Carrot represents one of ten most important vegetable species. Carrot root is very nutritious and rich in
minerals. It positively affects on vision because it is rich with vitamin A and beta caroten. Magnesium is a
mineral which belongs to a group of macroelements and is important for the plant as it is the component
part of the chlorophyll molecule. Lack of magnesium causes interveinal leaf chlorosis and yellow sprinkles.
In human organism it has important role as calcium and phosporus regulator in bones and for proper heart

to compare the results from the analyzed samples regards to the place of purchase. Sampling of orange
carrot root in city of Zagreb was performed in 5 market chain branches, 5 market places and in 5 stores
with ecological products. Magnesium was determined by atomic apsortpion spectrofotometry (AAS) after
digestion with HNO3 and HClO4 in microwave oven. Magnesium content of orange colored carrot roots
ranged from 0.07 to 0.21% Mg DM or from 5.73 to 24.33 mg Mg 100 g-1 fresh matter. Average the highest
Mg content was determined in carrots from chain stores.
