Steam volatile oil was obtained by steam distillation of A. fistulosum Linn. var. caespitosum Makino. It was chemically separated into 3 fractions. The neutral fraction was investigated by column chromatography, gas chromatography, IR, NMR and mass spectrometry. Each component was further identified by comparisons with authentic compounds. Eight compounds were identified; dipropyl disulfide, dipropyl trisulfide, trans- and cis-3,5-diethyl-1,2,4-trithiolane, 2-undecanone, 2-tridecanone, 2-undecanol and 2-tridecanol.
