ABSTRACT
In present study the bulb of Allium sativum, root of Rheum australe and fruit of Terminalia chebula were selected for trace elements analysis by Atomic Absorption Spectrophotometer. The plant samples were digested with concentrated Nitric acid (HNO3) and concentrated Perchloric acid (HClO4). The analysis for trace elements in the sampled plants indicated that Sodium, Potassium, Calcium, Magnesium, Copper, Zinc, Iron, Cobalt, Manganese, and Lead were present in all samples of all selected plant species at different levels which play a vital role in cure of diseases. The results of the present study provide justification for the usage of these plants in daily diet for nutrition as well as for medicinal usage in the treatment of different diseases. Toxic element Pb were also found but at low concentration. These results can give the importance about these plants and used to set new standards for prescribing the dosage of the herbal drugs prepared from these plant materials in herbal remedies and in pharmaceutical companies.
