New sulphur compounds in Bulgarian rose essential oil were investigated as follows: the steam distilled oil of the rose petals was fractionated by distillation, column chromatography and high‐performance liquid chromatography. GC and GS‐MS were employed for identification. In this analysis, 16 sulphur compounds were identified, and n ‐butyl methyl disulphide, dimethyl trisulphide, n ‐hexyl methyl disulphide, 3‐(4‐methylpent‐3‐enyl)thiophene, 3‐methyl‐2‐(3‐methylbut‐2‐enyl)thiophene, 3‐(4,8‐dimethyl‐nona‐3,7‐dienyl)thiophene, α‐mintsulphide, 4‐(4‐methylpent‐3‐enyl)‐1,2‐dithiacyclohex‐4‐ene, 1,2‐epithiohumulene, 4,5‐epithiohumulene and 4,5‐epithiocaryophyllene were identified for the first time in rose oil. These compounds were found to contribute significantly to the odour of rose essential oil.
