Abstract
Antimicrobial and free radical scavenging activities of EtOAc, n-BuOH and the remaining H2O extracts of aerial parts of Geranium glaberrimum Boiss et Heldr. Geranium stepporum Davis and Geranium psilostemon Ledeb were investigated in this study. Broth microdilution and spectrophotometric DPPH methods were used to test antimicrobial and free radical scavenging activity, respectively. All tested extracts showed free radical scavenging activity. The EtOAc extracts of all studied plants were found to possess the highest antimicrobial and free radical scavenging activity. Among the tested extracts, the EtOAc extract of G. psilostemon is considered the most active against the tested microorganisms. All EtOAc extracts were shown to possess higher free radical scavenging activity than that of ascorbic acid at 50 μg/mL.
