Fourier transform infrared (Ft-Ir) spectroscopic analysis of Nicotiana plumbaginifolia (Solanaceae)
The present study deals with the Fourier Transform Infrared (Ft-Ir) Spectroscopic analysis of Nicotiana plumbaginifolia, an ethnomedicinally important plant. The phytochemical group analysis of the plant has been performed by Ft-Ir method. Methanolic extraction of dried leaf along with dry KBr. salt has been employed in this method. FTIR spectral data indicates specific fingerprint region for the species. The results shows different frequencies, ranges from 896.90cm-1 to 3352.28cm-1, confirmed the presence of phenolics, protein, acid, alcohol, ether etc in this plant. It is also observed that the plant is rich in amino acids content. Different phytochemical groups present in the plant sample give an indication of its medicinal potency. Findings of this paper will be useful for identification, quality control of crude drugs obtained from this plant and pharmacological studies in future.
