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.
