Abstract

By wet microwave digestion procedure with HNO3/H2O2to prepare samples,the mineral elements in Lycium chinense Mill were completely analyzed by inductively coupled plasma optical emission spectrometer(ICP-OES).The results showed there were 19 mineral elements in it.They are K,Na,S,P,Mg,Ca,Si,Al,Fe,Zn,B,Cu,Mn,Se,Pb,Sr,Ti,Ba and Cr.The RSD of results were between 2.41% and 10.1%.Among them,that of 10 elements was within 5%.The mass fraction of such necessary macroelements in the human body as K,Na,S,P,Mg and Ca were 0.96%,0.25%,0.22%,0.19%,0.080% and 0.077%,respectively.The contents of such microelements as Fe,Zn,B,Cu,Mn,Se,Sr and Cr were 5.97、1.34、1.09、0.88、0.57、0.52、0.33、0.055 mg/100g respectively.And the content of some other elements,Al is 9.35 mg/100g and Pb is 0.45 mg/100g.
