Abstract

The concentrations of total polyohenolic compound from extract of Paulownia tomentosa Stued. were water-soluble extract 7.98%, methanol extract 12.30% and ethanol extract 11.63%. The free radical scavenger activities of three extracts at the levels of 0.5% were higher than that of BHT(butylated hydroxytoluene). In antioxidative activities measured the concentrations of TBARS(thiobabituric acid reactive substances) in tissues microsome induced with Fe$\^$++/ascorbate, the water-soluble extract was errdctively suppressed in liver and spleen. In antioxidative activities determined by thiocyanate method against lipid peroxidation using linoleic acid, the methanol extract showed the higher compared with other extracts, but BHT showed the highest antioxidative activity. These results suggest that fruit extracts of Paulownia tomentosa Stued. showed to have relatively high concentrations of polyphenolic compounds and antioxidative activities.
