This study deals with the chemical composition, antimicrobial and antioxidant activities of fruit, flower, leaf and fruit peel from Elaeagnus angustifolia L. growing in Malatya province (Turkey). Identification and quantification of volatile compounds were performed on HS/SPME GC/MS. A total of 53 compounds were identified in all parts of the plant. Metabolic extracts from flower and leaf extracts exhibited the highest antimicrobial activity against Gram positive bacteria with minimum inhibitory concentrations (MIC) ranged from 62.5 to 500 µg/mL. Fruit and flower extracts have the highest antioxidant activity with values ranged from 0.03 to 4.64 for 2.22-azinobis-[3-ethylbenzthiazoline-6-sulphonic acid] (ABTS) assay and from 0.54 to 4.45 µg trolox equivalent antioxidant capacity/g dry weights (DWs) for 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays. Among the plant parts, the lowest and the highest total phenolic contents were found in fruit extracts with the values ranged from 0.12 to 6.39 µg gallic acid equivalents/g DW, respectively.
