摘　　要：对唐古特白刺粗多糖中17种矿质元素(Cu、Zn、Fe、Mn、Co、Ni、Se、Cr、Mg、Ca、K、Na、P、As、Hg、Pb和Cd)进行了测定,结果表明:唐古特白刺粗多糖不仅含有较多的人体必需的常量元素(K、Ca和Na),而且还含有较多的人体必需微量元素(Fe、Zn和Mn),尤其以Fe的含量为高;非必需的微量元素(有害元素As、Hg、Pb、Cd)的含量则比较低,低于1 mg/kg。In this paper, 17 kinds of mineral elements （Cu, Zn, Fe, Mn, Co, Ni, Se, Cr, Mg, Ca, K, Na, P, As, Hg, Pb and Cd） in crude polysaccharides from Nitraria tangutorum Bobr. were detected, and it indicates that the crude polysaccharides not only contain high levels of essential constant elements for human body, such as K, Ca and Na, but also are very rich in essential Irate elements （Fe, Zn and Mn）, with the Fe more than any other kind of trace elements; On the other hand, the content of the non-essential trace elements that are generally harmful to human body （As, Hg, Pb and Cd）, is very low in the the sample of crude polysaccharides, that is, under 1 mg/kg.
