Chemical Composition and Antimicrobial Activity of the Essential Oil of the Leaves of Feronia elephantum (Rutaceae) from North West Karnataka

Abstract

The essential oil of the leaves of Feronia elephantum Corr. was analyzed by gas chromatography and gas chromatography/mass spectrometry. The main constituents were β-pinene (28.4%), Z-anethole (22.1%), methyl chavicol (12.0%) and E-anethole (8.1%), among thirty-three identified compounds, which represented 92.6% of the total oil. The antimicrobial activity was tested against five Gram-positive and eight Gram-negative bacteria, and four fungi. The oil was active against Micrococcus luteus (Gram-positive bacterium), Proteus mirabilis (Gram-negative bacterium), Penicillium chrysogenum and Aspergillus niger (fungi) with MIC values of 0.31±0.06, 0.52±0.10, 0.20±0.50 and 0.26±0.52 mg/mL, respectively.
