Avaliação preliminar da ecotoxicidade dos extratos das folhas e cascas de Cestrum intermedium Sendtn. (Solanaceae)

Abstract

This work presents a theoretical and practical approach for preliminary ecotoxicity evaluation and phytochemical profile of Cestrum intermedium Sendtn., a native from Brazil Solanaceae species, broadly used as ornament for it’s attractive flowers release a pleasant odor. In some southern regions is considered to be the most important toxic plant, for causing liver toxicity in cattle resulting in death most of the times. For those reasons, a preliminary ecotoxicological study was developed, since only veterinarian toxicological studies were ever developed. Leaves’ and barks’ gross extracts and it’s fractions were evaluated in acute toxicity for salt water microcrustacean (Artemia salina) and Aedes aegypti larvae, showing toxic activity. Bioessays’ results were evaluated observing results from phytochemical essays, providing a active secondary metabolic panorama. These information are useful for evaluating environmental applications viability, considering more deeper toxicological studies.
