| In South American folk medicine members of the genus Myrciaria are used for the treatment of malaria, diarrhoea, asthma, inflammation and post-partum uterine cleansing. The aim of this work was to evaluate its antileishmanial properties (in vitro) of essential oil derived from leaves of Myrciaria plinioides D. Legrand, a plant species that is native in South of Brazil. The essential oil was obtained by hydro-distillation using fresh leaves of M. plinioides. The chemical composition of this essential oil (MPEO, M. plinioides essential oil) was determined by gas chromatography coupled to mass spectrometry (GC-MS). MPEO was assayed in vitro for antileishmanial properties against promastigotes of Leishmania amazonensis and Leishmania infantum, and for... |

| Abstract Despite recent advances in food production technology, food-borne diseases (FBD) remain a challenging public health concern. In several countries, including Brazil, Clostridium perfringens is among the five main causative agents of food-borne diseases. The present study determines antimicrobial activities of essential oils of six condiments commonly used in Brazil, viz., Ocimum basilicum L. (basil), Rosmarinus officinalis L. (rosemary), Origanum majorana L. (marjoram), Mentha × piperita L. var. Piperita (peppermint), Thymus vulgaris L. (thyme) and Pimpinella anisum L. (anise) against C. perfringens strain A. Chemical compositions of the oils were determined by GC–MS (gas chromatography–mass spectrometry). The identities of the isolated compounds... |

| RESUMO: O Rio Grande do Sul é o maior produtor nacional de arroz irrigado por alagamento do Brasil e algumas lavouras cultivam o arroz irrigado há mais de 100 anos. Nos cultivos, são utilizados insumos agrícolas, muitos dos quais apresentam metais pesados em sua composição. Essa preocupação leva em consideração principalmente os elementos não essenciais às plantas, como o Pb, Cr e Cd, e que oferecem risco à saúde humana. Esta pesquisa teve por objetivo quantificar os teores de Cd, de Cr e de Pb no arroz vendido nos estabelecimentos comerciais do RS. As extrações dos elementos das amostras foram feitas pelo método USEPA 3050B. Para as quantificações dos metais, foi utilizada a Espectrometria de Emissão Óptica por Plasma Acoplado Indutivamente (ICP-OES). Os... |

| ABSTRACT This study aims to verify the most suitable substrate formulation based on proportions of earthworm humus and soil to improve the quality of organic strawberries. Vermicomposting generated humus and strawberry seedlings were planted in different humus:soil ratios: (0:100; 20:80; 40:60; 60:40; 80:20 and 100:0, respectively). The proportional conditions were characterized after planting and after 60-day cultivation, plants were harvested, and chemical characterizations of the soil and plants were made. We verified that with an increase of humus content in the substrate, an increase in values of N, P, K, pH and organic matter in soil and dry and fresh mass in shoot area of the plants were noticed. In relation to fruits, pH, humidity and sodium... |
