摘　　要：以广西产山楂叶为原料,将样品微波消解后,采用ICP-AES/ICP-MS同时测定其中Mg,P,Ca,Sr等无机元素,结果显示该法具有良好的精密度及准确度,完全可以满足样品中无机元素的测定要求。在所测定的24种无机元素中,其含量顺序依次为:Ca>K>P>Mg>Ba>Sr>Al>Fe>Na>Mn>B>Pb>Zn>Cu>Ti>Ni>Be>Co>V>Cr>Li>Tl>Cd>Mo。The contents of inorganic elements such as Mg,P,Ca,Sr in Crataegus pinnatifida Bge.growing in Guangxi were determined by ICP-AES and ICP-MS technique with microwave digestion.The analytical results indicated this method was applied to the determination of inorganic elements in the sample with good accuracy and precision.The order of the 24 elements contents were Ca〉K〉P〉Mg〉Ba〉Sr〉Al〉Fe〉Na〉Mn〉B〉Pb〉Zn〉Cu〉Ti〉Ni〉Be〉Co〉V〉Cr〉Li〉Tl〉Cd〉Mo.
