Chemical Composition of Essential Oil and Antioxidant Activity of, an Endemic Species from Iran

Chemical composition of essential oil from, leaves, stems and flowers of Salvia sclareopsis in flowering stage were determinated by using GC and GC/MS. Result showed that the main compounds of the leaves were viridiflorol, (23.47 %), humulene (18.37 %) and a-muurolene (8.37 %). Octadecane (20.57 %), caryophyllene oxide (7.68 %) and geranyl acetate (3.87 %) were major constituents in the stems also linalool (27.79 %), linalool oxide (9.41 %), and hexyl 2-methyl butyrate (5.16 %) were main compounds of the flowers. The antioxidant properties were measured by DPPH and beta-carotene linoleaic acid tests. The result of DPPH assays showed that leaves are higher antioxidant campared with other organs, while in -carotene linoleaic acid assay all organs have same antioxidant acivity.
