Abstract
The constituents of the essential oil from Aster subulatus Michx. have been studied. The essential oil odtained in 0.03% yield by steam distillation was treated with 5%-sodium carbonate, then with 5%-sodium hydroxide solution, and was separated into the three parts; neutral, sodium carbonate soluble, and sodium hydroxide soluble part. The each part was separated by column chromatography and gas chromatography.
α-Pinene, camphene, β-pinene, β-myrcene, limonene, p-cymene, n-C13H28, hexanol, 3-octanol, trans-linalool oxide, cis-linalool oxide, linalool, α-copaene, fenchyl alcohol, 4-terpineol, β-caryophyllene, pinocarveol, α-terpineol, α-humulene, α-muurolene, butyric acid, valeric acid, isovaleric acid, caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, o-cresol, eugenol, isoeugenol and carvacrol have been identified through their infrared, mass, nuclear magnetic resonance spectra and chemical methods.
