黄花蒿叶矿质元素含量的研究

Studies on Mineral Elements Content in Leaves of Artemisia Annua L

[目的]了解广西野生黄花蒿的矿质元素含量,为建立黄花蒿质量标准提供参考。[方法]在广西都安县、田林县、龙胜县、岑溪市和北海市各选1个种群采集黄花蒿叶片,测定黄花蒿叶中的大量元素、微量元素及重金属的含量。[结果]黄花蒿叶中含有丰富的P、K、Ca、Mg等大量元素和Fe、Mn、Zn等微量元素,而对人体有害的重金属元素的含量少。N、K、Ca、P、Mg的平均含量分别为32.6、31.1、8.94、4.143、.02 g/kg,Fe、Mn、Sr、Zn、Ni、Se的平均含量分别为4061、22.5、57.7、52.83、.600、.069 mg/kg。黄花蒿叶中重金属元素的含量由大到小依次为:Cu>Cr>Pb>As>Co>Cd>Hg。[结论]广西产中药材黄花蒿叶具有较高的矿质营养价值。

[ Objective ] The study was to understand the mineral elements content in wild Artemisia annua L and provide referenee for the establishment of its quality standard. [Method] The leaves of A. annua L of a population in Duan, Tiaulin, Longsheng county, Cenxi and Boihai city of Guangxi were collected respectively, and the contents of macroelement, microelement and heavy metals in leaves were determined. [ Result] Macroelement such as P, K, Ca and Mg and microelement such as Fe, Mn and Zn were abundant in the leaves of A. annua L and the contents of heavy mental elements which were harmful to human were few. The average content of N, K, Ca, P, Mg was 32.6, 31.1, 8.94, 4.14, 3.02 g/kg resp., and the average content of Fe, Mn, St, Zn, Ni and SC was 406, 122.5, 57.7, 52.8, 3.60 and 0.069 mg/kg resp. The content of heavy metals was in order as Cu 〉 Cr 〉 Pb 〉 As 〉 Co 〉 Cd〉 Fig. [ Conelusion] Leaves of A. annua L produeed in Guangxi had higher value in mineral nutrition.
