The essential oil from the tea-leaves was examined by means of gas liquid chromatography; a number of the components present were tentatively identified, and twenty two substances among these components were found to be identical with those found by Takei et al.1) In the present work, isoamyl acetate, salicylaldehyde, benzyl acetate, indole and skatole were recognized on the chromatograms for the first time. Upon completion of the gas chromatographic tests, it was suggested that there were at least four components still remaining unknown. In addition, approximate quantitative analysis is presented for the com position of the major components of the essential oil.
