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 contents of K, Na, Ca, Fe, Cu, Zn, Mn, Mg and other elements in 6 almond varieties were determined by flame atomic absorption spectrophotometry. The content of total flavonoids was determined by UV-Vis spectrophotometry. The results showed that almonds were rich in essential trace elements. The content of K, Ca, Mn, and Zn in almonds was generally higher than other varieties. The recovery of trace elements was between 96.9% and 101.7%, and the RSD was between 0.74% and 1.85%. The content of total flavonoids showed a great difference among different varieties, among which the total flavonoid content in the late Fengba almond was as high as 1.75%, which was significantly higher than other varieties. It provides a new scientific basis for the further research and comprehensive development and utilization of the almond resources in Xinjiang.
