ICP-AES法检测芍药对矿质元素的吸收利用

摘要

The contents of K, Ca, Na, Mg, Fe, Cu and so on in the roots of Paeonia lactiflora Pall and in the soil in which they grew were determined by ICP-AES technique to study the mineral elements utilization of P. Lactiflora Pall. The results indicate that the elements utilization rate of P. Lactiflora Pall is different in different locations, so the contents of mineral elements in the roots of P. Lactiflora Pall and even the quality of medicinal materials coming from them in different locations are different The contents of Ca, Fe, Zn and so on in Chi Shao in Heilongjiang and Inner Mongolia are relatively high. The contents of mineral elements in soil influence not only themselves' utilization but also other mineral elements utilization of P. Lactiflora Pall.%为了分析芍药对土壤矿质元素的吸收利用规律,采用ICP-AES法检测了不同产地芍药根和相应土壤中K,Ca,Na,Mg,Fe,Cu等主要矿质元素含量.结果表明:不同产地的芍药对土壤中矿质元素的吸收利用效率不同,反映在不同产地的芍药根中有些矿质元素含量有明显差异,从而使各地芍药药材质量在矿质元素方面也有差异,以黑龙江和内蒙古等地的赤芍中Ca,Fe,Zn等元素含量偏高；土壤中有些矿质元素不仅影响芍药对这种元素的吸收利用,而且影响芍药对其他元素的吸收利用.
