* Due to a coelution of limonene and eucalyptol, they are presented as a sum. β-phellandrene was not detected in the studied samples, but its traces might have coeluted with limonene and eucalyptol. ** Due to a coelution of hexyl butanoate and 2,6-dimethyl-3,7-octadiene-2,6-diol, they are presented as a sum. Un—undetected, nr—not regulated, c—coelution, LA—L. angustifolia, LL—L. latifolia (spike).
