| Research Abstract |
Majority of cadmium was distributed in precipitated fraction of homogenate of the higher plant Portulaca oleracea. Digestion of the precipitate with pectinase released cadmium in the solution. Cadmium-binding substance was purified from the solution using several steps of chromatography, where detection method for soft-metal chelator that was newly developed was applied. The structure of the purified substance was determined to be polysaccharides by NMR spectrometry.
