Screening Study on Antioxidant Activity of Plants Grown Wildly in Mongolia

In this study, 50% ethanol extract prepared from dry leaves of eight plants grown wildly in Mongolia were characterized for DPPH radical scavenging activity, ABTS radical cation scavenging activity, superoxide anion scavenging activity, ferric reducing power, iron chelating ability, and content of total phenol, flavonoid, and flavanol in order to find good sources of natural antioxidant from plant kingdom. Correlation coefficients between antioxidant parameters and contents of polyphenolic compounds were also calculated. Among them, leaves of Vaccinium vitis-idaeae, Paeonia anomala, Rosa acicularis, and Hippophae rhamnoides were rich in polyphenolics and exerted strong scavenging activity against DPPH radical, ABTS radical cation, and superoxide anion and reducing power.
