Abstract

In this study, kaffir lime peel was used for extraction of essential oil by hydrodistillation and evaluation of physico-chemical characteristics. The yield of essential oil was 1.8 %. The physico-chemical parameters averaged specific gravity (0.8587g/cm3), acid index (0.667 mg KOH/g), ester index (4.203 mg KOH/g), refractive index (1.469), rotator power +3. Twenty-three components were classified in kaffir lime peel oils. The result of GC-MS revealed that the oil is extremely rich in α-pinene (35.54 %), Eucalyptol (20.902 %), camphene (4.384 %), bicyclo[3.1.1]hept-3-en-2-one (7.794 %), caryophyllene (1.225 %), endo-borneol (4.147 %), bornyl acetate (4.065%). The aim of this study is to promote for further research on extraction enhancement and application of that constituents to cosmetics, medicine and food industries to enhance antioxidant and anti-bacterial capabilities create more useful formulations
