摘　　要：为了解不同山楂制品中金属元素的含量高低,采用干法灰化样品,以原子吸收光谱法测定20种不同山楂制品中的铁、锌、铜、铅、镁、钠、钙7种微量金属元素的含量。结果表明,样品中都含有丰富的人体必需元素,其中钙的含量最高,对人体有害的铅的含量均在国家标准范围之内,不会产生危害,并且不同品牌不同生产厂家生产的山楂产品中同一种金属元素的含量有一定差异。In order to learn about the amounts of metal elements in different hawthorn products,we used an AAS method with dry-ash samples to determine seven trace metal elements including Fe,Zn,Cu,Pb,Mg,Na,Ca in 20 kinds of hawthorn products. The present study shows that samples are rich in trace elements which human body needs. And calcium content has the highest level.The lead content is no harm within the scope of national standard all. The amounts of same metal elements in hawthorn products from different manufacturer is discrepant.
