42 & Carryophyllne oxide & 1588 & 1582 & 0.63 & 0.07 & 1970 The major identified compounds (>10%) were limonene, (_E_)-\(\beta\)-ocimene, and (_Z_)-\(\beta\)-ocimene, with percentages on the total oil of 24.29, 21.89, and 12.88% on a non-polar DB-5 ms capillary column, and 23.16, 27.15, and 16.03 %, on a polar HP-INNOWax capillary column, respectively. All the quantified constituents accounted for the 98.18% and 98.15% of the whole EO, calculated as the sum of the integrated peak areas of identified compounds with respect to the total peak area in gas chromatograms. The qualitative and quantitative composition of the EO from _H. laricifolium_ is reported in Table 1, whereas the GC-EIMS chromatograms are shown in Figures 2 and 3.
