Essential sage oil (ESO) was isolated from dry leaves by steam distillation with Neo-Clevenger apparatus. The chemical analysis of the ESO consisted in the assessment of the total polyphenolic content (Folin-Ciocâlteu method) and of the radical scavenging activity with DPPH. The antioxidant activity was measured using two standard compounds: gallic acid and ascorbic acid. Phenolic content of essential oil of S. officinalis was significant (15.465 mg GAE/g oil) and antioxidant activity was high. Antibacterial activity of essential sage oil was evaluated against Gram positive and Gram-negative bacterial strains isolated from clinical specimens. The sage oil showed significant but variable antibacterial activity with inhibition zones ranging from 4 mm to 9.5.mm. The effect was stronger on Gram positive (Enterococcus, Staplylococcus) than Gram negative bacteria (Escherichia sp, Proteus sp, Klebsiella sp).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
