The study on the element transference characteristics and element speciation in the extract of Cyclocarya paliurus (Batal.) Iljinskaja leaves

Abstract

The study on the element transference characteristics and element speciation in the extract of Cyclocarya paliurus(Batal.) Iljinskaja leaves was performed by FIA-ICP-AES on the basis of C-18 bonded silica gel column separation and microwave digestion/extraction for sample treatment, Higher transfer ratio could he obtained by artificial gastric acid or with microwave extraction method, The contents of inorganic species and organic species of the four elements in the microwave extract at the temperature of 100 degrees C are as follows, Zn: (4. 46+/-0. 13) mu g/g and (8. 16+/-0. 15) mu g/g; Mn: (35. 7+/-1. 1) mu g/g and (91. 2+/- 3. 2 mu g/g); Mg: (156+/-9) mu g/g and (513+/-11) mu g/g; Fe: (3. 28+/-0. 19) mu g/g and (8. 43+/-1. 15) mu g/g, respectively.
