鱼蓼中微量元素的研究

Study on Content of Trace Elements in Polygonum lapathifolium L.

研究鱼蓼中的微量元素含量,为开发利用鱼蓼提供重要参考。采用火焰原子吸收光谱法分析了鱼蓼中的Fe,Zn,Cu,Mn,Co,Cd,Pb含量。结果表明:鱼蓼中的Fe,Zn,Cu,Mn,Co含量分别为543.08,183.01,15.91,145.22,5.97mg/kg,而重金属元素Cd,Pb未检出。分析认为,黔东南州榕江县原生态鱼蓼是一种富含营养元素的香料,可对其进行开发利用。

The study on the content of trace elements in Polygonrmlapathifolirm L.has provided important reference for the development and utilization of Polygonrmlapathifolirm L..The content of Fe,Zn,Cu,Mn,Co,Cd and Pb in Polygonrmlapathifolirm L.is determined by flame atomic absorption spectrometry.The results show that the content of Fe,Zn,Cu,Mn and Co in Polygonrm lapathifolirmL.is 543.08,183.01,15.91,145.22,5.97 mg/kg respectively.While the content of Cd and Pb is not detected.The analysis suggests that the original ecological Polygonrmlapathifoli-rm L.in Rongjiang County of Qiandongnan Prefecture is a spice of nutrient-rich trace element,and can be exploited.
