acid (0.52 mg/g)... |

| Two apricot genotypes, 'Gonci magyarkajszi' and 'Preventa' were assayed at three ripening stages for flesh color indices (L*, a*, b*, C* and Hº), contents of total phenolics and vitamin C, and both water- and lipid-soluble antioxidant capacities (ferric reducing antioxidant power; 2,2'-diphenyl-1-picrylhydrazyl scavenging activity; total radical scavenging activity; and Photochem lipid-soluble antioxidant capacity) to compare their dynamics in the accumulation of antioxidant compounds and capacities through ripening. The increase in a*, b* and C* and decrease in Hº during ripening represented a color shift from green to yellow and orange due to carotenoid accumulation. Parallel to carotenoid accumulation, contents of total phenolics and vitamin C and... |

| Abstract: The Cerrado is one of the world's biodiversity hotspots and Brazil’s second largest biome. Many native species of the Brazilian Cerrado provide fruits that have unique sensory characteristics and high nutritional value. This study aimed at characterizing the pulp of Eugenia klotzschiana O. Berg, concerning its proximal composition, bioactive compound content and antioxidant activity. The pulp under study had high moisture (89.47 g kg-1) and caloric (96.07 kcal kg-1) values whereas its contents of protein (0.59 g kg-1) and lipids (2.35 g kg-1) were low. The cerrado pear pulp also had high iron content (16.5 mg kg -1) and dietary fiber (6.45 g kg-1), besides 0.034-0,055 mg kg-1 carotenoids, 8.66 mg kg-1 ascorbic acid and 0.66 mg kg-1 total... |
