This study was performed to determine antioxidative activity of solvent extracts from medicinal plant. As the result, methanol extract from Saurus chinensis Bail and Glycine soya exhibited superior free radical activity as well as reducing power. In particular, methanol extract from Saurus chinensis Bail showed high free radical activity with 130.08${mu}g/mL$ as $IC_{50}$ value and strong reducing power at concentration of $400{mu}g/mL$.
