RÉSUMÉ
This work aimed to determine the chemical composition and evaluate the anthelmintic activity of the methanolextracts and fractions from Amphilophium paniculatum and Amphilophium crucigerum against Eiseniafetida. A preliminary phytochemical analysis was performed to assess the presence of groups of secondarymetabolites. The plants were extracted with methanol to obtain the crude extracts. The extracts were submittedto partition with solvents of increasing polarity to obtain the corresponding fractions. The methanolic extractsand the fractions obtained were tested for anthelmintic activity against E. fetida, using albendazole as a positivecontrol. The phytochemical test demonstrated the presence of flavonoids, saponins, and steroids/triterpenes forA. paniculatum and alkaloids, tannins, saponins, and steroids/triterpenes for A. crucigerum. The extracts andfractions of both plants showed a statistically significant decrease of the times of paralysis and death comparedto albendazole. The results obtained showed that the methanolic extracts and fractions of A. paniculatum and A.crucigerum contain compounds that possess anthelmintic activity. The isolation of the substances responsibleof the biological effect described could result in the development of new drugs to treat helminth diseases.
