Beauty food activities of isolated phenolic compounds from tetragonia tetragonioides

This study examined the beauty food activities of water and ethanol extracts from Tetragonia tetragonioides. Content of phenolic compounds extracted with water and 50% ethanol extracts were 3.29 mg/g and 4.14 mg/g, respectively. 1,1-Diphenyl-2-picrylhydrazyl free radical scavenging activities of water and ethanol extracts were 98.45% and 91.20%, respectively, at 200 μg/mL of phenolics. 2,2′-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical decolorization activity was 97.28% for water extracts and 97.83% for ethanol extracts at 100 μg/mL of phenolics. Antioxidant protection factor (PF) was 1.77 PF for water and ethanol extracts at 200 μg/mL of phenolics. Thiobarbituric acid reactive substances of water and ethanol extracts were 94.77% and 95.64%, respectively, at 100 μg/mL of phenolics. Tyrosinase inhibitory activity, which is related to skin-whitening, was confirmed to be 34.96% for ethanol extracts at 200 μg/mL of phenolics. Elastase inhibitory activity and anti-wrinkle effect of 50% ethanol extracts were 78.9% at 200 μg/mL of phenolics. Collagenase inhibitory activity of ethanol extracts was 61.29% at 200 μg/mL of phenolics. Astringent effect was not detected in water extracts but was 7.82% for 50% ethanol extracts at 200 μg/mL of phenolics. Hyaluronidase inhibitory activity as a measure of anti-inflammation was confirmed to be 81.04% for water extracts at 200 μg/mL of phenolics. Based on these results, Tetragonia tetragonioides extracts can be used as a functional material and functional beauty food with antioxidant effects.
