Analysis of Trace Elements in Some Medicinal Plants by NAA and AAS Techniques 1
—The content of elements in 12 Indian medicinal plants was analyzed by instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) techniques. Specific parts of different medicinal plants like bulb, tuber, flower, gum, and rhizomes, which are often used in Indian Ayurvedic system, were used for the study. The element concentrations in different part of medicinal plants and their biological effects on humans are discussed.
INAA and AAS study of essential trace elements in ayurvedic Indian medicinal plants
Specific parts (leaves and fruits) of different medicinal plants often used in Indian ayurvedic system were analysed for 18 elements (K, Mn, Na, Fe, Zn, Cu, Co, Br, Sm, Cl, La, Al, Cr, Ca Cd, Ni, Pb and Hg) by employing instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) techniques. The samples were irradiated with thermal neutrons in a nuclear reactor and the induced activities were counted by γ-ray spectrometry using efficiency calibrated high resolution high purity germanium (HPGe) detector. Most of the medicinal plants were found to be rich in one or more of the elements under study. The elemental concentration in different part of medicinal plants and their biological effects on human beings are discussed.

Elemental analysis of some medicinal plants used in the Indian Ayurvedic system was performed by employing instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) techniques. The samples were irradiated with thermal neutrons in a nuclear reactor and the induced activity was counted by gamma ray spec-trometry using an efficiency calibrated high resolution high purity germanium (HPGe) detector. Most of the medicinal plants were found to be rich in one or more of the elements under study. The variation in elemental concentration in same medicinal plants samples collected in summer, winter and rainy seasons was studied and the biological effects of these elements on human beings are discussed.

Specific parts (fruits and seeds) of different medicinal plants often used in Indian Ayurvedic system were analysed for 18 elements (K, Mn, Na, Fe, Zn, Cu, Co, Br, Sm, Cl, La, Al, Cr, Ca Cd, Ni, Pb and Hg) by employing instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) techniques. The samples were irradiated with thermal neutrons in a nuclear reactor and the induced activities were counted by-ray spectrometry using efficiency calibrated high-resolution high purity germanium (HPGe) detector. Most of the medicinal plants were found to be rich in one or more of the elements under study. The elemental concentration in different part of medicinal plants and their biological effects on human being are discussed. It is expected that the experimental data on the elemental concentrations will be helpful in the synthesis of new Ayurvedic drugs for the control and cure of various diseases.

Background: One of the main problems of ethnomedicine, Ayurvedic system is lack of solid scientific evidence regarding safety, efficacy, quality of practices and their precise molecular mechanisms. However, many Ayurvedic preparations appear to demonstrate significant success in treatment and cure of complex diseases. Purpose: In order to develop a stronger basis for appreciating the curative effects of Ayurvedic medicinal plants, the aim of the present study was to investigate their elemental composition, which is very often overlooked in biochemical assays. Sample and Method: In the present study is applied one of the sensitive analytical techniques such as instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) to study the essential elemental content in different parts of six different Indian medicinal plants. The samples were irradiated with thermal neutrons in a nuclear reactor and the induced activities were counted by γ-ray spectrometry using efficiency calibrated high resolution High Purity Germanium (HPGe) detector. Results: The results were discussed with careful reference to established role of essential elements in the physiology and pathology of human life. The overall impact of these essential trace elements on human health is also discussed. Conclusion: The data obtained on elemental concentration of the medicinal plants studied will be useful in deciding the dosage of the Ayurvedic drugs prepared from these plant materials. The results of the present research work will be helpful to Ayurvedic clinicians and scientists who would like to pursue further research in the areas of Ayurvedic and alternative medicines.

Specific parts of several plants (fruits, leaves, stem, bark and roots) often used as medicines in the Indian Ayurvedic system have been analysed for 20 elements (As, Ba, Br, Ca, CI, Co, Cr, Cu, Fe, K, Mn, Mo, Na, P, Rb, Sb, SC, SC, Sr and Zn) by employing instrumental neutron activation analysis (INAA). The samples were irradiated with thermal neutrons in a nuclear reactor and the induced activity was counted using high resolution gamma ray spectrometry. Most of the medicinal herbs have been found to be rich in one or more of the elements under study.
