目的:比较4种含重金属矿物中成药中酸可溶性重金属和总重金属的含量。方法:采用人工胃液对制剂进行样品前处理,并采用电感耦合等离子体原子发射光谱法(ICP-AES)分别测定含重金属矿物中成药中酸可溶性重金属和总重金属的含量。结果与结论:酸可溶性重金属含量限度可作为含重金属矿物中成药的质控指标之一。
Objective: To compare the content of acid-soluble heavy metals and total heavy metals in four kinds of proprietary Chinese medicines containing heavy metal minerals. Methods: Samples were pretreated with artificial gastric juice and inductively coupled plasma atomic emission spectrometry (ICP-AES) was used to determine the content of acid-soluble heavy metals and total heavy metals in Chinese patent medicine containing heavy metal minerals. RESULTS AND CONCLUSION: The limit of acid-soluble heavy metal content can be used as one of quality control indicators for Chinese patent medicine containing heavy metal minerals.
