STUDY OF MULTIELEMENTAL CONCENTRATIONS AND NANO-MICRO STRUCTURAL MORPHOLOGY IN MYRTACEAE FAMILY MEDICINAL PLANTS BY FIELD EMISSION SCANNING ELECTRON MICROSCOPE-ENERGY DISPERSIVE X-RAY SPECTROSCOPY METHOD

Objective: The essential multielemental analysis was carried out in nano- and microscale surface morphology of two useful selected species of Myrtaceae family medicinal plants such as Eucalyptus and Guava using “field emission scanning electron microscope”–“energy dispersive X-ray spectroscopy” (FESEM-EDS). To understand the elemental analysis of medicinal plant used in Bidar, Gulbarga/Kalaburagi and Yadgir districts of the Northeast Karnataka region. 
Methods: In the present investigation, Myrtaceae family’s medicinal plants selected. The analysis of the samples were thorough nano-micro photograph obtained by using FESEM and specific weight percent of elemental concentration analyzed by EDX/EDS. 
Results: The elemental concentrations such as C, O, magnesium, Al, Si, S, Cl, K, Ca, Mn, Fe, Cu, and Zn were estimated in all the collected medicinal plants and found to be within the World Health Organization (WHO’s) recommended values. FESEM morphology indicates that fine plane irregularly shaped particles, with size an average diameter 200 nm–1 μm, are found in both plants. 
Conclusion: The Indian Traditional Medicinal Plants have been used as a potential source for general and therapeutic medicinal purposes, including as a home remedy, Ayurvedic, and herbal drugs for the treatment of different types of human diseases. The WHO established maximum permissible limits for the consumption of major, minor, and trace elements to ensure the safe uses of medicinal plants as a drug material so as to cure the diseases. The present investigation suggests that the collected medicinal plants have good alignments of secondary metabolites, functional groups, and intake of trace elements, which are useful for treatment and preparation of new Ayurvedic, herbal, and pharmaceutical drug, pellets of very small size for alignment of different diseases.
