Sawdust of Lauan (500Kg)collected at a saw-mill in Naha City,was steam distilled,and the oil was obtained.The oil was then successively washed with 3% sodium hydroxide and water,which was evaporated off after drying over sodium sulfate,yielding a neutral material(820g).This substance was divided by fractional distillation into llparts.These fractions were gas chromatographed and investigated by infrared spectroscopy. As the result,the next facts were known:1.All components of the wood oil of Lauan obtained by steam distillation are terpene hydrocarbons,and most of them are sesquiterpenoids. 2,Fractions 5 to 7 show three main peaks in the gas chromatography.One of them areidentified as calarene,the other asα-gurjunene. 3.Fractions 8 to ll show two main peaks in the gas chromatography. Thecomponent of one of the peaks is the main component of the wood oil,the content being 35.09%.The content of the component of the other peak is about 8%. The chemical structure of them have been under investigation by the author.
