Abstract

O presente estudo foi desenhado para verificar as propriedades anti-helmínticas de algumas plantas locais. Sementes de Amomum (A.) subulatum e Vitex (V.) negundo em diferentes solventes foram submetidas a análise de atividade anti-helmíntica in vitro (ensaio de motilidade de adultos; AMA e teste de eclosäo de ovos; EHA) e in vivo (teste de reduçâo da contagem de ovos nas fezes; TRCOF), usando o Haemonchus (H.) contortus como modelo experimental no protocolo de teste. Os resultados dos testes AMA, EHA e TRCOF foram analisados estatisticamente por meio de regressäo linear e teste de Duncan. No teste AMA, na concentraçâo de 50 mg mL-1, o percentual de mortalidade de H. contortus foi maior com o uso de A. subulatum do que com V. negundo, enquanto, no teste EHA, A. subulatum apresentou maior açâo ovicida (LC50=14,2 pg mL- 1) do que V. negundo (LC50= 65,7405 pg mL-1). O TRCOF também indicou a melhor eficacia do uso de A. subulatum do que de V. negundo contra a infecçâo natural de parasitas gastrointestinais (GI). O extrato bruto seco das plantas utilizadas neste estudo apresentou 29,6% a 57,7% de atividade anti-helmíntica. A taxa de reduçâo observada com o uso de A. subulatum (3 g kg-1) foi maior que com o uso de V. negundo (7 g kg-1). Em relaçâo â análise da eficacia dos solventes utilizados para o extrato de plantas, o acetato de etila e o clorofórmio apresentaram maior açâo ovicida em vermes adultos (testes in vitro), enquanto o extrato bruto metanólico aquoso apresentou maior eficácia do que os extratos brutos secos em testes in vivo. Consideramos vantajoso documentar o conhecimento indígena relativos aos procedimentos científicos padronizados, para sua validaçâo. Este estudo irá servir de motivaçâo para que os agricultores façam escolhas melhores referentes ao cultivo das plantas indígenas devido âs suas diferentes eficácias comprovadas, servindo como alternativa para a abordagem preventiva contra as infecçoes parasitarias GI.

Alternate abstract:

The current study was designed to check the anthelmintic activities of some local plants. Seeds of Amomum (A.) subulatum and Vitex (V.) negundo in different solvents were subjected to in vitro (adult motility assay; AMA and egg hatch assay; EHA) and in vivo (faecal egg count reduction test; FECRT) anthelmintic activity testing protocols using Haemonchus (H.) contortus as an experimental model. The results of AMA, EHA, and FECRT were statistically analysed through linear regression and Duncan multiple range test. In AMA test, at 50 mg mL-1 concentration, the percent mortality of H. contortus was higher in A. subulatum than V. negundo, whereas, in EHA test, A. subulatum was proven better ovicidal (LC50=14.2 pg mL-1) than V. negundo (LC50= 65.7405 pg mL-1). The FECRT also indicated the better efficacy of A. subulatum than V. negundo against natural infection of gastrointestinal (GI) parasites. The crude powder of plants used in this study showed 29.6% to 57.7% anthelmintic. The reduction rate was found higher for A. subulatum (3 g kg-1) as compared to V. negundo (7 g kg-1). Reagrding efficacy analysis of solvents used for plants extract, ethyl acetate and chloroform were found better in increasing ovicidal activity in adult worms (in vitro testing), whereas, the crude aqueous methanol was found better than the crude powders in in vivo testing. It will be beneficial to document the indigenous knowledge to standard scientific procedures for their validation. This study will help to motivate the farmers to make a better choice of cultivation of the indigenous plants because of their varying efficacies as an alternative preventive approach against the GI parasitic infections.
