The content of macro- (P,K,Mg,Ca) and micro-elements (Fe,Cu,Zn,Mn) in samples of fermented tobacco was studied. These elements participate in the combustion process during the smoking. Several varieties of oriental tobaccos were grown in the experimental fiel of the Tobacco Institute, Prilep (FYR Macedonia) during the year of 2001 and 2002.The investigation included varieties of two most frequent grown tobaccos in Macedonia: Prilep and Yaka. The presence of the elements analysed in leaves of these varieties was within the limits characteristic for these tobaccos. Mn was the most and Cu the least adundant in leaves. Variations in contents of Mn were small in contrast to Cu, whose contents were the most variable in comparison with all other elements in leaves. The content of macroelements in blossoms was significantly lower than in leaves. This decrease ranged from 50% for P and K, up to 30 times for Ca. The content of Cu was four times lower than that in leaves, whilst contents of Mn and Zn were eight times lower than those in leaves.
