ABSTRACT
SUMMARY The molluscicidal activity of the leaf powder of Moringa oleifera and lyophilized fruit powder of Momordica charantia against the snail Lymnaea acuminata was time and concentration dependent. M. oleifera leaf powder (96 h LC50 197.59 ppm) was more toxic than M. charantia lyophilized fruit powder (96 h LC50 318.29 ppm). The ethanolic extracts of M. oleifera leaf powder and Momordica charantia lyophilized fruit powder were more toxic than other organic solvent extracts. The 96 h LC50 of the column purified fraction of M. oleifera leaf powder was 22.52 ppm, while that of M. charantia lyophilized fruit powder was 6.21 ppm. Column, thin layer and high performance liquid chromatography analysis show that the active molluscicidal components in M. oleifera leaf powder and lyophilized fruit of M. charantia are benzylamine (96 h LC50 2.3 ppm) and momordicine (96 h LC50 1.2 ppm), respectively. Benzylamine and momordicine significantly inhibited, in vivo and in vitro, the acetylcholinesterase (AChE), acid and alkaline phosphatase (ACP/ALP) activities in the nervous tissues of L. acuminata. Inhibition of AChE, ACP and ALP activity in the nervous tissues of L. acuminata by benzylamine and momordicine may be responsible for the molluscicidal activity of M. oleifera and M. charantia fruits, respectively. .
RESUMO
RESUMO A atividade moluscicida do das folhas de Moringa oleifera e do liofilizado das frutas da Momordica charantia contra o caramujo Lymnaea acuminata é dependente do tempo e da sua concentração. O da folha da M. oleifera (96 h LC50 197.59 ppm) foi mais tóxico do que o liofilizado da fruta da M. charantia (96 h LC50 318.29 ppm). Os extratos etanólicos do de folha da M. oleifera e do liofilizado da fruta da M. charantia foram mais tóxicos do que outros extratos orgânicos solventes. O 96 h LC50 da fração purificada por coluna do das folhas da M. oleifera foi 22.52 ppm enquanto que o liofilizado do fruto da M. charantia foi 6.21 ppm. Coluna, camada fina e a alta performance da análise da cromatografia líquida mostram que os componentes ativos moluscicidas do da folha da M. oleifera e do liofiliizado da fruta da M. charantia são a benzilamina (96 h LC50 22.3 ppm) e a momordicina (96 h LC50 1.2 ppm), respectivamente. A benzilamina e a momordicina inibiram de maneira significante in vivo e in vitro a acetilcolinesterase (AChE), as atividades das fosfatases alcalina e ácida (ACP/ALP) nos tecidos nervosos da L. acuminata. A inibição da atividade da AChE, ACP e ALP nos tecidos nervosos da L. acuminata pela benzilamina e momordicina podem ser responsáveis pela atividade moluscicida da M. oleifera e dos frutos da M. charantia, respectivamente. .
