Elemental Profile Analysis of Some Traditional Medicinal Plants of Bangladesh Using PIXE Technique

摘要

Bangladesh is the darling child of nature where about 722 medicinal plants are available. Photosynthesis and respiration are two major reactions on which lives on the planet- earth depend. Ions of different metal element have an important role in both the reactions. Few elements are essential to the body as nutrients called minerals. Atoms of different element such as Ca, K, Mn, S, P, Mg, Fe, Si, I, Cd, Ti, V, Sc etc of Azadiracta indica , Aloe vera , Justicia adhatoda , Geodorum densiflorum , Nigella sativa , Emblica officinalis and Terminallia chebula were figured out by using PIXE ( Proton Induced X-ray Emission). Well dried pelleted samples of these medicinal plants were irradiated with proton beam accelerated with 3 MV Van de Graff accelerator. The emitted X-rays were collected using Lithium-drifted Silicon [Si(Li)] detector. Maestro and GUPIX software were used for data acquisition and analysis.
