A coordination polymer of Cd with benzene-1,3-dicarboxyl-ate and 1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane.

The title Cd(II) coordination polymer, catena-poly[[{1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane}cadmium(II)]-μ-benzene-1,3-dicarboxyl-ato], [Cd(C(8)H(4)O(4))(C(30)H(28)N(6))](n), was obtained by reaction of CdCO(3), benzene-1,3-dicarboxylic acid (H(2)btc) and 1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane (L). The Cd(II) cation is six-coordinated by an N(2)O(4)-donor set. L acts as a bidentate ligand and btc anions link Cd(II) centers into a chain propagating parallel to [010].

[Determination of the contents of trace elements in chinese herbal medicines for treating respiratory system diseases].

There is an intimate connection between trace elements and body healthiness, trace elements and organism depend on each other, and each trace element exists with certain proportion, which preserve physio-function. If the balance is of maladjustment, diseases may occur or develop. The trace elements were determined in 16 kinds of Chinese herbal medicines by atomic absorption spectrometry.

[Analysis and study of total flavone and trace element in carthmus tinctorius L].

The content of total flavone in carthmus tinctorius L in Xinjiang was determined by ultraviolet spectrophotometry with scan from 200 to 400 nm where the maximum absorption wavelength was 267.00 nm. The contents of ten trace elements and constant elements in carthmus tinctorius L including potassium, sodium, calcium, magnesium, iron, chromium, nickel, manganese, copper and zinc were determined by flame atomic absorption spectrophotometry.

[Study on the determination and blurred classification of metal elements content in danshen etc 11 kinds of Chinese traditional medicine].

The contents of potassium, calcium, magnesium, iron, manganese, copper, zinc and chromium in 11 kinds of Chinese traditional medicines such as Danshen, Gouqizi, Dangshen, Jiaogulan, Dongchongxiacao, Huangqi, Rougui, Xixin, Longdancao, Shanzhuyu and Duzhong were determind by flame atomic absorption spectrophotometry, in order to study the interrelation between metal elements and the therapeutic effect through the method of blurred classification. The results showed that the cluster in 7 kinds of medicines was similar when the relative coefficent was 0.50; cluster in 3 kinds of medicines was similar when the relative coefficent was 0.

[Determination and analysis of trace element manganese and amino acids content in aloe tea].

The content of trace element manganese in aloe tea was determined by atomic absorption spectrophotometry. The contents of 17 kinds of amino acids in aloe tea were determined with amino acids instrumentation. The results showed that there are comparatively rich manganese and amino acids in aloe tea.

[Determination of the content of inorganic elements in taponin tablet recipe].

The content of seven inorganic elements in Taponin tablet recipe, including calcium, magnesium, iron, manganese, copper, zinc and cadmium were determined by flame atomic absorption spectrophotometry. The results showed that there were comparatively rich inorganic metal elements. Content of the seven metal elements is that iron > calcium > magnesium > zincr > copper > manganese > cadmium, the content of iron was higher significantly than other inorganic elements in Taponin tablet recipe.

[Determination of the contents of Ca, Mg, Fe, Cu and Zn in suxiao jiuxin pill and the analysis of Ca/Mg and Cu/Zn values].

The content of five metal elements in Suxiao Jiuxin pill, such as calcium, magnesium, iron, copper and zinc were determined by flame atomic absorption spectrophotometry. The ratio of Ca/Mg and Cu/Zn in Suxiao Jiuxin pill had been studied. The results showed that calcium, magnesium, iron, copper and zinc elements in Suxiao Jiuxin pill have comparatively rich.
