    The pepper tree Schinus molle L. is an evergreen ornamental plant belonging to the Anacardiaceae family, native to South America and widespread throughout the world. It has biological activities and is used in folk medicine. This paper aims to contribute to a deeper knowledge of its chemical composition and biological properties. S. molle leaf extracts were obtained by sequential extraction with solvents of different polarities and subsequently tested on the HL-60 human leukaemia cell line to define a possible cytotoxic activity. Among the investigated extracts, the petroleum ether extract revealed a high cytotoxic activity, and its chemical composition was further investigated. By a silica column chromatography, eight fractions were obtained, and their compositions were determined by GC-MS analysis. Compounds and relative abundance differed widely among the fractions; sesquiterpenes resulted the main component and alcoholic sesquiterpenes the most abundant

    No município de Penápolis e região, os fatores econômicos, climáticos e políticos, influenciaram na substituição da cultura do café por outras atividades agropecuárias, como a cana-de-açúcar e a pastagem, oprimindo assim, a agricultura familiar tornando-a inviável, provocando o êxodo rural em busca de outras fontes de renda. O objetivo desse trabalho é o de verificar a viabilidade de manter o agricultor familiar na região através do resgate da cafeicultura com manejo agroecológico que supere as adversidades ambientais e socioeconômicas. A implementação de uma lavoura experimental de café com princípios agroecológicos e o levantamento de dados dos produtores e de suas propriedades, vislumbra o fortalecimento da cultura na região, com novos modelos de produção. Conclui-se que a possibilidade de intensificação do cultivo do café com vertente agroecológica na região de estudo, como uma opção de resistência ao avanço da cana-de-açúcar, depende em grande parte de uma decisão política de estímulo e de motivação dos agricultores familiares

    A victory for Italian same-sex couples, a victory for European homosexuals? A commentary on Oliari v Italy

    Get PDF
    In Oliari and others v. Italy the European Court of Human rights established for the first time that the legislator’s failure to guarantee a legal framework recognizing non-marital same-sex relationships constitutes a violation of the right to respect for private and family life under article 8 of the European Convention of Human Rights. This article aims to underline positives and negatives in judges’ reasoning. Particularly, it will be underlined the relevance of the judgment both as a critique on major contradictions characterizing Italian institutional debate around the issue of same-sex partnerships, and as a further step in the progressive application of article 8 ECHR to protect same-sex individuals committed in an intimate relationship. Such result is indeed achieved by referring expressly to the US Supreme Court judgment in Obergefell v. Hodges, which is uncommon for the Strasbourg Court and should not be overlooked for future cases.However, the article observes how the Chamber surprisingly failed ascertaining a possible violation of the right of private and family life in conjunction with the non-discrimination principle. This risks limiting the effects of its reasoning to the Italian situation only. Moreover, it is disappointing to notice that the European Court did not even examine Italy’s violation of the right to marry under art.12 of the Convention, and contrarily granted a wide margin of appreciation to the States. At present, same-sex marriage still remains “taboo” for the ECtHR.Effective Protection of Fundamental Rights in a pluralist worl
