| 目的 建立电感耦合等离子体原子发射光谱(ICP-AES)测定西洋参药材中无机元素含量的方法。方法 采用HNO3微波消解西洋参样品,电感耦合等离子体发射光谱法(ICP-AES)测定西洋参药材中无机元素含量。结果 西洋参样品中,除检测到常规元素外,所含重金属元素铜、镉、铅的限度均符合中国药典标准。用该方法测定元素的相对标准偏差低于5%,回收率在95%~105%之间,结果可信度高。结论 该方法结果可靠,操作方便,可用于西洋参等中药材的无机元素含量测定。 |

| Objective To establish an ICP-AES method for the determination of inorganic elements in Radix Ginseng.Methods American ginseng samples were digested by microwave with HNO3, and the inorganic elements were assayed by ICP-AES.Results In American ginseng samples, in addition to conventional elements detected, the contained heavy metals copper, cadmium and lead limits were in line with the standards of Chinese Pharmacopoeia.For all of the elements analyzed, the relative standard deviations(RSD) were less than 5% and the recoveries of most elements were in the range from 95.0% to 105.0%.Conclusion The method is reliable and easy to operate so it can be used for determination of inorganic elements in American ginseng and other Chinese herbal medicines. |
