Ten phenolic compounds were isolated from a butanol fraction of sage extracts. Their structures were determined by spectral methods (NMR, MS, IR). Among them, a novel compound, 4-hydroxyacetophenone-4- O -β- d -apiofuranosyl-(1→6)- O -β- d -glucopyranoside, was identified. Two test systems, DPPH free radical scavenging activity and radical cation ABTS • + scavenging activity, were used to evaluate their antioxidant activity. The most active compounds were found to be rosmarinic acid and luteolin-7- O -β-glucopyranoside. Keywords: Sage; Salvia officinalis; phenolic compounds; antioxidant activity
