The essential oil of Salvia Officinalis, an endemic medicinal plant from Morocco, have been studied us ing gas chromatography (GC) and GC-mass spectrometry (GC-MS ). 96.3% of the components are detected. and the ma jor components were ,l’ α -thujone (22.2%), le 1,8-cinéole (18.4%), le trans-pinocarveol (9.4%), le β -thujone (8.4%) le β -pinène (8.2), le globulol (5.9% ) , le α -Humulene (3.7 %) et le trans-caryophyllène (2 .6%).The antifungal activity of the essential oil was evalua ted in vitro by poison food (PF) technique and the volatile activity assay (VA) against three phytopathogenic causing th e deterioration for apple such as Botrytis cinerea, Penicilliumexpansum and Rhizopusstolonifer. The PF technique demonstrated significant inhibition of the mycelial growth of all strains (p < 0.05), with the complete inhibition of P. expansum at MIC = 2 μ L/mL. Simila rly, the VA assay showed that the essential oil strongly inhibi ts all three fungi. The complete inhibition of the mycelial growth of both P.expansum and R.stolonifer, was observed resp ectively at MIQ = 80 μ L/disc and 160μ L/disc. The ov erall results suggest that S.Officinalis essential oil ha ve a potential as antifungal preservatives for the control of postharvest diseases of apple.
