The aerial parts of Salvia officinalis were collected in eight gardens in Eastern Lithuania. Essential oils were prepared by the hydrodistillation of air-dried plants and analyzed by GC and GC / MS methods. The dominant constituents were manool (14.4–20.9%, four oils), 1,8-cineole (12.4–17.6%, two samples) and cis-thujone (12.6%, two oils). The second major compound was viridiflorol (11.2–16.5%, four samples), manool (10.3–11.5%, two oils), cis-thujone (11.5%, one oil) and β-caryophyllene (9.0%, one oil). The third position in the sage essential oils was taken by α-humulene (7.3–11.2%, three samples), viridiflorol (10.5%, two oils) and by cis-thujone (9.6%), camphor (9.9%) and manool (8.9%) in other three oils. The S. officinalis essential oil richest in manool (20.9%) was found in Lithuania. The amounts of individual constituents in the oils varied from 2 to 25 times, while the quantities of oxygenated terpenes were close. The sage essential oils included larger quantities of the oxygenated terpenes (52.1–65.4%) than terpene hydrocarbons (18.7–34.1%). The seventy nine identified compounds comprised 89.5–99.3% of the oils.
