A Study on Low-boiling Chemical Constituents of Cryptotaenia japonica HASSK

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: a-pinene, camphene, β-pinene, sabinene, myrcene, limonene.
