This study was conducted to evaluate physiological activity of flower extract of peony (Paeonia lactiflora Pall.) by hydrolysis and to use it as a valuable cosmetic ingredients. Four cultivar of peony flowers were extracted, and the highest active ingredient contents was selected, and that cultivar was used for hydrolyzing. The results showed that high concentration of hydrochloric acid (HCl) hydrolyzed, and biological hydrolysis using enzymes had no activity. The deglycosylation of peonidin 3,5-diglucoside occurred by hydrolysis. The hydrolysate contains 63.3 ppm of peonidin, a red-colored anthocyanin compound. The antioxidant activity of hydrolysate was compared with extract. The results showed the strong antioxidant activity in hydrolysate (96%) than extract (82%). In addition, hydrolysate of peony flower showed higher inhibitory activity of NO release than extract. UVA assay using fibroblast cell (CCD-986Sk) showed that hydrolysate increased cell viability than extract under UVA exposure. Based on these results, we anticipate that hydrolysate of peony flower can be used a valuable cosmetic ingredient.
