This study analyzed the composition and contents of acacia(Robinia pseudoacacia) flower extracts, free amino acid of water and methanol extracts and polyphenol compound. Then, the physiological activities of some skin care cosmetic examined. The study results found the followings: The free amino acid of acacia flower hot water extracts was 36.96 mg/g in total, and a total 16 types of free amino acids were isolated. In methanol extract, however, a total of 13.41 mg/g were found in 13 different types. In terms of polyphenol contents, methanol extract was slightly higher than hot-water extract. Regarding the composition of polyphenol compound, 8 different types of phenolic acids and two types of flavonoids were found in hot-water and methanol extracts. The DPPH radical scavenging activity was increased in proportion to the concentration, and the inhibitory activity of tyrosinase in the hot-water and methanol extracts of acacia flower was increased in proportion to the concentration. The ell growth according to human skin cell line, HaCaT was very low cell growth inhibited in an concentration-dependent. The inhibitory activity of elastase and collagenase in the hot-water extract and methanol extracts increased in a concentration-dependent manner. The said results show that because free amino acid and polyphenol contents are rich in the hot-water extract of acacia and methanol extract, they could be very useful as cell growth activating factors or natural antioxidants. To use them as cosmetic ingredients, however, there should be further studies on correlations between the enzyme activity in the cell and various cosmetic components. |
