Phytochemical essential oil analysis of Salvia leriifolia Benth. from different stages and habitats (natural and greenhouse condition)

Salvia leriifolia Bench.is belongs to Laminaceae family, which as antioxidant, antibacterial, sedative and anti diabetes properties. In the present study, the quality and quantity of plant essential oil in different various growth stages were evaluated. The leaves of plant were collected during vegetative, blooming and seed maturity from natural habitat (Abkhovan Sabzevar, Khorasan Razavi province) and greenhouse in spring 2012. Essential oils were obtained by hydro distillation method (Clevenger apparatus) and analyzed by GC and GC / MS. The results were showed that in blooming stage especially in natural habitat, the plant had the highest essential oil content (1.04%) in which the camphor (23.85%), β-pinene (9.8%), 1,8-cineol (8.04%) and α-pinene (6.87%) were the most abundant essential oil constituents. Furthermore, in both regions camphor, β-pinene and α-pinene were the most constituents of plant oils, but in seed maturity stage the oil content (0.65%) was decreased and the camphor wasnt recorded, while in other stages the camphor were the highest content in both regions.
