In this study, S. glauca (Bunge) Bunge extract was testified total polyphenol contents, electron donating ability on DPPH, and scavenging ability of superoxide anion radical and hydrogen peroxide. Total polyphenol contents of S. glauca (Bunge) Bunge extract were 7,053.30±915.93 μg GAE/mL. In the fractions, fraction by ethanol was the highest content of 10,973.30±1,000.24 μg GAE/mL.
Fractions of ethyl acetate and water were 2,386.70±166.53 μg GAE/mL, 2,413.30±41.63 μg GAE/mL respectively. It was shown that total content of polyphenol according to solvent was significant relation at p<0.05. In the experiment of the electron donating ability, 70% ethanol extract and methylene chloride fraction were －246.15±24.17%, －254.01± 16.54% respectively. In case of ethyl acetate fraction, it was the highest electron donating ability to DPPH radical, 39.06±0.34%, and then water fraction of 36.71±5.55%, ethanol fraction of 29.77±2.57%, gradually. Electron donating abilities revealed significant difference (p<0.05) between the solvents. The superoxide radical scavenging ability of standard material was 0.029±0.0011; 70% ethanol extract of 0.022±0.00052, methylene chloride fraction of 0.027±0.00031, ethyl acetate fraction of 0.024±0.0011, ethanol fraction of 0.021±0.00024 and water fraction of 0.024±0.00019. Hydrogen peroxide scavenging ability of 70% ethanol extract was －0.0029±0.00040 and the others were as follow; methylene chloride fraction (－0.0042±0.00058), ethyl acetate fraction (－0.003± 0.0041), ethanol fraction (－0.0029±0.0015) and water fraction (－0.0028±0.00090).
