摘　　要：采用电感耦舍等离子体质谱法（ICP—MS）同时测定槟榔、益智、砂仁、巴戟天等4种南药药材及水煎液中13种微量元素Cu、Zn、Mn、Fe、Co、Ni、Cr、Se、Sn、CA、As、Hg、Pb的含量，并计算出药材水煎液中各微量元素的溶出率。结果表明，4种南药中13种元素的溶出率存在一定差异，其中Mn、Se、Zn、Ni元素的溶出率较高，在12．3％～58．7％之间，Cr元素溶出率较低，为0％～0．2％之间。该结果为南药的有效成分研究提供了基础数据。The contents of thirteen trace dements Cu, Zn, Mn, Fe, Co, Ni, Cr, Se, Sn,Cd, As, Hg, Pb in Four Southern Herbs in China and their decoctions, were determinated by ICP - MS. And the dissolved rates of thirteen trace dements are calculated. The results show that the dissolved rates of thirteen trace dements are different in the above herbs. Among the thirteen trace dements, the dissolved rates of Mn , Se , Zn and Ni is higher within 12.3% --58.7%, while that of Cr is lower to 0% --0.2%. The results obtained will offer some basic data for the study of active components in the southern herbs in China.
