Scutellaria orientalis L. subsp. bicolor (Hochst.) Edmondson EKSTRAKTLARININ ANTYRADYKAL KAPASYTELERYNYN BELYRLENMESY

Öz

Bu çaly?mada, 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 çe?itli antiradikal yöntemler tarafyndan de?erlendirildi. Bu çe?itli antiradikal aktiviteler bütillendirilmi? hidroksianisol (BHA), bütillendirilmi? hidroksitoluen (BHT) ve α-tokoferol gibi standart antioksidanlarla kar?yla?tyryldy. Scutellaria orientalis' in ekstreleri kuvvetli antioksidan aktivite gösterdi. Mevcut çaly?mada alynan sonuçlar Scutellaria orientalis' in do?al antioksidanlaryn potansiyel bir kayna?y oldu?unu gösterdi.

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

Öz

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 α-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.
