Antioxidant and antimicrobial activities of different solvent extracts of the rhizomes of <i style="mso-bidi-font-style: normal">Curcuma leucorrhiza </i>Roxb.

Abstract

The present investigation was conducted to examine the antioxidant and antimicrobial activities of different solvent extracts of the rhizome of <i style="mso-bidi-font-style:normal">Curcuma leucorrhiza</i> Roxb. against four human pathogenic bacterial strains and four plant pathogenic fungal strains. The chloroform extract showed the highest scavenging property while the petroleum ether extract showed the highest antibacterial and antifungal activities. For all extracts, the minimum bactericidal concentrations (MBCs) were higher than the minimum inhibitory concentrations (MICs).
