چکیده :

Phenolic compounds are one of the main secondary metabolites of medicinal plant Salvia officinalise. Due to potential use of them as source of natural antioxidants, increasing the phenolic content of medicinal plants have been investigated in many researches. Use of elicitors as signals triggering the secondary metabolites production is one of the most effective strategy for improving the bioactive secondary metabolites content. In this study, the effects of applied foliar spray of abiotic elicitors, Salicylic acid (SA) and silver nitrate (AgNO3) on phenolic compounds were studied in a CRD design with three replications in greenhouse. Results shown a significant increase for phenolic content under the influence of SA and AgNO3 elicitors. The AgNO3 effect on phenolic content was significantly more than SA for all used concentration. It seems that by key role of antioxidant defense system throught phenolic compounds in the defense mechanisms followed induced the increase of secondary metabolites content of S. officinalise.
