The main characterized constituents were β ‐caryophyllene (8.5 and 35.2%), terpinolene (18.4 and 6.3%), (E)‐ocimenone (12.6 and 9.8%), (Z)‐ β ‐ocimene (10.4 and 13.7%), piperitenone (10.4 and 2.6%), (Z)‐ocimenone (5.5 and 7.7%) and limonene (6.2 and 2.5%) in leaf and stem and flower oils respectively.
