The purpose of this study was to research the biological activity of ethanol extract from Smilax china L. which is a vine shrub belonging to the lily family. For antiwrinkle effects, elastase inhibition effect of ethanol and water extracts from S. china L. showed 41.1% and 16.3% at 1,000 μg/ml concentration. The collagenase inhibition effect of ethanol and water extracts from S. china L. showed more than 96.6% and 60.0% at 1,000 μg/ml concentration. As a result of having fibroblast measured cell viability on fibroblast cell of ethanol extract from S. china L., it showed 71.7% with cell viability at 100 μg/ml concentration. At 50 μg/ml concentration, the procollagen biosynthesis effect of ethanol extract from S. china L. was 139.86%. At the same concentration, the matrix metalloprotease (MMP)-1 inhibition effect of the ethanol extract was 74.9%. According to the results of Western blot of ethanol extract from S. china L., the expression of the MMP-1 protein was decreased by 35% at 50 μg/ml concentration. Reverse transcription-polymerase chain reaction (PCR) of ethanol extract from S. china L. showed that the expression of MMP-1 mRNA was decreased by 45% at 50 μg/ml concentration. The findings suggest that 70% ethanol extract from S. china L. (SC) has great potential as a cosmeceutical ingredient with antiwrinkle effects.
