采用微波消解法处理小茴香样品,电感耦合等离子体发射光谱( ICP-AES)测定其中Na、K、Sr、Ca、Mg、P、As、Zn、Pb、Co、Cd、Ni、Ba、Fe、Mn、Cr、Cu、Al、Ti 和 B 20种常量和微量元素的含量。20种元素的检出限为0．00002~0．00468μg·mL-1,回收率为89．50%~107．89%,相对标准偏差( RSD)均小6%。结果显示,小茴香果实及其嫩叶中除含有人体必需的常量元素K,Na,Ca,Mg,P外,还含有Fe、Zn、Mn、Cr、Co等必需的微量元素和其他元素Ti、B、Ni、Al、Sr、Ba等。%The contents of 20 elements of Na,K,Sr,Ca,Mg,P,As,Zn,Pb,Co,Cd,Ni,Ba,Fe,Mn,Cr,Cu,Al,Ti and B in Foenicu-lum vulgare Mill were determined by ICP-AES,and the samples were pretreated by microwave digestion method. The detection limits were 0. 00002~0. 00468 μg·mL-1 ,and the recovery rates were 89. 50% ~107. 89%,the precisions were less than 6%. Five mac-roelements,K,Na,Ca,Mg and P,five essential microelements,Fe,Zn,Mn,Cr and Co,and seven other elements,Ti,B,Ni,Al,Sr and Ba were detected in all samples.
