Among PGRs Jasmonic (JA) and salicylic acid (SA) have many applications in medicinal plants. Experimental: This study was carried out to survey the effect of spraying of various concentrations JA and SA on S. officinalis L. in field experiment of Hormozgan, South Iran at 2010-2011. A pot experiment was conducted in a CRD with ten treatments with three replicates. The treatments including I: distilled water (control), II: distilled water and solution (acetone), III-VI: SA in different concentrations (1, 10, 20 and 40 mol/l, VII-X: JA in various concentrations including 50, 100, 200 and 400 µM. The leaves were harvested at before flowering and, the essential oil extracted by Clevenger approach then the compounds were characterized using Gas Chromatography–Mass Spectrometry (GC-MS). Results & Discussion: Results showed that various concentrations of foliar application of JA and SA lead to decrease or increasing of some secondary metabolites in essential oil of S. officinalis L. Compounds such as a-pinene, camphene, b-pinene, 1,8-cineole, cis-thujane, trans-thujane, borneol, bornyl acetate and camphor were affected from JA and SA treatments.
