COSMIN ILIE, IONUT GOLET, MIHAELA CRACIUNESCU, ELENA HOGEA, ROXANA POPESCU, FLORIN GEORGE HORHAT CHEMICAL COMPOSITION AND ANTIMICROBIAL ACTIVITY OF ESSENTIAL OIL OF WESTERN ROMANIAN SALVIA OFFICINALIS
This study has focused on determining the chemical composition and antimicrobial properties of the essential oil (EO) of S. officinalis grown in Romania. The oil was isolated by steam distillation in 1.9% yield and then analyzed by GC-MS. The major compounds were camphor (23.76%), alpha-thujone (14.60%) and alpha-humulene (10.13%). The disk diffusion method was used to evaluate the antimicrobial properties of sage EO. The EO exhibited antibacterial activity against all tested strains, especially against Staphylococcus aureus and Klebsiella pneumoniae. The results obtained suggest that the analyzed oil can represent a new cheap and natural source of antiseptic compounds with potential applications against food-borne pathogens.
