Kimchi is well known as a traditional Korean food containing various antioxidative compounds and it has been demonstrated that dietary kimchi inhibit the tissue oxidation and aging in many related studies. Ultraviolet B (UVB) radiation is the most potent among the many related factor to skin photo-aging. This experiment is designed to elucidate the inhibitory effect of solvent fractionation of various kimchi on UVB induced oxidation and erythema formation. Among solvent fractions, phenol content mostly existed in dichloromethane / ethylacetate fraction of buchu kimchi, dichloromethane fraction of Korean cabbage kimchi and ethylacetate / dichloromethane fraction of mustard leaf kimchi. Free radical scavenging activities were higher in dichloromethane and ethylacetate fraction from buchu kimchi, dichloromethane fraction from Korean cabbage kimchi, and ethylacetate fraction from mustard leaf kimchi. When the damage of photo-oxidation by UVB irradiation was tested in the presence of solvent fractions of kimchi, dichloromethane / ethylacetate fraction of buchu kimchi, ethylacetate fraction from Korean cabbage and from mustard leaf kimchi showed the higher protective activities than others. The erythema formations which were induced by UVB irradiation were decreased in solvent fractions of kimchi that hate higher antioxidant activities. In conclusion, kimchi solvent fractions having antioxidant compounds mostly inhibited photo-oxidation and erythema formation by UV-irradiation, therefore kimchi consumption can retard skin aging due to the presence of antioxidative compounds.
