Abstract
Biological activity and making use of sage,s essential oil in different industries depends on chemical composition of essential oil, which is impresionable by different factors.
In order to study the quality and quantity of essential oil along growth periods, the plant samples were gathered and essential oil were isolated by steam distillation method. Volatile parts was analysed by GC\MS instrument.
This study revealed that quality and quantity of chemical composition is different based on parts of plant; α-thujone and β-thujone as two important compound were the lowest in the leaves of sage at flowering stage ( 1.2 % , 3%).
The present study showed that quantity of Champhor (2.9%), Cineole (2%), α-thujone (6.4%), and β-thujone (1.6%) in essential oil of aerial parts of plant are lower than the level of international stansard.
