Chemical Characterization of Essential Oil of Local Endemic Lamium Bilgilii Celep (Lamiaceae)

Abstract

In this study, the chemical constitution of the essential oil of Lamium bilgilii Celep, a local endemic species of Turkey, was studied by GC-MS for the first time. 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.
