The volatile components other than isothiocyanates in the autolytic hydrolysates of W. japonica roots were examined.Hydrogen sulfid was detected in the absorption vessels containing 5 % solution of Pb(OA_C)_2 by heating the hydrolysate. Presence of volatile mono-, di- and trisulfides was suggested in the hydrolysate by the traping with 3 % HgCl solution. Two kind of carbonyl compounds were isolated in the form of the hydrazones by the absorption vessel containing 0.2 % 2,4-dinitrophenyl-hydrazine. Those compounds were purified by column chromatography and identified as 2,4-dinitrophenyl-hydrazones of acetaldehyde and that of methyl-ethyl ketone by the analyses of their infrared absorption spectra and by paper chromatography.Ammonia and aliphatic primary amines were detected in the steam distillate of the digeste of W. japonica roots by the distillation at pH 10.5.
