The essential oil was obtained by hydrodistillation method and forty-three compounds were successfully identified representing 98.2% of the oil. Bicyclogermacrene (14.22%) and linalyl acetate (8.33%) and linalool (7.86%) were the most abundant components of the essential oil. L. bilgilii essential oil was rich in sesquiterpenes (35.8%) and oxygenated monoterpenes (26.6%). The results showed that bicyclogermacrene was found, for the first time, as a most abundant component in the Lamium oils.eninfo:eu-repo/semantics/openAccessLamium bilgilii; Lamiaceae; essential oil; bicyclogermacrene; GC-MSArticle751344210.7546/CRABS.2022.01.052-s2.0-85124650652Q3WOS:000754853800005Q4
