【摘要】Water-soluble algal polysaccharides (APS) (alginic acid, fucoidan and laminaran) possess many pharmacological activities. The results of this study showed that the APS- Ce4+ complexes have some enzyme-like activities. Fucoidan and its complex with Cea+ have activities similar to those of SOD. The activities of laminaran, alginic acid and their complexes are not measurable. The APS do not show measurable activities in the digestion of plasmid DNA. In contrast, the APS- Ce4+complexes show these measurable activities under the comparable condition when APS bind Ce4 + and form homogenous solutions. The laminaran- Ce4 + complex shows the most obvious activity in the digestion of plasmid DNA, pNPP and chloropyrifos under neutral conditions. 【总页数】5页(29-33)
