Comparative determination of trace elements from Allium sativum, Rheum australe and Terminalia chebula by atomic absorption spectroscopy

摘要

In present stu dy the bu lb 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 Sodiu m, Potassiu m, Calcium, Magnesium, Copper, Zinc, Iron, Cobalt, Manganese, and Lead were present in all samples of all selected p lant species at different levels which play a vital role in cure of diseases. The resu lts of the present study provide justification for the u sage of these plants in daily diet for nutrition as well as for medicinal u sage 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 stand ards for prescribing the dosage of the herbal drugs prepared from these plant materials in herbal remedies and in pharmaceutical companies
