From the petr. ether extracts of the air-dried leaves and branches of Quercus stenophylla MAKINO (Japanese name "Urajirogashi"), n-paraffins, friedelin (I), epi-friederanol (II), friedelanol (III) and taraxerol (IV) were isolated by column chromatography on silicagel, and were identified. In addition, the components of n-paraffins were investigated by gas chromatography, and were confirmed to contain pentacosane (V) (3%), heptacosane (VI) (40%), nonacosane (VII) (28%) and hentriacontane (VIII) (20%).
