+The most abundant compounds identified in the essential oils from G.verum fresh leaves were 2-methylbenzaldehyde (26.3%), (Z)-3-hexenol (17.3%), 4-methylbenzaldehyde (7.3%), phenylacetaldehyde (5.1%), benzyl alcohol (4.3%), (3Z)-hexenyl acetate (3.4%), eugenol (1.1%), and benzaldehyde (1.0%). Minor components were e.g. alcohols like hexanol, 1-octen-3-ol and geraniol; aldehydes like hexanal, nonanal, decanal, beta cyclocitral, 2,4-decadienal and dodecanal; aromatics like methyl salicylate, alpha terpineol, indole, and p-vinyl guaiacol. \\
