Cytotoxic Activity of Six Samples of Brazilian Propolis on Sea Urchin (Lytechinus variegatus) Eggs

Table 1

Cytotoxic activity, (*) expressed as percent of affected sea urchin (Lytechinus variegatus) embryos, of methanol extract (MeOH) and hexane, chloroform (CHCl3), ethyl acetate (EtOA), and methanol (MeOH) fractions at 32 µg mL−1 (see text) from samples (**) of Brazilian propolis. No effect was observed in tests using ethanol (control).
