dc.description.abstract将微波辅助溶样/萃取(MAP)和电感耦合等离子体质谱(ICP-MS)联用,建立了对青钱柳叶干制品及其浸提物中多种矿质营养素进行同时测定的方法。背景干扰采用减去空白信号和选择合适的同位素等方法进行消除。经标准参考物验证,本方法具有较好的准确性和重现性。分析结果表明:青钱柳叶中的矿质营养素丰富,以干基计,含量高于2500g/g的元素有钾、钙、镁、锰、铁、铝的含量在100~1000g/g之间;锌.铜、钠的含量为10~100 g/g其中锌和锰的含量较高,分别为67.81g/和654.00g/g具有胰岛素样作用的微量元素铬、镍、 锂、硒和钒的含量分别为: 1.38 /g、 2.63 g/g、 0.42 g/g、 0.56 g/g、 5.38 g/g。上述所测元素在水中的溶出量均与温度有关。在以人工胃酸为溶媒时,这些元素有较大的溶出率。以水为溶媒、结合微波萃取也可获得良好的浸提效果。
dc.description.abstractCyclocarya 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.
