title: Quantification of mineral elements of Rheum emodi Wallr. (Polygonaceae).
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.
