RESUMO:A cúrcuma é o rizoma limpo, em boas condições, seco e moído da Curcuma longa L., uma planta herbácea da família Zingiberaceae. Visando novas alternativas para o controle da esquistossomose, os extratos de Curcuma longa L. foram testados para a avaliação da atividade moluscicida contra caramujos adultos da espécie Biomphalaria glabrata, e toxicidade (ensaio de letalidade com Artemia salina). A oleoresina e o óleo essencial de cúrcuma foram ativos contra Artemia salina (CL 50 = 80,43 e CL 50 = 319,82 µg/mL, respectivamente) e também ativos contra os indivíduos adultos de Biomphalaria glabrata (CL 50 = 58,3 e CL 50 = 46,73 µg/mL, respectivamente). A partir dos resultados obtidos pôde ser concluído que ambos os extratos podem constituir uma alternativa no controle da população desses caramujos e na redução da esquistossomose.Unitermos: cúrcuma, atividade moluscicida, Biomphalaria glabrata, Artemia salina.ABSTRACT: "Bioactivity evaluation of the turmeric (Curcuma longa L., Zingiberaceae) extracts in Artemia salina and Biomphalaria glabrata". The turmeric is the clean rhizome at good conditions, dried and powdered of Curcuma longa L., an herbaceous plant of Zingiberaceae family. Aiming new alternatives for Schistosomiasis control, the Curcuma longa L. extracts were tested for molluscicidal activity evaluation against adult snails of Biomphalaria glabrata specie, and the toxicity (Brine Shrimp Lethality-BSL-bioassay). The oleoresin and the essential oil of turmeric were active against Artemia salina (CL 50 = 80.43 and CL 50 = 319.82 µg.mL -1 , respectively) and also active against the adult snails of Biomphalaria glabrata (CL 50 = 58.3 and CL 50 = 46.73 µg.mL -1 , respectively). From the obtained results it was concluded that both extracts can constitute an alternative to population control of these snails and in the reduction of Schistosomiasis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
