Antioxidant Activity of Aralia elata Seeds Fractions

초록

Aralia elata is the edible vegetable and has been used for medicinal purposes. The present study investigated the in vitro antioxidant potential of dichloromethane (CH2Cl2), ethyl acetate (EtOAc), n-butanol (n-BuOH) and water (H2O) fraction of 70% methanolic (MeOH) extract of A. elata seeds using different antioxidant tests, such as total phenolic content, 1,1-diphenyl-2-pricylhydrazyl (DPPH) radical-scavenging assay, hydroxyl-radical (･OH) scavenging assay, reducing power assay, metal-chelating activity and lipid peroxidant assay. Among these fractions, EtOAc fraction exhibited higher antioxidant potency than other fractions in DPPH free radical-scavenging, hydroxyl radical-scavenging activity, reducing power assay and lipid peroxidant assay. It was concluded that the A. elata seeds fractions obtained from 70% MeOH extract are highly suitable for medical application due to their efficient antioxidant properties.
