| Main components of the essential oil from the leaves (0.1-0.3%) were (Z,Z)-octa-9,12-dien-1-ol (6.1-28.0%), (Z,Z,Z)-octa-9,12,15-trien-1-ol (9.8-24.7%), (E)-phytol (3.1-11.6%), E-β-caryophyllene (3.6-12.8%), and germacrene D (4.2-9.1%). The characteristic tar-like aroma may be due to the occurence of several hydrocarbons (4.3-9.1%) including 2-methylpentane (0.3-1.5%), heptane (0.1-0.5%), C-6/C-8/C-9/C-21/C-23/C-25/C-27/C-28 and squalene together with phenolics (4.3-7.8%) like phenol, guaiacol, methyl chavicol (0.2-1.0%), 4-vinylguaiacol (0.4-1.1%) e.g. as well as sulfur compounds like methional (0.1-0.2%), furfuryl methyl sulfide (trace-0.1%) and mint sulfide (trace-0.1%). Maltol (trace-0.1%), indole (trace), and β-ionone (trace-0.1%) were also present. \\ | Main components of the essential oil from the leaves (0.1-0.3%) were (Z,Z)-octa-9,12-dien-1-ol (6.1-28.0%), (Z,Z,Z)-octa-9,12,15-trien-1-ol (9.8-24.7%), (E)-phytol (3.1-11.6%), E-β-caryophyllene (3.6-12.8%), and germacrene D (4.2-9.1%).
