Abstract: Cyclocarya paliurus (Batal) Iljinskaja is a kind of traditional healthy food resource in China.In this paper the simultaneous determination of nutritional elements in its leaves and their extract was performed by inductively coupled plasma mass spectrometry (ICP-MS) with microwave-assisted process (MAP) for the sample preparation.The concentration of’ K.Ca.Mg in the leaves as dry matter is more than 2500 g/g.and that of Mn,Fe.Al ranged between 100 ~ 1000 g/g.The contents of the elements showed insulin related function.as that of Zn.Mn.Cr.Ni,Li.Se.V in the level of’ 67.8 g/g.2.63 P g/g. 1 .38 g/g.2.63 g/g,0.42 g/g.0.56 g/g.5.38 g/g.respectively. The solubility of these elements in water was dependent on the extraction temperature. Higher exfraction ratio could be obtained by artificial gastric acid or with microwave extraction method.
