The aim of this study was to evaluate the physicochemical properties and antioxidant and anti-proliferative activities of different plant parts of Elaeagnus umbellata Thunb. extracted with ethanol (EtOH). EtOH extract of stems presenting the highest content of polyphenols showed the strongest 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity (). The total content of free amino acids decreased in the order of leaves (6,179.12 mg/100 g)> stems (1,211.69 mg/100 g)> fruits EtOH extract (378.88 mg/100 g), and asparagine (1,907.57 mg/100 g), acid (300.17 mg/100 g), and proline (233.48 mg/100 g) were the major free amino acid in leaves, stems, and fruits, respectively. Five phenolic compounds in each extract were measured by using liquid chromatography- tandem mass spectrometry, and gallic acid (98.95 mg/100 g) and (+)-catechin (1,575.99 mg/100 g) were present as major components in leaves and stems, respectively. EtOH extract of leaves showed the highest anti-proliferative activity against HepG2 cells as measured by 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazoliumbromide and lactate dehydrogenase assay but had no effects on Chang liver cells.
