Abstract

Antimicrobial activity of crude extracts and essential oil of Callistemon viminalis against several pathogenic bacteria and one yeast (Candida albicans) were assessed using sensitivity test and MIC determination test. Hexane extract showed the strongest antibacterial activity compared with other crude extracts. While essential oil of C. viminalis  in particular showed strong anticandidal activity. GC-MS analysis of crude hexane extract and essential oil have identified the presence of eucalyptol, α-pinene, α-phellandrene and D-limonene as active antimicrobial compounds in all analyzed samples.
