Mineral Composition of Vegetable Biomass of Amaranthus L. Species

Abstract

The mineral composition is explored of the four species of The leaves were analyzed when the plants were in the vegetative phase of development. The element concentrations determined by techniques of atomic absorption spectrometry with inductively coupled plasma spectrometry. The order of the elements is as follows: mg/kg. Maximum content of Mg was 6,734.33, P 1,706.33, Fe 1,133.28 mg/kg. The content of heavy metals was in a safe quantity, except nickel. The highest coefficients of variation (%) are characteristic of the content of barium (45.07), sodium (31.18), vanadium (28.22) and potassium (26.62). The most stable is the content of phosphorus (3.25%). The mineral composition of leaves of amaranth showed its high value as a vegetable product.
