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。 After the roots, stems and leaves of Medicinal Plant Calendula officinalis were treated by nitrification, 28 kinds of inorganic elements were determined for the first time by fluorescence, AAS and ICP methods, among which the essential macro elements Ca, K, Mg, P, and Ni were essential. ; The necessary trace elements Fe, Sr, Mn, Zn, Cu, Ni, Cr, V, Mo, Co, Se (4+), the content of the first four species is relatively high; harmful trace elements Pb, Cd, Hg, Be content is lower The amount of poisoning. The contents of the measured elements are different, and they vary from site to site. Leaves are sensitive parts of the inorganic elements in the plant.
