| Physalis peruviana is an exotic fruit that belongs to the Solanaceae family and which has recently started to be produced in Brazil, mainly in the Southern region. Once there is few data regarding its chemical composition, this work presents the centesimal and mineral composition and the fatty acid profile of the lipidic fraction of Physalis peruviana. Concerning the centesimal composition, Physalis presented high contents of ashes and total lipids, 0.8 and 3.16 g.100 g-1, respectively. In its mineral composition, K, Mg, Ca and Fe were the main elements, and Fe is present in concentrations higher than those in the common sources such as beans. The lipidic fraction presented predominance of the linoleic acid (72,42%) in its composition. |

| Diferentes sistemas solventes foram aplicados para determinar a eficiência de extração de compostos com capacidade antioxidante em bagaço de uva, importante subproduto do processo de vinificação. Realizou-se a quantificação de compostos fenólicos totais, antocianinas totais e atividade antioxidante nos extratos de bagaço de uva Vitis vinifera das variedades Tannat e Ancelota, provenientes da região de Videira, Santa Catarina. A atividade antioxidante foi determinada pelos métodos ABTS, FRAP e β-caroteno/ácido linoléico. Conteúdos de compostos fenólicos totais em acetona 50 e 70% foram maiores nas duas variedades, enquanto que os conteúdos de antocianinas totais extraídos em ambas as variedades foram maiores no solvente etanol em concentrações de 50 e 70%.... |

| The aim of this study was to evaluate the content of the phenolic compounds and anthocyanins and the antioxidant activity of blueberry (Vaccinium sp.) cultivars grown in Brazil. The Folin-Ciocalteau method was applied in order to quantify the phenolic compounds and ABTS, DPPH, FRAP, and β-carotene/linoleic acid methods were applied in order to evaluated antioxidant activity. The phenolic compounds content ranged from 274.48 to 694.60 mg GAE.100 g-1 of fresh weight (FW). Anthocyanins content ranged from 40.62 to 378.31 mg.100 g-1 FW for Bluecrop and Tifblue cultivars, respectively. Antioxidant activities assessed by ABTS, DPPH and FRAP methods presented significant differences among the studied cultivars ranging from 1238.48 to 2445.96, 1014.24 to 2055.06... |
