Germacrene D was the main component found in the hydrodistilled oils from wild-grown (22.8%) and cultivated plants (16.9%), respectively, followed by 2-methyloctane (10.8–17.8%), β-caryophyllene (6.6–10.3%), α-pinene (5.2–10.1%) and bicyclogermacrene (4.1–4.8%). Fourteen of the constituents characterized in the oils of wild-grown plants were not detected in the oils of cultivated plants.
