Antimicrobial activity and constituents of Coccoloba acrostichoides.

The ethanol extract and fractions from Coccoloba acrostichoides aerial parts were assayed for in vitro antimicrobial activity. The extract was active against the assayed bacteria while most of the fractions also inhibited fungal growth, especially the n-hexane and EtOAc fractions. The isolated beta-sitosterol and betulin were tested, being the last one active against Fusarium oxysporum.
