| 摘 要： | 采用火焰原子吸收光谱法对嫩、老(成熟)荷叶中K、Ca、Mg、Mn、Fe、Zn、Cu7种营养元素的含量进行测定。结果表明,嫩、老荷叶中7种营养元素含量高低顺序一致,依次为KCaMgMnFeZnCu,但成熟荷叶中钙、锰含量明显高于嫩荷叶,约为嫩荷叶的两倍,铁含量稍高于嫩荷叶,钾、镁、锌、铜含量略低于嫩荷叶。其中成熟荷叶中锰的含量为738.04μg.g-1,比一般中药高出近20倍,荷叶的多种药用价值可能与富含微量元素锰有密切关系。

| Abstract: | The contents of K,Ca,Mg,Mn,Fe,Zn,Cu were determined in tender and mature lotus leaves by flame atomic absorption spectrometry.The contents of above-mentioned seven nutrimental elements decreased in sequence followed by K>Ca>Mg>Mn>Fe>Zn>Cu,both in tender and mature lotus leaves.The contents of Ca and Mn in mature lotus leaves are nearly twice as much as those in the tender leaves.The iron in the mature lotus leaves is a little higher than that in the tender leaves,while the contents of K,Mg,Zn,Cu are slightl... |
