Polyalthia longifolia (Sonn.)Thw. commonly called as, ‘Ashok’ is an evergreen tree native to India. The different extracts of leaves and seeds of the plant have been used in traditional system of medicine. Therefore, the metal analysis of leaves and seeds of the plant has been carried out. The powder of leaves and seeds of Polyalthia longifolia (Sonn.)Thw. were analyzed for metal contents. Analysis was carried out by using different standard methods such as kjheldal’s, Colorimetric, Flame photometry and Atomic adsorption spectrophotometer. It was found that Nitrogen, Phosphorous, Potash was found in negligible amount but Zinc, Copper, Iron and Manganese were found in large amount. It was observed that Zinc, Copper, Iron and Manganese were present in large amount in leaves than the seeds. The present study indicates that leaves and seeds of Polyalthia longifolia (Sonn.)Thw were potential source of Zinc, Copper, Iron and Manganese.
