Abstract: The decanted and recovered (hydrophilic fraction) essential oils of Salvia sclarea obtained from a field distillation unit and Clevenger apparatus distilled essential oil were analyzed by GC and GC-MS. A total of 20 components representing 96.45 %–99.53 % of the oils were identified. The major components of the oils were linalool (27.08 %-62.51 %), linalyl acetate (nil–43.01 %), α-terpineol (2.12 %–20.58 %), β-myrcene (2.03 %–7.29 %), geraniol (0.74 %–4.84 %), (E)-β-ocimene (1.19 %–4.83 %) and geranyl acetate (0.36 %–3.11 %). The oxygenated monoterpenes were found to be higher in the recovered oil (90.28 %) followed by Clevenger distilled oil (87.13 %) and decanted oil (80.39 %). Monoterpene and sesquiterpene hydrocarbons were found to be higher in the decanted oil (17.38 % and 1.45 %, respectively) compared with Clevenger oil (11.38 % and 0.64 %, respectively) and recovered oil (6.06 % and nil, respectively). One of the major components of the decanted oil, linalyl acetate, was not present in the recovered oil obtained from the field distillation unit.
