Abstract

Many of crude products from medicinal plants, becaused of essential oils used in medical. But in most of crude products, essential oils seprated and used as a medicine. The purpose of this study was evalution of essential oils extracted by hydrodistellation method from Salvia officinalis L. and effected on four bacteries (g+) and (g -) consist: E.coli
(g-), Shigella sonnei (g), Bacillus anthracis (g+) and Bacillus cereus (g+), by using well diffusion  method and chemical constituents of essential oils analyzed and determined by GC and GC/MS. Main compounds consist: pinene (5.5%), borneol (9.4%), humulene (8.4%) and globulol (9.3%) .Essential oil effective identified against above mentioned bacterial susspansion by micro organism 10 ⁸ Colony Forming Unit / ml (cfu/ml) until is studied bacteriocide amount.
Bacteriocide activity of Salvia officinalis L. shoot flowers essential oil observed later of 24-48 h zones of growth inhibition respectiviely Bacilluscereus, 40 mm,Bacillus anthracis, 25 mm,Shigella sonnei24 mm, E. coli20 mm.
