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.

A study was undertaken to evaluate the inorganic elements for humans in two Indian medicinal plants leaves, namely Sphaeranthus indicus, and Cassia fistula by Instrumental Neutron Activation Analysis (INAA). INAA experiment was performed by using 20 kW KAMINI Reactor at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam. The emitted gamma rays were measured using gamma ray spectrometer. The concentrations of Al, Br, Ca, Fe, K, La, Mg, Mn, Na, Sc, V and Zn were determined in the selected medicinal plants. The medicinal leaves are using in treatment of various important ailments. The elemental content in selected medicinal leaves is various proportions depending on the soil composition, location of plant specimen and the climate in which the plant grows.

Minor and trace elemental determination in the Indian herbal and other medicinal preparations
Biological Trace Element Research, 1996
Medicinal plants described in the Indian "Ayurvedic" literature viz. Tulsi (Ocimum sanctum), Gulvel (Tinospora cardifolia), bitter Neem (Azadirachta indica), Kanher (Nerium Andicum), Vekhand (Acorus calamus), and Peacock's feather (ash) were analyzed for minor and trace elements by instrumental neutron activation analysis. The samples and the standards from the National Institute of Standards and Technology, USA and IAEA, Vienna were irradiated for 5 rain, 1 h, 5 h, and 10 h with thermal neutrons at a flux of 1012-1013 n cm-2 s-1 in APSARA and CIRUS reactor at BARC, Bombay. High resolution 7 ray spectrometry was performed using a 45 cm3 HPGe detector and a 4096 MCA system. Concentrations of 13 elements were determined. Zinc, manganese, and sodium were significantly higher in Tulsi leaves while zinc is higher in Neem leaves. Peacock's feathers were found to be rich in manganese, iron, copper, and zinc. A high concentration of mercury was also found in the peacock's feather ash. The therapeutic significance in restoring ionic balance is discussed.

Determination of elements in ayurvedic medicinal plants by AAS
India has a rich country for the uses of Ayurvedic medicinal plants for treatment and also the north- Karnataka boasts an unparallel diversity of medicinal plants. The present study attempts to estimate and compare the level of trace and heavy metals in some selected leaves and root samples of Ayurvedic medicinal plants such as Mg, Al, K, Cr, Mn, Fe, Cu, Zn, and Cd. The samples are collected from different places of North-Karnataka regions and sample solutions prepared as the ratio of 1:25:25+950ml=1000ppm.the trace and heavy elemental concentration was estimated using Atomic Absorption Spectrometric (AAS) Method. The average concentrations of Mg, Mn, Fe and Zn, are ranging from 2ppm to 5250.2ppm and potassium (K) has more concentration as compare to all other. The other elements likes Al, Cr, Cu, and Cd were also estimed and presented in the table. Therefore, these medicinal plants are rich in some essential minerals, especially K, Mg, Mn, Fe and Zn which are essential for human health
CONTENT OF ELEMENTS IN AYURVEDIC MEDICINAL PLANTS ANALYZED BY USING FAAS INSTRUMENTS
In this present study total four different family medicinal plants namely Azadirachta indica, Cascabela thevetia, Ficus benghalensis and Cassia angustifolia leaves parts collected from the different places of Bidar, Kalaburagi & Yadgir districts. By using standard ratio of FAAS instruments, the solution samples for analysis of elements were prepared. Further analysis of the total 7 essential elements like Mg, Mn, Fe, Cu, Zn, As and Pb were done respectively. The Flame Atomic Absorption Spectrometer (FAAS) is analytical, or radiation source instrument and it is useful for the quantitative analysis of any materials. The average concentration of elements varied between 0.01 mg/L to 1.7 mg/L in all 4 studied Ayurvedic medicinal plants. Here Mg and Pb concentration found to be in higher range, compared to the other elements. Further all studied elemental content were found to be under the permissible limits of WHO. Results could be useful in study of metabolic, enzymatic and physical activity of the samples and also useful for the new modern medicinal preparations. The variations of elemental concentrations in environmental samples were dependents on earth geological soil formation.
