Abstract
Citrus aurantium var. dulce (sweet orange) belongs to one of the largest genera of the Rutaceae family. The species of thisgenus are consumed worldwide fresh or in form of beverages. They include well-known crops lemons, oranges, mandarins,grapefruits, and limes. Essential oils (EOs) obtained from this species have great economic value since they are mainly producedfrom the peel of the crops, which are considered waste during their industrial processing. Considering, the aim of this study wasto evaluate the chemical composition of the essential oil (EO) obtained from the peel of Citrus aurantium var. dulce, as well as toassess the biological effects by the means of antioxidant and antibacterial activity. Chemical composition analysis performedusing GC and GC/MS analysis revealed that this EO is a rich source of limonene presented in this sample in the amount of93.86% of the total. Obtained results of antioxidant testing indicate better inhibition of ABTS•+ (68.32 ±3.54%) compared to theDPPH• (8.60 ±1.52%). Moreover, the results of the antimicrobial assessment using the disc diffusion method displayed almostno inhibition power of this essential oil towards G- bacteria and yeast strains, while towards G+ bacterial strains weak inhibitionwas observed.
Keywords: essential oil, Citrus, chemical composition, antioxidant activity, antimicrobial activity
