Antioxidative activity and ${alpha}$-amylase inhibitory activity were investigated in the methanol extracts of 289 species of angiosperm plants native to Jeju Island in order to select the plant species containing bioactive materials for functional foods or medicines. The antioxidative activity, estimated by the DPPH radical scavenging capacity, was high in the galla of Rhus chinensis, the fruit of Platycarya strobilacea, and the stem of Cedrela sinensis. Particularly, the antioxidative activity of Rhus chinensis galla (94.2${pm}$0.8%) was very high even though compared to those of BHA (61.7${pm}$0.6%) and ascorbic acid (53.6${pm}$0.7%). The ${alpha}$-amylase inhibitory activity was 80% or above in 9 species including Cornus macrophylla (stem, leaf), Distylium racemosum (leaf) and Vaccinium oldhami (leaf). These results suggest that these plants could be potentially utilizable to develop bioactive materials for functional foods or medicines.
