In Vitro Antioxidant Activity of Pyrus Boissieriana, Diospyros Lotus, Eryngium Caucasicum and Froriepia Subpinnata

Background and Objectives: Pyrus boissieriana, Diospyros lotus, Eryngium caucasicum, Froriepia subpinnata are native to Northern part of Iran and are widly used in local foods. Diospyros lotus fruits are used in prepration ofjams. Ecaucasicum and Esubpinnata also used 35 wild herbs in local foods. Materials and Methods: In this Experimental study, the antioxidant activity of methanolic extract of Pyrus boissieriana. Diospyros lotus, Eryngium caucasicum, Froriepia subpinnata were determined with 6 invitro assay include DPPH, nitric oxide, 1-120 1 radicals scavenging, linoleic acid, reucing power and iron ion chelating activity. Total phenolic and flavonoid compounds of extract was measured by Folin Ciocalteu and AICI, assays. Results: ICsoin DPPH method was in order: E. caucasicum > F. subpinnata> D. lotus> and P. boissieriana mg mlʹ, respectively. The extracts showed weak nitric oxide-scavenging activity. The E. caucasicum and F. subpinnata extracts were better than others respectively. The F. subpinnata and E. caucasicum had shown better reducing power than other extract that was comparable with Vit C (p
