ABSTRACT: The aim of this research was the determination of
heavy metals’ (iron, copper, zinc, manganese, cadmium, nickel and lead) contents
of white, red and black mulberry fruit grown in southeast region of Serbia, and
their extracts. The content of all metals was confirmed in the fruits. All of
tree types of mulberry contained the highest content of iron in the fruit and
the lowest content of Cd. The level of iron in all assayed fruits species was
ranged between 23.06-57.38 mg?100g?1. The concentration range of cadmium for
the tested fruits was found to be from 1.77 to 2.46 μg?100g?1 in
fruit of Morus nigra L. and Morus alba L., respectively. The content
of metals in the fruit of white mulberry decreases in the following order: Fe > Mn > Zn > Cu > Ni > Pb > Cd. The
content of metals in the fruit of red mulberry by decreasing the value is: Fe > Zn > Mn > Cu > Ni > Pb > Cd and
in the fruit of black mulberry decreases in the following order: Fe > Zn > Cu > Mn > Ni > Pb > Cd. In
addition, an analysis of mulberries extracts showed a significant transfer of
heavy metals during extraction procedure; therefore, the corresponding
extraction coefficients reached values up to 73.09%. Those were especially high
in the acetone-
