✦ Synopsis

The essential oil, obtained from fresh leaves of nira (Allium tuberosum Rottl.) by steam distillation, was analysed by HRGC and GC±MS. Sulphur-containing compounds identi®ed account for 84% of the oil. Besides the sulphur compounds commonly reported in the genus Allium, three unusual volatile sulphur-containing components were found and they can be grouped as 1-(methylthio)alk(en)yl alk(en)yl disulphides. The compound identi®ed as allyl 1-(methylthio)ethyl disulphide is described in the literature for the ®rst time. # 1997 by John
