The ten trace elements of copper, iron, zinc, manganese, cobalt, nickel, calcium, magnesium, cadmium and lead in the solution are determined by atomic absorption spectrometry. The results obtained show that antipyretic and antidote contains higher amount of Ca, Mg, Fe, Zn and Mn than other elements.

摘要

将11种药物，包括（维生素C）强力银翘、黄连上清、三黄、感冒清、复方穿心莲、鼻炎康、板蓝根冲剂、牛黄解毒、中甘片、双黄连口服液和清热解毒口服液，用硝酸-高氯酸混合酸进行消解。采用原子吸收光谱法测定溶液中铜、铁、锌、锰、钴、镍、钙、镁、镉和铅这10种微量元素。结果表明，解热解毒类药物中钙、镁、铁、锌和锰的含量高于其他元素。
