不同品种巴旦杏仁中微量元素及总黄酮含量的比较研究

Determination of Trace Elements and Total Flavone in Different Variant of Amygdalus communis L.for Uighur Medicine

用火焰原子吸收光度法测定了6个品种巴旦杏仁中的K，Na，ca，Fe，cu，Zn，Mn，Mg等8种元素含量，并用紫外-可见分光光度法测定了总黄酮含量。结果表明，巴旦杏仁含有丰富的人体必需的微量元素，其中纸皮巴旦杏仁中K，Ca，Mn，Zn的含量普遍高于其它品种。微量元素测定方法的回收率在96．9％～101．7％之间，RSD值在0．74％～1．85％之间。总黄酮含量在不同品种之间呈现出较大差异，其中晚丰巴旦杏仁中总黄酮量高达1．75％，明显高于其它品种。为新疆巴旦杏资源的进一步研究和综合开发利用提供了新的科学依据。

The total flavonoids content in different variant ofAmygdalus communis L. for Uighur medicine were determined by UV spectrophtometry and eight trace elements were determined by FAAS respectively. The flavones average content in samples was 12.77 mg/g calculated by rutin. The result shows that it contains many essencial elements such as K, Na, Ca and Mg. The recovery in standard addition was in the range of 96.9% - 101.7% with RSD less than 1.85%. It proved by the experimental results that the later showed a higher value of nutrition and that a strong scientific warranty was obtained for the broader exploitation of the Amygdalus communis L.
