  Background: Vochysia divergens is native to the Amazon Basin and considered an invasive species in the Brazilian Pantanal. In this work, the ethanolic extract of V. divergens leaves was chemically investigated and evaluated in vitro against Schistosoma mansoni adult worms together with the isolated compounds. Methods: The samples were available at concentrations of 12.5, 25, 50 and 100 μM. The parasites were kept for 4 days and monitored every 24 h to evaluate their viability and motor activity comparing with the positive control praziquantel. The cell viability of isolated flavones as determined by XTT assays in V79 cells. Results: The flavones 3′,5-dimethoxy luteolin-7-O-β-glucopyranoside, 5-methoxy luteolin and 3′,5-dimethoxy luteolin were isolated from V. divergens. Flavone 5-methoxy luteolin caused the death of 2..
