This study was performed to determine the antioxidative and cytotoxic effects of Elaeagnus multiflora by examining its scavenging effects on the 1,1-diphenyl-2-picryl-hydrazyl(DPPH) radical, the inhibition of lipid peroxidation, and its inhibitory effects on cancer cell proliferation in HeLa cells, MCF-7 cells, and SNU-638 cells by MTT assay. Here, dried samples were extracted in ehtanol at room temperature and fractionated into five different solvent types: hexane, dichloromethane, ethylacetate, butanol, and aqueous partition layers. The hexane(62.92±2.45%) and dichloromethane(65.25±4.74%) fractions of Elaeagnus multiflora’s flesh, and the aqueous(94.65±0.02%) and ethylacetate(93.83±0.02%) fractions of Elaeagnus multiflora’s seeds, inhibited DPPH radical production. The DPPH radical scavenging effects of the flesh and seed were different according to solvent fractions. The inhibition of lipid peroxidation by the flesh and seed extracts were 76.11±3.66 and 69.57±2.27, respectively, for hexane and 67.57±2.43 and 62.09±0.90, respectively, for the dichloromethane fraction. Among the various partition layers of Elaeagnus multiflora’s flesh, hexane and dichloromethane showed the strong cytotoxicities on all the cancer cell lines used in the study. Also all the fractions of Elaeagnus multiflora’s seed exhibited significant effects on the inhibition of cancer cell growth(hexane > dichloromethane > ethylacetate > butanol > aqueous partition layers). These results indicate that the haxane and dichloromethane partition layers of Elaeagnus multiflora’s flesh and seed extracts have possible antioxidative and anticancer capacities. Although further studies are needed, the present work suggests that Elaeagnus multiflora may be an antioxidative and chemopreventive agent.
