Abstract

Present investigation was carried out to estimate mineral elements in Rheum emodi Wallr. by atomic absorption spectroscopy. The samples of R. emodi Wallr., both wild and cultivate populations, were collected from different localities at different altitudes of Uttarakhand, India. The concentration of micro- and macroelements was different in roots and leaves. The concentration of mineral elements was found in both the leaves and roots in the order of K > Ca > Fe > Mn > Na > Zn > Co > Li > Cu.

摘要

本研究采用原子吸收光谱法测定了藏药尼泊尔蓼（Rheum emodi Wallr.）中的矿质元素。采集了来自印度北阿坎德邦不同海拔高度不同地点的野生和栽培尼泊尔蓼样本。根和叶中的微量元素和宏量元素浓度不同。在叶和根中，矿质元素的浓度顺序为 K > Ca > Fe > Mn > Na > Zn > Co > Li > Cu。
