We investigated the protective effects of antioxidant fractions from a 70% ethanolic extract of Hizikia fusiformis in human dermal fibroblasts (HDFs). Powdered H. fusiformis was extracted with 70% ethanol and then partitioned into three fractions according to polarity using n-hexane (HFH), chloroform (HFC), and ethyl acetate (HFEA). Anti- oxidant activity was observed in HFEA at 0.66 mg/mL based on the half maximal inhibitory concentration (IC

50

) of 1,1-diphenyl-2-picrylhydrazyl (DPPH), and at 0.24 mg/mL based on alkyl radical scavenging. The protective effects of the HFEA antioxidant fraction against 2,2-azobis-(2-amidinopropane) dihydrochloride (AAPH)-damaged HDFs and the expression of Type I procollagen in HDFs were examined. HFEA caused the proliferation of HDFs with and without AAPH treatment and protected against AAPH damage to HDFs in a dose-dependent manner (50-200 µg/mL). This implies that the antioxidant properties of the fractions depended on their proliferative and protective effects. The HFEA antioxidant fraction had significant effects and caused the dose-dependent expression of Type I procollagen, an important anti-wrinkle protein, in HDFs. In conclusion, antioxidant substances in H. fusiformis were found in the ethyl acetate fraction, and the resulting HFEA may have cosmetic applications.
