In this study,samples are collected from Weihai of Shangdong Province,China,and from New Zealand where are the main production areas of <i>Undaria Pinnatifida</i>.And the contents of polysaccharides and heavy metals were measured.The difference of the conventional physical and chemical components from different localities was analyzed and compared as well.In addition,the extracted polysaccharide was detected by attenuated total reflection(ATR) infrared spectrum,and the characteristic group of sulfate group was measured.The polysaccharide was determined to be a sulfated lipopolysaccharide,and the content of the sulfate radical group was related to the effect of fucoidan.Therefore,the content of the sulfate radical group in the sample was further measured in order to further explore the structure-effect relationship of fucoidan in <i>Undaria Pinnatifida</i> which will good for choosing the suitable sample area for reference.
