| Abstract: | Low-boiling compounds escaping during steam distillation of Cryptotaenia japonica Hassk were collected and examined with chromatographies and by the preparation of their derivatives.The following compounds were identified. Six paraffin hydrocarbons: n-pentane, n-hexane, n-heptane, n-octane, isooctane, n-nonane; seven carbonyl compounds: formaldehyde, acetaldehyde, propionaldehyde, n-butyraldehyde, isovaleraldehyde, acetone, 3-methyl-2-pentanone; three esters: n-propyl and isopropyl formates, n-propyl acetate; eight alcohols: methanol, ethanol, n-propanol, isopropanol, isobutanol, sec-butanol, isopentanol, n-octanol; two sulfides: dimethyl and methyl ethyl sulfides; six monoterpene hydrocarbons: α-pinene, camphene, β-pinene, sabinene, myrcene, limonene. |
