The essential oil was obtained in 0.070% (I), 0.012% (II) and 0.077% (III) yields by steam distillation from the flowers (I), leaves (II) and roots (III) of Plantago asiatica L., which were collected at Higashiosaka-shi in June 1977. Each essential oil was chemically separated into three parts : i.e. neutral, sodium bicarbonate soluble and sodium hydroxide soluble parts. Each fraction was investigated by gas-liquid chromatography (GLC), instrumental analysis and each compound was identified by comparison with the authentic sample. We found that the major components of the essential oil were (I) carvacrol, (II) : 1-octen-3-ol and (III) : linalool and geranyl acetate, and that it contained terpene compounds, aliphatic alcohols, aromatic compounds, phenol compounds and aliphatic fatty acids. They were α-pinene, camphene, limonene, n-hexanol, 3-hexen-1-ol, camphor, 1-terpinen-4-ol, β-caryophyllene, α-terpinyl acetate, nerolidol, guaiacol, cresols, and miscellaneous.
