GC, GC/MS analysis, and biological effects of <i>Citrus aurantium amara</i> essential oil

Abstract Citrus aurantium amara (sour orange) belongs to one of the largest genera Rutaceae family. The species this genus are consumed worldwide as fresh or in form beverages. They include well-known crops lemons, oranges, mandarins, grapefruits, and limes. industrial processing these fruits produces high amounts waste (around 50%) which is a valuable source essential oils. Since they produced mainly from peel, considered waste, oils have great economic value. In that regard, aim study was evaluate chemical composition oil obtained peel , well assess biological effects by means antioxidant antibacterial activity. Results GC GC/MS analysis characterized EO limonene found amount 90.4% total. activity indicate better inhibition ABTS •+ (44.93 ±1.45%) compared DPPH • (11.03 ±1.08%). Moreover, results antimicrobial assessment using disc diffusion method displayed low potency towards G + − bacteria yeast strains.
