Abstract

 

The water-distilled oil obtained from rhizomes of Daniella Klainei Pierre ex A.Chev (Caesalpiniaceae) from Gabon was examined by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The major constituent is myrcene (55.42%) along with α-pinene (5.39%), α-humulène (8.09%) and Germacrene-D (6.06%). The essential oil possessed antioxidant and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities and it displayed the inhibition of lipid peroxidation. A broth micro dilution method was used to test the oil against twelve strains of bacteria; it exhibited an antibacterial activity against some of the microorganisms.

 

Key words: Daniella Klainei, caesalpiniaceae, essential oil, antioxidant, antibacterial.
