Abstract
The essential oil was obtained in 0.0027% yield by steam distillation of fresh bud from Medara (Aralia elata Seem. var. subinermis Ohwi), collected from Ashigara-shi in May, 1992. The components of the essential oil were investigated by gas chromatographic and mass spectrometric analyses.
Volatile components including 47 monoterpenoids, 11 sesquiterpenoids, and 78 miscellaneous compounds were found present in the essential oil. Characteristic compounds of the essential oil were borneol, 4-terpineol, α and β-pinene, camphene, limonene, (Z) and (E) -2-hexenal, (E) -2-heptenal, (2E, 4E) -2, 4-heptadienal, (E) -2-nonenal, (2E, 4E) -2, 4-nonadienal, (2E, 4E) -2, 4-decadienal, 3- (methylthio) propanal, perillene, 2-ethylfuran, (Z) -jasmone, sabinene hydrate and 4-hexanalide.
