Objectives : The purpose of this study was to investigate antiaging and antioxidant effects on cultured human skin fibroblast with supercritical fluid extracts of Dendropanax morbifera, Corni fructus and Lycii Fructus. Methods : Supercritical fluid extraction (SFE) technique was applied to extract from three medicinal plants including stem of Dendropanax morbifera, Corni fructus and Lycii Fructus. Antioxidant activity of extract was evaluated by two different assays as 2,2-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and super oxide dismutase (SOD) like activities. These extracts were tested for cell viability on HS68 skin fibroblast by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. We investigated the effects of Ultraviolet-B irradiation on cytotoxicity, type 1 collagen, elastin level and oxidative damage in cultured human skin fibroblast (HS68). Recently, many studies have reported that elastin is also involved in inhibiting or repairing wrinkle formation, although collagen is a major factor in the skin wrinkle formation. Results : The extracts obtained dose-dependently increased the scavenging activity on DPPH radical scavenging activity and SOD like activity. The supercritical fluid extracts of complex herbal medicine showed low cytotoxicity as more than 100% cell viability in 100ppm/ml concentration. HS68 fibroblasts were survived 70% at $120mJ/cm^2$ UVB irradiation and treated tumor necrosis factor (TNF)-alpha. The levels of aging factors and cytotoxicity were decreased by supercritical fluid extract of complex herbal medicine. Conclusions : These results suggest that supercritical fluid extracts may have value as the potential antioxidant and antiaging medicinal plant.
