Determination of nutritional elements in plant leaves using the Thermo Scientific iCAP 7400 ICP-OE

閱讀：1479 發(fā)布時(shí)間：2020-10-23

The commercial value of a plant as a food stuff or as a raw material for preparing medicines depends on the quality of the plant product. One measure of quality is the balance of different chemical and elemental constituents in the plant material. Typically the major elements (macronutrients, including calcium, potassium, phosphorus, nitrogen, magnesium, sulfur) as well as the trace elements (micronutrients, including boron, manganese, iron, nickel, copper, and zinc) are assessed to determine quality.

This allows the identification of nutrient deficiency, which can lead to a reduction in the quality of flowers, fruits or vegetables, produced by the plant. In addition, the elemental composition of the plant may explain the plant’s medicinal or toxic properties.

With the development of ionomics (which involves the quantitative and simultaneous measurement of plant elemental composition and changes in this composition in response to physiological effects and genetic modifications [1-3]) new techniques for the quantitation of plant ionoms or their parts became of high importance.

In this study the advantages of Thermo Scientific™ iCAP™ 7000 Plus Series ICP-OES for the determination of nutritional elements in plant matrices are discussed, using plant leaf analysis as an example.
