Ferrato (Tuscany, Italy) were investigated by GC and GC/ MS. Several classes of compounds were detected, of which sesquiterpenes, (representing the 25.6% of the total oil from C. paniculata and 74.5% from C. rupestris), alcohols (27.8% in C. paniculata and 4.3% in C. rupestris) and aldehydes (12.0% C. paniculata and 2.0% in C. rupestris) were the most abundant, followed by acids, monoterpenes, esters, ketones, hydrocarbons, diterpenes and miscellaneous. A series of unidentified compounds were also detected. Differences in qualitative and quantitative composition were evidenced and discussed.
