The aroma volatiles of a desert parsley were analysed using routine procedures, and 45 constituents were positively identified, including 11 not previously reported as parsley leafvolatiles. One component, 2-(p-tolyl)propan-2- 01, is a new aroma volatile and, together with pmentha-1,3&triene, may be unique to parsley. Major constituents of the sample were 4-methoxy-6-(prop2-enyl)benzo-1,3_dioxolan (myristicin), 4,7_dimethoxy-5-@rop2-enyl)benzo-1,3 dioxolan (apiole), /3-phellandrene, p-mentha-1,3&triene and Cisopropenyl-1-methylbenzene. Aroma assessments during GC showed that apiole, in particular, had desirable parsley odour character.
