Abstract
This study was to investigate characterization as cosmetic substances of extracts of Juj ube using water with in vitro anti-aging and antioxidant activity. Generally, antioxidant activities are dependent on their phenolic constituents. We found that the various jujube extracts dose-dependently increased in vitro antioxidant activities(DPPH radical, ABTS+ radical and Superoxide anion radical scavenging activity). DPPH, ABTS+ and Superoxide anion radical scavenging activity of jujube ethylacetate fraction at concentration of 1,000 μg/mL were 84.5%, 78.5% and 54.9% respectively. In vitro elastase and collagenase inhib ition effects of NN-L at concentration of 1,000 μg/mL was 42.8% and 55.3% respectivel y.All the tested extracts DPPH and ABTS free radical scavenging activity was depend o n their concentration. Especially the ethylacetate fractions presented higher inhibitory eff ect on elastase (65.2% at 10000 μg/mL). so that it showed in vitro anti-wrinkle activity. Finally, the jujube ethyl acetate fractions showed Astringent activity. These results sugg est that the jujube extracts can be used for cosmetic industry
