ABSTRACT

Essential oils are volatile oils with different compositions according to their source of production and comprise a mixture of substances having different chemical and physical properties. One of the plants containing essential oil is Eucalyptus grandis grown at PT Toba Pulp Lestari (Indonesian company). The purpose of this work is to know the chemical contents and physical properties of essential oil from Eucalyptus grandis as well as to utilize unused leaves at PT. Toba Pulp Lestari to serve as an essential oil. The essential oil of Eucalyptus grandis leaves was extracted using hydrodistillation method, then essential oil is analyzed by GC-MS. The essential oil of Eucalyptus grandis leaves was obtained 0.4 %. The physical properties test with determination of density and refractive index of essential oil respectively were obtained at 0.9143 and 1.4653 nD at 29.4 ºC. The results of GC-MS analysis of essential oil showed 12 components viz. α-pinene (45.21 %), camphene (1.38 %), β-pinene (1.11 %), camphogen (0.74 %), 1,8-cineole (36.55 %), α-campholene aldehyde (0.73 % ), pinocarvone (0.83 %), α-terpineol (8.87 %), β-caryophyllene (1.72 %), spathulenol (0.84 %), elemol (0.85 % ) and 1-nonadecene (1.17 %).
