This study was conducted to investigate the physicochemical characteristics and biological activities of water and 30%, 50%, 70%, 100% ethanol extracts from Artemisia Argyi H. and fermented Artemisia Argyi H. The yield was the highest in the 30% ethanol extract with Argyi H. at 29.74%. Total phenol and flavonoid contents were the highest in 70% ethanol extract with Argyi H. at 72.25 mg/g and 33.34 mg/g, respectively. The antioxidant activities of all extracts were significantly increased in a dose dependent manner. The 70% ethanol extract from Argyi H. show the highest level of DPPH, ABTS radical scavenging activity and bleaching inhibition activity in -carotene linoleic acid system. Tyrosinase inhibition activity was also higher in the 70% ethanol extract, and the lowest in the 100% ethanol extract with Argyi H. at 50.01% and 11.44% at concentration, respectively. At concentration, the xanthin oxidase inhibition activity of water extract was more than 60%, and it was higher than the extracts. These results suggest that the 70% ethanol extract of Artemisia Argyi H. has a high rate of biological activities and can be useful to develop functional food ingredients. |
