Methanol and water extracts of Salvia virgata Jacq. aerial parts were examined for its phenolic contents and antioxidant activities. Both extracts were investigated for their total phenolic contents, total flavonoids and flavonols, qualitative-quantitative compositions (by HPLC-PDA analysis). Free radical scavenging activities (using DPPH● and ABTS●+), iron(II) chelation activity and also the peroxidation level was determined by TBA method. The antioxidant activity of extracts were given as IC50 values and compared with standards; butylated hydoxyanisole, butylated hydoxytoluene, rosmarinic acid, ascorbic acid, and gallic acid. Methanol extract was found to be active for DPPH● radical scavenging activity where as water extract was more active for ABTS●+ radical scavenging. The methanol extract enriched in phenolic compound and rosmarinic acid as the main component in both extracts has been identified

Keywords: Salvia virgata, Antioxidant Activity, HPLC

Salvia virgata Jacq.’ın toprak üstü kısımlarının metanol ve su ekstresinin fenolik içeriği ve antioksidan özellikleri belirlenmiştir. Her iki ekstrenin de toplam fenolik, toplam flavonoit ve flavonol içeriği, kalitatif-kantitatif kompozisyonları (YBSK ile), serbest radikal süpürücü aktiviteleri (DPPH● ve ABTS●+), demir(II) ile şelat oluşumu ve TBA yöntemi ile peroksidasyon seviyeleri incelenmiştir. IC50 değeri olarak verilen antioksidan aktiviteler butil hidroksianisol, butil hidroksitoluen, rozmarinik asit, askorbik asit ve gallik asit standartları ile karşılaştırılmıştır. Metanol ekstresi DPPH● radikalini süpürücü etkide aktif bulunurken, su ekstresi ABTS●+ radikalini süpürücü etkide aktif bulunmuştur. Metanol ektresinin fenolik bileşiminin daha zengin olduğu ve her iki ekstrede de rozmarinik asitin ana bileşen olduğu tespit edilmiştir.
