Abstract
The hydrodistilled essential oil of fresh aerial parts of Salvia officinalis, collected at Batna (Eastern Algerian) was analyzed by GC and GC/MS. 35 components representing 98.39 % of the essential oil were detected with α-thujone (24.52%) ,1,8- cineole (15.92%), camphor (16.86%) , β-thujone (6.50%) and veridiflorol (6.35%), as the major components. The antibacterial activity of the essential oil was tested against eighth gram-positive and gramnegative bacteria by the use of the disc diffusion method. The antioxidant activity was also investigated by the use of β-carotene bleaching method.
