Abstract. Infrared and energy dispersive X-ray spectra of plant parts (leaf, stem, and root) of the medicinal plant Eclipta alba Hassk and Eclipta prostrata Linn, was recorded. The vibrational assignments, intensities and wave number (cm^–1) of dominant peak were obtained from absorption spectra. Probable assignments of the bands were made with respect to the components present in the samples. The microphotograph obtained from scanning electron microscopy (SEM) and weight percentage of specific elemental concentration obtained from energy dispersive X-ray spectrometer attached to SEM are reported and analyzed sample wise and the results are discussed.
Key words: FT-IR spectra, SEM-EDS, Eclipta alba Hassk, Eclipta prostrata Linn, plant parts.
