| ABSTRACT A study was conducted to evaluate the effect of chlorogenic acid (ChA) added pre-cooling and its combination with caffeine added during warming on cooled-stored boar semen parameters. Ten ejaculates were diluted in commercial extender with or without 4.5mg/ml ChA and stored at 15°C. After 0, 24 and 72 hours of storage, aliquots of these doses were taken and incubated at 37°C in the presence or absence of 8.0mM caffeine. Semen quality was evaluated after 10 and 120 minutes of incubation. The ChA increased (P <0.01) the sperm motility, viability, acrosomal integrity and the percentage of spermatozoa with high mitochondrial activity (PMHA), however, decreased (P <0.01) the malondialdehyde (MDA) concentration. Caffeine increased (P<0.05) the... |

| In Brazil, the cassava leaf meal (CLM) has been used to strive against undernourishment because it is a high source of vitamins and minerals. However, the wide variation in the chemical composition of the different cultivars, as well as their antinutritional substances may be a restriction to their uses. The levels of some antinutrients in CLM from five cultivars at three ages of the plant (TAP) were investigated, in order to select the cultivars and plant ages that would be more appropriate for human consumption. The lowest contents of antinutrients were observed in the 12-month old plants, except for nitrate and hemagglutinin from which the lowest contents were found for the 17 month old ones. The cultivar IAC 289-70 had the lowest antinutrient levels,... |

| ABSTRACT Condensed tannin (CT) concentrations in plants are influenced by species, plant part, season, growth phase, environmental conditions, disease and defoliation. The objectives of this study were to determine the effects of edaphoclimatic factors on the concentration of CT stored in leaves and bark from Mimosa tenuiflora (Wild.) Poiret and Anadenanthera macrocarpa (Benth.) Brenan., collected at three distinct locations in northeastern Brazil. At each study site, sampling was carried out by randomly selecting five trees, each tree represented one replication and samples of leaves and bark of each plant species was collected. Soil samples were collected near the base of each plant for moisture, physical and chemical analysis. Meteorological data from... |

| Abstract: The objective of this work was to evaluate the effect of the Y-trellis (YT) and vertical shoot-positioned (VSP) training systems on the incidence and severity of Botrytis cinerea, on cluster compactness, and total polyphenol (TP) contents of 'Sauvignon Blanc' grapevine in the municipality of São Joaquim, in the state of Santa Catarina, Brazil. Field trials were carried out in a randomized complete block design during the 2013/2014 and 2014/2015 crop seasons, with assessments performed at harvest. The YT system causes a higher incidence and severity of botrytis bunch rot under climatic conditions favorable to the pathogen, as well as greater cluster compactness, than the VSP system, without affecting the content of total polyphenols of 'Sauvignon... |

| The fermented herbal juices are capable of curing and preventing diseases and reducing the aging progress. The present study was performed to investigate the fermentation of Phyllanthus emblica fruit by Lactobacillus paracasei HII01 with respect to carbon sources, polyphenols, and antioxidant properties. The physical changes, for instance, color, odor, taste, turbidity and gas formation, throughout the fermentation process was manually monitored. The fermented product was rich in polyphenolic content. The acid content and pH of the product were under the norms of Thai community product standards. Antioxidant properties of the fermented product were proved using ABTS, and FRAP assays. Chelation based study suggested that fermented P. emblica fruit juices... |

| Abstract This study investigated the in vitro and in vivo antioxidant activities of polyphenol extracted from black garlic. Black garlic polyphenol (BGP) was extracted from black garlic. The in vitro antioxidant activities of BGP were determined using DPPH·, OH and O2– radical scavenging assays. The in vivo antioxidant activities were determined by detecting the malondialdehyde (MDA) content and superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in mice. Results showed that, the DPPH· radical inhibition rate of 200 and 250 μg/mL BGP was equivalent with Vc (P > 0.05). With concentration of 400 and 500 μg/mL, the OH radical inhibition rate of BGP was slightly lower than Vc (P > 0.05). The O2– radical inhibition rates of 200, 400,... |

| 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 pH, polyphenol content and polyphenol oxidase (PPO) activity in stem end, middle, and bud end of Norin No. 1 potatoes, one of processing varieties in Japan, were measured to investigate their respective distributions. The stem end area had a higher pH and PPO activity in the three areas. This result points out that careful harvesting and postharvest handling are needed especially at the stem end area of potatoes because of its high PPO activity. |

| Abstract: The objective of this work was to validate a fast method with low-solvent use, for the analysis of trans-resveratrol and quercetin in red wines. The wines were prepared, using a classical method, from the grape (Vitis vinifera) cultivars Cabernet Franc, Cabernet Sauvignon, Malbec, Merlot, Petit Verdot, Pinot Noir, Ruby Cabernet, Syrah, Tannat, and Tempranillo. Samples were filtered and analyzed by high-pressure liquid chromatography (HPLC) with a diode array detector (DAD), at 306 and 371 nm, for trans-resveratrol and quercetin, respectively. An octylsilane column was used, and the mobile phase was composed by a gradient of methanol, water, and formic acid. The method was validated according to the following figures of merit: specificity,... |
