Heavy Metal Analysis Of Some Phytotherapeutic Plants In Sanamavu Forest, Krishnagiri District Of Tamil Nadu, India.

Abstract

ABSTRACT Phytotherapeutic plants such as Aristolochia indica L. Bidens pilosa L. Clematis zeylanica L. (Pori.) Syn: Naravelia zeylanica L. Corallocarpus epigaeus (Rottl.) Ex Willd. and Plectranthus caninus L. are used as important source of medicine for village people near the Sanamavu Forest area, Krishnagiri District. The concentration of five heavy metals Cadmium (Cd), Lead (Pb), Arsenic (As), Mercury (Hg) and Thalium (TI) are investigated using Inductively Coupled Plasma Mass Spectrometer (ICP-MS). Heavy metal analysis shows that the high amount of lead (Pb) 2.36 mg/kg is identified in Plactranthus caninus L. and 1.80 mg/kg is in Clematis zeylanica L. (Pori.) The high amount of Cadmium (Cd) 0.143 mg /kg is identified in Plactranthus caninus L. and 0.097 mg/ kg in Corallocarpus epigaeus (Rottl.) Ex Willd. and the high amount of Arsenic (Ar) 0.11 mg/kg found in Plactranthus caninus L. and 0.039 mg/kg in Biden pilosa L. The high amount of Copper (Cu) 19.01mg/kg found in Clematiszeylanica L. (Pori.) Mercury (Hg) and Thalium(TI) are not detected in the five selected medicinal plants. This research goal is to identify and report heavy metals in the selected medicinal plants.
