侧金盏花各部位中无机元素的测定

DETERMINATION OF INORGANIC ELEMENTS IN DIFFERENT PARTS OF ADONIS AMURENSIS REGEL ET RADD

药用植物侧金盏花的根,茎、叶经硝化处理后,用荧光、AAS和ICP法首次测定了28种无机元素,其中人体必需宏量元素Ca、K、Mg、P、Ni含量高;必需微量元素Fe、Sr、Mn、Zn,Cu、Ni、Cr、V、Mo、Co、Se(4+),前4种含量较高;有害微量元素Pb、Cd、Hg、Be含量低于致毒量。所测元素含量各异,且因部位不同而异,叶是该植株中无机元素富集之敏感部位。

Twenty-eight inorganic elements in different parts of Adonis amurensis Regel et Radd were determined for the first time by means of fluorescence, AAS and ICP after these parts, including the root, stem and leaves were digested. The contents of the elements essential to. human body, such as Ca, K, Mg, P and Na were comparativly higher. Among the essential trace elements , contents of Fe, Sr, Mn and Zn were comparatively higher.The harmful trace elements, such as Pb, Cd, Hg and Be were less than their toxic doses. Leaf was the sensitive part rich in these elements.
