Abstract

The phenolic contents which were extracted with water and 70% ethanol from O. undulatifolius were 7.7, 10.1 mg/g, respectively. The 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity of water and ethanol extracts were 78, 82% at 50 μg/mL phenolics, respectively. The 2,2′-Azinobis-(3-ethyl-benzothiazoline-6-sulfonic acid) radical cation decolorization activity were 92, 76% at 100 μg/mL phenolics. Antioxidant protection factor in water and ethanol extracts at 200 μg/mL phenolics were 1.51 and 2.08 PF, respectively. Thiobarbituric acid reactive substance were 84% in water extracts and 99% in ethanol extracts at 50 μg/mL phenolics, respectively. The inhibition activity on α-Glucosidase was 44% in ethanol extracts at 200 μg/mL phenolics. The inhibition activity on α-amylase was 37-88% in water extracts at 50-200 μg/mL phenolics. The tyrosinase inhibition activity as whitening effect were 82% in ethanol extracts. The elastase inhibition activity were 4, 61% in water and ethanol extracts, respectively. The collagenase inhibition activity of anti-wrinkle effect showed an excellent wrinkle improvement effect as 39% in water extracts and 67% in ethanol extracts at 200 μg/mL phenolics, respectively. The hyaluronidase inhibition activity as anti-inflammation effect of ethanol extracts was confirmed to 46% of inhibition at 200 μg/mL phenolic. The astringent effect of water and ethanol extracts was confirmed to 13, 32% of effect at 200 μg/ mL phenolic, respectively.
