To elucidate the constituents of the essential oil from the leaves of Citrus depressa HAYATA, the plant growing in Amamioshima (Kagoshima Prefecture) was collected and the essential oil obtained by steam distillation of the leaves was separated into three fractions (neutral, phenolic, and carboxylic acid). These fractions were examined by gas-liquid chromatography, infrared and nuclear magnetic resonance spectroscopy, and 24 kinds of compound (3-hexen-1-ol, thymol, palmitic acid, etc.) were newly detected, besides the known seven compounds (γ-terpinene, etc.).
