Abstract The essential oil of overground parts of wild Glechoma hederacea L. collected at full flowering in seven localities of Eastern Lithuania were analyzed by GC and GC/MS. More than half of the oils were rich in sesquiterpene hydrocarbons (56.5â67.9%). The most predominant compound was germacrene D (14.1â20.7%). The other main constituents were Î³-elemene (9.0â16.0%), Î²-elemene (8.7â12.9%), phytols (2.8â15.6%), (Z)-Î²-ocimene (2.2â8.5%), 1,8-cineole (92.2â5.4%), Î²-ylangene (2.7â4.1%) and germacrene B (2.2â3.9%). Forty-three identified compounds made up 89.1â96.2%.
