Functional properties of yam mucilage were investigated by physicochemical analysis. Yam mucilage was extracted from the root of yam and then separated into two fractions by its selective aggregation with isopropanol concentration. Each mucilge fraction showed the excellent binding properties with heavy metal ions Co, Cr and Cu. Cr showed the higher affinity with mucilage than Co and Cu at pH 6.3. In ACE inhibition, IC50 values of mucilage fraction 1 and 2 showed 8.99$\mu\textrm{g}$/${mu}ell$ and 7.1$\mu\textrm{g}$/${mu}ell$, respectively.
