Comparison of trace elements in traditional Chinese medicine and traditional Chinese medicine by ICP-MS method

本文采用电感耦合等离子体质谱(ICP-MS)结合微波消解的方法,比较煅龙骨、煅牡蛎、生石膏、滑石、芒硝、代赭石、琥珀、瓦楞子等8种矿物类中药传统饮片和其配方颗粒中微量元素铅、铜、锰、镍、铬、锌、砷、锑、镉的含量。结果表明矿物类中药和其配方颗粒的微量元素含量存在一定差异。

in this paper, the inductively coupled plasma mass spectrometry （ICP-MS） combined with microwave digestion method, compared the calcined keel, calcined oyster, gypsum, talc, Glauber＇s salt, red ochre, amber, coneha Arcae etc. 8 kinds mineral traditional Chinese medicine Yinpian and dispensing granule of trace elements lead, copper, manganese, nickel, chromium, zinc, arsenic, antimony, cadmium content.
