Analysis of Antioxidative Effects of Fruit Extracts of Nandina domestica for the Development of Beauty Materials

This study was carried out to investigate the antioxidative effects of water and ethanol extracts from the fruit of Nandina domestica as part of the development of functional beauty materials. The highest content of polyphenol compound was 115.06 mg/g in the water extract, and the content of flavonoid compounds was the highest as 60.73 mg/g in the ethanol extract. In the measurements of electron donating ability, both extracts revealed high abilities more than 80% at 0.1 mg/mL concentration. The SOD-like activities of water and ethanol extracts showed the highest effect as 42.88% and 45.96% at 1.0 mg/mL concentration, respectively. In the analysis of nitrate scavenging activity, ethanol extract showed the highest activity as 60.92% and 62.70% in the condition of pH 1.2 and pH 3.0 at 1.0 mg/mL concentration, respectively. The xanthine oxidase inhibitory rate of water extract had the highest effect as 96.97% at 1.0 mg/mL concentration. These results verified that water and ethanol extracts from the fruit of N. domestica have a strong antioxidant activity and can be used as an effective antioxidant source for manufactures, medicines and cosmetic stuffs.
