Concentrations of selected macro and microelements in bee pollen with specific floral origin, harvested from Transylvania (Romania), were determined by flame atomic spectrometry (F-AES/AAS), considering the little information available on all over the world, particularly in this country. Potassium occurred at the highest concentrations in all samples (2483.51-7619.57mg kg-1), followed by calcium (552.89-2797.85mg kg-1) and magnesium (3554.96-205.14mg kg-1). The microelements presented average values of 18.83-134.70mg kg-1 (iron) and 18.77-60.51mg kg-1 (zinc). The mineral levels in unifloral bee pollens analysed were found to vary due to differences in the floral origin. Unifloral bee pollen samples were classified in three main clusters, based on their Ca, Mg, Fe and Zn content. The clusters analysis of the data reveals the classification of unifloral bee pollen in three main clusters, based on the quantification of their Ca, Mg, Fe and Zn content. These results confirm that Romanian bee pollen can be used by man as a natural source of nutritionally essential minerals and contribute for a better balanced diet or for special therapeutic applications.
