The chemotherapy of schistosomiasis remains centered in the use of praziquantel, however, there has been growing resistant parasites to this drug. Thus, the aim of this work was to evaluatein vitroschistosomicidal activity of the hexanes/dichloromethane 1 : 1 extract of Brazilian green propolis (Pex), as well as its major isolated compounds artepillin C, caffeic acid, coumaric acid and drupanin againstSchistosoma mansoni. The Pex was active by displaying an IC(50)value of 36.60 (26.26-51.13) mu g mL(-1)at 72 h against adult worms ofS. mansoni. The major isolated compounds were inactive with IC(50)values >100 mu M, however, the combination of the isolated compounds (CM) in the same range found in the extract was active with an IC(50)value of 41.17 (39.89-42.46) mu g mL(-1)at 72 h. Pex and CM induced alteration in the tegument ofS. mansoni, and caffeic acid caused alteration in egg's maturation. Pex displayedin vitroactivity against adult worms' and eggs' viability ofS. mansoni, which opens new perspectives to better understand the synergistic and/or additive effects promoted by both Pex extract and CM against schistosomiasis features.
