ABSTRACT
Ethanol, methanol and water extracts representing mostly native plant species found in the Amazon region were prepared, respectively, by maceration, continuous liquid-solid extraction and infusion, followed by evaporation and freeze-drying. The freeze-dried extracts were tested for lethality toward Aedes aegypti larvae at test concentrations of 500 mg / mL. In general, methanol extracts exhibited the greatest larvicidal activity. The following 7 methanol extracts of (the parts of) the indicated plant species were the most active, resulting in 100% mortality in A. aegypti larvae Tapura amazonica Poepp. (root), Piper aduncum L. (leaf and root), P. tuberculatum Jacq. (leaf, fruit and branch). and Simaba polyphylla (Cavalcante) W.W. Thomas (branch).
RESUMO
Extratos aquosos, etanólicos e metanólicos, representando principalmente espécies vegetais nativas encontradas na região Amazônica, foram preparados, respectivamente, por infusão, maceração e extração contínua líquido-sólido, seguida de evaporação e liofilização. Os extratos liofilizados foram testados para atividade contra larvas de Aedes aegypti, na concentração única de 500 mg / mL. Os extratos metanólicos foram, em geral, os que apresentaram maior atividade larvicida. Os seguintes 7 extratos metanólicos das (partes das) espécies vegetais indicadas foram os mais ativos, provocando 100% de mortalidade em larvas de A. aegypti Tapura amazonica Poepp. (raiz), Piper aduncum L. (folha e raiz), P. tuberculatum Jacq. (folha, fruto e galho) e Simaba polyphylla (Cavalcante) W.W. Thomas (galho).
