摘　　要：采用电感耦合等离子体-原子发射光谱法(ICP-AES)和电感耦合等离子体-质谱法(ICP-MS)联合测定胡芦巴叶、茎和种子中13种矿质元素的含量,并考察了13种元素在胡芦巴不同部位的分布情况。分析结果表明,胡芦巴中13种矿质元素在各部位中的加合量(μg·g^(-1))由高到低的顺序依次为:叶(527644.60)>茎(382441.80)>种子(108389.20),各元素在不同部位分布也不同,其中Ca、K、Mg、Mn、Zn、Se在叶中含量总体相对较高;而P、Cu、Cr在种子中含量较高,其他各元素在3个部位的含量差异不大。此外,种子中Zn/Cu仅为5.30,有利于调节人体中胆固醇的异常代谢,与胡芦巴降血脂活性部位在种子中的结果一致。The contents of 13 mineral elements in leaves,stems and seeds of fenugreek were determined by inductively coupled plasma atomic emission spectrometry（ICP-AES） combined with inductively coupled plasma mass spectrometry（ICP-MS）,and the distributions of the 13 elements in the different parts of fenugreek were also analyzed.Experimental results showed that the order from high to low for the additive weight（μg ？ g^（-1）） of the 13 elements in each part was as follows：leaves （527644.60）stems（382441.80）seeds（108389.20）,and the contents of elements varied in different parts of fenugreek,the contents of Ca,K,Mg,Mn,Zn and Se are overall highest in leaves; the elements P,Cu and Cr are richest in seeds,and the other elements are not significantly different in each part.Moreover,the Zn/Cu value is only 5.30 in seeds which showed that the seeds have remarkable pharmacological activity of regulating the cholesterol metabolism disorders and was in consistent with the result that the active part of fenugreek for the anti-hyperlipidemia is seeds.
