Table 3: _Cont._peninsula. One chemotype was characterized by the predominance of camphor in the aromatic fraction, while a second was defined by the predominance of 1,8-cineol (eucalypt) [54]. Similarly, rosemary chemotypes characterized by verbenone, 1,8-cineol, and camphor, or by verbenone and \(\alpha\)-pinene as major constituents have been identified and associated with geographical origin and climatic conditions of growth [55; 56]. In the current study, a prevalence of verbenone (\(77.59\pm 12.85\)\(\upmu\)g/g), camphor (41.52 \(\pm\) 6.00 \(\upmu\)g/g), and lower concentrations of eucalypt (20.22 \(\pm\) 2.58 \(\upmu\)g/g) were recorded. Thus, it is possible that the rosemary line utilized may be related to a chemotype in which verbenone and camphor are preferably bio-synthesized. Besides verbenone and camphor, considerable amounts of borneol and \(\alpha\)-pinene were observed (11.92 \(\pm\) 2.01 \(\upmu\)g/g and 4.34 \(\pm\) 0.65 \(\upmu\)g/g, respectively). This is expected since they are major components of the rosemary aromatic profile [57; 58]. On the contrary, camphene, a volatile compound typically present in rosemary, could not be identified among all the detected molecules. Among minor compounds, small amounts of alcohols, esters, 2-phenyl ethanol and 2-phenylethyl acetate, were detected (1.00 \(\pm\) 0.22 \(\upmu\)g/g and 0.98 \(\pm\) 0.12 \(\upmu\)g/g, respectively). These compounds could confer floral aromatic notes to the sample, with the former associated with notes of rose. In addition, considerable amounts of ethyl caprylate and ethyl caprate were found (7.66 \(\pm\) 2.34 \(\upmu\)g/g and 12.41 \(\pm\) 1.93 \(\upmu\)g/g, respectively). These compounds are observed in other matrices, such as wine [39]. Finally, volatiles belonging to the aldehyde class, such as hexanal, heptanal, 2-heptanal, and nonanal, were also identified. Aldehydes have been recently reported as components in the volatile profile of rosemary essential oil extracted from _Rosmarinus eriocalyx_[59].
