SCUTELLARİA ORİENTALİS L. SUBSP. BİCOLOR (HOCHST.) EDMONDSON EKSTRAKTLARININ ANTİRADİKAL KAPASİTELERİNİN BELİRLENMESİ

Semra TÜRKOĞLU 1

Bu çalışmada, Scutellaria orientalis L. subsp. bicolor (Hochst.) Edmondson’ in su ve etanol ekstrelerinin antiradikal aktivitesi ABTS• (2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) radikal temizleme kapasitesi and DPPH• (2,2-diphenyl-1-picrylhydrazyl) radikal temizleme kapasitesi gibi çeşitli antiradikal yöntemler tarafından değerlendirildi. Bu çeşitli antiradikal aktiviteler bütillendirilmiş hidroksianisol (BHA), bütillendirilmiş hidroksitoluen (BHT) ve ?-tokoferol gibi standart antioksidanlarla karşılaştırıldı. Scutellaria orientalis’ in ekstreleri kuvvetli antioksidan aktivite gösterdi. Mevcut çalışmada alınan sonuçlar Scutellaria orientalis’ in doğal antioksidanların potansiyel bir kaynağı olduğunu gösterdi.

DETERMINATION OF ANTIRADICAL CAPACITY OF EXTRACTS SCUTELLARIA ORIENTALIS L. SUBSP. BICOLOR (HOCHST.) EDMONDSON

Semra TÜRKOĞLU 1

In this study, the antiradikal activity of water and ethanol extracts of Scutellaria orientalis L. subsp. bicolor (Hochst.) Edmondson was evaluated by various antiradical assay, ABTS• (2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) radical scavenging capacity and DPPH• (2,2-diphenyl-1-picrylhydrazyl) radical scavenging capacity. Those various antiradical activities were compared to standard antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and ?-tocopherol. The extracts of Scutellaria orientalis showed strong antioxidant activity. The results obtained in the present study indicated that Scutellaria orientalis is a potential source of natural antioxidant.
