Abstract:Samples were treated by wet microwave digestion procedure with HNO3/H2O2 and the mineral elements in bee-pollen of Brassica campestris L. were completely analyzed by inductively coupled plasma optical emission spectrometer (ICP-OES). The results showed there were 17 mineral elements in the samples. The RSD of the determined values were between 0.85% and 6.97%. And RSD of the contntes of14 elements was within 5%. Standard recovery rate of 13 elements was 93.5 %-107.3 % and 9 mineral elements was within 100 %±5 %. The mass fractions of such necessary macroelements, including S, P, K, Ca, Mg and Na, were 0.74%, 0.59%, 0.35%, 0.23%, 0.13% and 0.0064%, respectively. The contents of the microelement Fe, B, Zn, Mn, Se, Cu, Sr, Ba, Ti, Si and Al were 14.3, 6.41, 2.40, 1.64, 1.23, 0.69, 0.54, 0.44, 0.10, 50.7 and 25.8 mg/100g, respectively.
