Özet:

Methanolic extracts of 39 different population of three species of Salvia (Salvia fruticosa Mill. 20 sample, Salvia pomifera Mill. 4 sample and Salvia tomentosa Mill. 15 sample) were analyzed for their antioxidant properties. Samples were collected from different natural ecological areas in Marmara Region in Turkey. The antioxidant activity (AA) was investigated with the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method and expressed as trolox equivalents (TE). The amount of total phenolics was determined by using Folin–Ciocalteu method and flavonoid contents in the extracts were determined by a colorimetric method. The AA values of the spices ranged from 287. 57 to 450.51 µmol trolox equivalent (TE) / 100 g dry weight (DW). The total phenolic and flavonoid content ranged from 488.07 to 1654.89 mg of gallic acid equivalents (GAE) / 100 g DW and 664.03 to 3693.20 mg of catechin equivalents (CE) / 100 g DW respectively
