ABSTRACT
In this study, we investigated the potential of 70% ethanol extracts from wild edible plants (Pueraria lobata sprout, Rosa multiflora sprout, Artemisia princeps leaf, Diospyros kaki leaf, Morus alba leaf, Robinia pseudoacacia flower, Inula britannica var. japonica flower), as natural antioxidants. The antioxidant contents and activities of extracts were examined using various methods. The measurements of total polyphenol content revealed that Rosa multiflora sprout extract had the highest value and total flavonoid content showed that Diospyros kaki leaf extract had the highest value. Antioxidant activities were the highest in Rosa multiflora sprout for DPPH (IC50 232.52 μg/mL), ABTS+ (IC50 470.10 μg/mL), superoxide− (IC50 431.88 μg/mL), nitrite (IC50 363.38 μg/mL) scavenging activity, and reducing power (2.47 O.D.). These results suggest that the ethanolic extract of Rosa multiflora sprout is a potential source of natural antioxidants.
