STUDY ON ELEMENT CONTENT OF MEDICINAL PLANTS Clerodendrum colebrookianum AND Vitex negundo

Abstract

Medicinal plants are important part of health care system. Elements present in medicinal plants have a great role in the management and treatment of various diseases. The concentrations of elements in plant species depend on various factors like geographical location, genetic background, cultivation methods, environmental condition, etc. This present investigation was conducted to analysis the concentration of trace and macro elements in two selected traditionally used medicinal plants collected from local village areas of Nalbari District of Assam. Flame Photometry and Atomic Absorption Spectroscopy (AAS) techniques are used for quantitative analysis of various elements present in Clerodendrum colebrookianum and vitex negundo leaves. Eight trace elements (Fe, Cu, Ni, Mn, Zn, Na, K, Cr) were determined in these two medicinal plants. The present analysis may helpful for standardization of plant derived pharmaceutical drug.
