Content of Heavy Metals in Mulberry Fruits and Their Extracts-Correlation Analysis

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-
