Antioxidant Potential of Grass Pea Seeds from European Countries
AbstractPhenolic compounds were extracted from seeds of 30 varieties of grass pea (Lathyrus sativus) into 80% (v/v) methanol. The total phenolics compounds content of the extracts and their antioxidant activity were determined using Folin-Ciocalteu’s phenol reagent and 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric-reducing antioxidant power (FRAP) methods, respectively. Total phenolic contents ranged from 1.88 to 7.12 mg/g extract and 20.3 to 70.3 mg/100 g seeds. The extracts and seeds were characterized using Trolox equivalent antioxidant capacity values of 0.015–0.037 mmol Trolox/g extract and 0.158–0.372 mmol Trolox/100 g seeds, and FRAP values of 0.045–0.120 mmol Fe2+/g extract and 0.487–1.189 Fe2+/100 g seeds. The total phenolics content of grass pea extract was correlated with the results of the ABTS (r = 0.881) and FRAP (r = 0.781) assays. The same correlation was observed between the results of both assays (r = 0.842). Two derivatives of p-coumaric acid were the dominant phenolic compounds of the Derek cultivar of grass pea.
