The composition analysis and electron donating activity of 4 kinds of Korean wild sannamuls[Cacalia firma Komar. (CFK), Aster scaber Thunb. (AST), Ligularia fischeri (Ledeb.) Turcz. (LFT), Synurus palmatopinnatifidus (Makino) Kitam., SDN)] were investigated. The Korean edible mountainous vegetable was named a sannamul or chwinamul in Korea, generally. Most of them, the characterization of the each vegetable was reported, individually without comparative research. This study was compared the proximate compositions, mineral, dietary fiber and electron donating abilities on 2,2-diphenyl-1-picrylhydrazyl (DPPH) of sannamuls. In the chemical analysis of sannamuls, CFK was shown higher value in ash ($5.4{pm}0.18%$), crude fat ($2.5 {pm}0.14%$), carbohydrate ($8.1{pm}0.21%$), potassium ($475.45{pm}0.34mg$) and magnesium ($64.70{pm}0.48mg$) than others. Each mineral of the 3 other samples was a similar value but phosphorus in LFT was contained $62.91{pm}0.43%$. The compositions of total dietary fiber of the samples were listed CFK LFT SDN AST and the $RC_{50}$ Value on DPPH radicals, LFK CFT AST SDN. These results have susggest that CFK and LFT may be useful for a funtional material to food development.
