Antioxidant Activities of Native Gwangyang Rubus coreanus Miq.

摘要: In other to promote the utilization of native Gwangyang Rubus coreanus Miq. as an antioxidant material in functional food, its general composition, free sugars, vitamin C, E, and anthocyanin content were examined. Free sugars mainly 2.83±0.01% glucose 3.49±0.17% fructose. Native included higher C (0.04 g/100 g) E contents than Anthocyanin was detected be 2.41 g. Two extracts from Miq., hot water extract (RCW) 80% ethanol (RCE), prepared by reflux, filter, freeze-dry. The phenolic compound levels RCW RCE 5.99% 6.20%, respectively. DPPH- ABTS-radical scavenging activities, lipid peroxidation formation inhibitory activity, exhibited relatively high activities when compared (89.29% vs. 65.04%, 47.65% 30.22%, 23.27% 3.6%, respectively). Based upon these results, it is suggested that possesses potentials for radical anti-lipid activities.
