采用高压消解罐对样品进行处理,将化学计量学应用于ICP-AES测定种植刺五加、野生刺五加、五加皮、白参和西洋参中Na、Mg、Se、Pb、K、Fe、Ca、Sr微量元素的含量。该方法操作简单、快速、灵敏度高,回收率在95.54%—100.8%之间,相对标准偏差小于0.0470%。实验结果表明,5种物质中均含有人体所需的大量微量元素,而且对比种植刺五加和野生刺五加发现,野生刺五加的营养价值优于种植刺五加。从微量元素含量的角度上,刺五加和人参不具有相似性。 The samples were treated with high-pressure digestion tank, and the stoichiometry was applied to the determination of Na, Mg, Se, Pb, K, Fe and Ca in Acanthopanax senticosus, Acanthopanax senticosus, Ca, Sr trace elements content. The method is simple, rapid and sensitive. The recoveries are between 95.54% -100.8% and the relative standard deviations are less than 0.0470%. The experimental results show that the five kinds of substances contain a large amount of trace elements required by the human body, and compared with the acanthopanax senticosus and the acanthopanax senticosus, it is found that the acanthopanax senticosus has better nutritional value than acanthopanax senticosus acanthopanax senticosus. From the perspective of trace element content, Acanthopanax and ginseng do not have similarities.
