The objective of this work is to study the organoleptic and physicochemical properties of the essential oil of Limon (Citrus limon) grown in Collo, Skikda city (Algeria). The evaluation of the yield of essential oil extracted by cold expression is: 1.0%. The qualitative and quantitative analysis by (GC / MS) of the essential oil allowed to identify 53 compounds which represent: 99.938%, the main ones being: Limonene (61.647%), β.-Pinene (13.852%), γ.-Terpinene (9.959%) followed by other low-molecules: α.-Pinene (2.279%), Myrcene (1.888%), α.-Citral (1.702%), β.-Citral (1.046%), β.-Bisabolene (1.026%) totaling approximately: 93.399%. The density is: 0.855 ± 0.005. The measurement of the refractive index calculated and brought to 20°C is of low light refraction: 1.4700 ± 0.005. The boiling and evaporation index are values: (180-188°C).
