Radical Scavenging Activity of Some Lathyrus Taxa Distributed in Burdur-Isparta Regio

Abstract

Radical scavenging activity of the extracts of Lathyrus aphaca L. var. pseudoaphaca (Boiss.) Davis, L. aureus (Stev.) Brandza, L. cicera L., L. sphaericus Retz., L. digitatus (Bieb.) Fiori in Fiori & Paol. and L. setifolius L. taxa distributed in Burdur-Isparta regio was determined. Methanol extracts of air dried aerial parts and the seeds of the plants were dissolved in water and chlorophylls and lipophilic compounds were removed from the aqueous extracts. 2,2-diphenyl-1-picryl hydrazyl, superoxide and nitric oxide radical scavenging activity of aqueous and methanol extracts of the plants were tested. Gallic acid equivalent total phenolic contents of the plant extracts were also detected using Folin-Ciocalteu reagent. According to the 2,2-diphenyl-1-picryl hydrazyl radical scavenging activity test, the highest antioxidant activity was found in aerial parts of L. aphaca var. pseudoaphaca and highest total phenolic content was found as gallic acid equivalent in L. sphaericus seed extracts.
