ELEMENTAL ANALYSIS OF Aerva lanata (L.) BY EDX METHOD

Abstract

Trace elements concentrations in Aerva lanata was studied using SEM-EDX technique. The aim of this study is to determine qualitatively and quantitatively trace elements in Aerva lanata and their medicinal roles in the human body. The whole plant was analysed for their trace element contents. The plant samples were found to contain essential trace elements such as Calcium, Magnesium, Silicon, Chloride, Potassium and Carbon which are well known for their important roles in herbal drugs. Most of the medicinal plants were found to be rich in one or more of the essential elements under study. The elemental concentrations of different element in Aerva lanata and their biological effects are discussed.
