Atividade ovicida e larvicida do extrato etanólico de Aloe vera L. sobre Haemonchus contortus

Abstract

O objetivo deste trabalho foi determinar a eficacia in vitro do extrato etanolico de Aloe vera L. frente a estagios de vida livre deHaemonchus contortus. O fitoterapico foi produzido com percolacao da polpa do vegetal com alcool absoluto, a 25oC, sendoposteriormente liofilizado. Foram realizados o teste de eclodibilidade de ovos (TEO) e o teste de desenvolvimento larval (TDL), comconcentracoes crescentes (0,78 a 100mg/mL) em seis repeticoes. Para analisar a composicao quimica do fitoterapico, procedeusea marcha fitoquimica completa, analisando qualitativamente a presenca de fenois, taninos, antocianinas, antocianidinas,leucoantocianidinas, estero ides, triterpenos, saponinas, resinas e alcaloides; alem da quantificacao de fenois totais, teste detoxicidade frente Artemia salina e ensaio antioxidante pelo teste de reducao do radical DPPH. O produto obtido a partir de A. veraapresentou eficacia de 94,35 ± 1,13% no TEO, ja no TDL a eficacia foi de 76,03 ± 0,45%, ambos na concentracao de 100mg/mL.Nas analises fitoquimicas, foram encontrados diversos compostos que podem ter contribuido com o efeito anti-helmintico, tantodireta como indiretamente. Os dados da marcha fitoquimica, aliados aos resultados dose-dependentes obtidos nos testes in vitroevidenciam que o extrato produzido possui potencial para combater H. contortus. Novos estudos devem ser realizados buscandomaximizar a eficacia deste extrato, uma vez que foram encontrados resultados excelentes nos testes realizados.
