摘要
采用电感耦合等离子体原子发射光谱法测定当归补血汤中多种微量元素，考查当归、黄芪以不同的配比进行煎煮时微量元素的溶出情况。实验证明、当归、黄芪生药材及水煎液经硝酸-高氯酸体系消化，样品消解完全，可以满足ICP-AES检测的要求。相对标准偏差为0．82％～5．56％，加标回收率为97．2％～115．4％，完全能满足中草药中微量元素的测试要求。而各种微量元素的溶出率均以当归、黄芪为1：5的配比的共煎液中各种微量元素溶出率最高，证实了该配伍的合理性。文章为药剂学研究提出了一个简便、准确和可行的研究方法的同时，也对当归补血汤配伍合理性进行了考察，为其临床疗效提供了有效依据。
The method for the determination of trace elements in danggui blood-supplementing decoction by inductively coupled plasma atomic emission spectrometry（ICP-AES） was presented. The contents and solubility of the trace elements in Angelica sinensis and Radix Astragali of different proportion were compared. The recovery rates of the procedure were between 97. 2% and 115.6%. The RSDs were between 0. 82% and 5. 56%. When Angelica sinensis.. Radix Astragali was 1 ： 5, the solubility of trace elements was the highest. The couplng of danggui blood-supplementing decoction was proved reasonable. The method was simple, rapid, precise, convenient and suitable for traditional Chinese medicine.
