Atividade antineoplásica e tripanocida de Hovenia dulcis Thunb. cultivada in vivo e in vitro

Resumos

Muitas são as substâncias do metabolismo vegetal que têm despertado grande interesse, principalmente no setor de fármacos. No presente estudo, foram avaliadas as atividades antineoplásica e tripanocida de extratos vegetais de Hovenia dulcis (Rhamnaceae) cultivada sob condições in vivo e in vitro. Extratos metanólicos das folhas de material jovem desenvolvido in vivo e in vitro, exibiram altas porcentagens na inibição do crescimento de todas as linhagens de células tumorais testadas, enquanto extratos etanólicos do pseudofruto mostraram seletividade com elevado percentual de inibição do crescimento celular nas linhagens SP2/0 e BW. Quanto à atividade tripanocida, os extratos aquoso do pseudofruto e metanólico das folhas das plantas germinadas in vivo, apresentaram percentual de inibição em 48 h, de 95% e 100%, respectivamente.


Plants produce a wide range of secondary metabolites, many of which are pharmaceutically important. In this paper were evaluated anti-cancer and trypanocidal activities from Hovenia dulcis (Rhamnaceae) in vivo and in vitro propagated plants. Methanolic extracts of young leaves from in vivo and in vitro material were remarkably active for all tumor cells lines tested, while ethanolic extracts of pseudofruit showed high degree of selectivity against to SP2/0 and BW cells in culture. Mortality of 95 and 100% (48 h) on Trypanosoma cruzi were observed on the aqueous extract of pseudofruit and methanolic extracts of leaves from seedlings.

ABSTRACT

Plants produce a wide range of secondary metabolites, many of which are pharmaceutically important. In this paper were evaluated anti-cancer and trypanocidal activities from Hovenia dulcis (Rhamnaceae) in vivo and in vitro propagated plants. Methanolic extracts of young leaves from in vivo and in vitro material were remarkably active for all tumor cells lines tested, while ethanolic extracts of pseudofruit showed high degree of selectivity against to SP2/0 and BW cells in culture. Mortality of 95 and 100% (48 h) on Trypanosoma cruzi were observed on the aqueous extract of pseudofruit and methanolic extracts of leaves from seedlings.
