Chemical Composition of Essential Oils from Flowers, Leaves and Peel of Citrus aurantium L. var. amara from Tunisia

Abstract Flowers, leaves and peel oils of Citrus aurantium L. var. amara from Tunisia (Nabeul) have been studied by GC-FID and GC/MS. Remarkable differences were found between the constituent percentages of the different studied organs. The most important compounds from the neroli oil (flowers) were linalool (34.4%), linalyl acetate (11.3%) and limonene (10.9%). In the petitgrain oil (leaves), the main components were linalool (36.8%), linalyl acetate (22.1%) and α-terpineol (11.7%). The major constituent of the peel oils was found to be limonene (90.6%).
