Characterisation of volatile composition of white salsify (Tragopogon porrifolius L.) by headspace solid-phase microextraction (HS-SPME) and simultaneous distillation-extraction (SDE) coupled to GC-MS

► The volatile composition of white salsify roots was evaluated. ► Two analytical procedures were used SPME and SDE. ► More than 80 compounds of different chemical families were identified. ► SPME identified alcohols and hydrocarbons very important in sensory perception. ► SDE extracts esters and terpenoids of high molecular weight.
