| 摘 要： | 采用电感耦合等离子体质谱(ICP-MS)法测定了湖北神农架产金银花花蕾中27种金属元素的含量。其中13种金属元素V、Cr、Mn、Fe、Cu、Zn、As、Se、Mo、Ag、Cd、Tl、Pb等采用普通模式检测,14种金属元素Li、Be、B、Mg、Al、Co、Ni、Ga、Rb、Sr、Te、Ba、Bi、U等采用碰撞/反应池技术(CCT)模式测定,以消除样品溶液中潜在的干扰。实验条件下,Co、Ni、Cr、Zn、Se、Mo、Ag、Pb等8种金属元素未检出。方法检出限Fe为9.789ng/mL、Cr为2.691ng/mL,Zn为1.803ng/mL,B为2.076ng/mL,Mg为1.977ng/mL,Al为3.024ng/mL,Ni为1.824ng/mL,其它元素为0.003～0.921ng/mL,精密度的RSD为0.146%～7.627%,加标回收介于90.0%～110.0%之间。

| Abstract: | The twenty seven metal elements in flowers of Lonicera japonica from Shennongnjia were determined by ICP-MS. There were fourteen such as Li, Be, B, Mg, A1, Co, Ni, Ga, Rb, Sr, Te, Ba, Bi and U were determined wish the collision/reaction cell technology for the elimination of potential interference. Detection limits for most elements were between 0. 003 and 0. 921ng/mL, and the precision （RSD） was among 0.15 % to 7.63; with good recovery （90;110%） . |
