THE FT-IR SPECTROMETRIC STUDIES OF VIBRATIONAL BANDS OF SEMECARPUS ANACARDIUM LINN.F. LEAF, STEM POWDER AND EXTRACTS

The present study was aimed to identify the functional groups present in the crude powder and extracts of Semecarpus anacardium Linn.f. leaves and stem through FT-IR spectrometry. 14 different polar and nonpolar organic solvents were used in the soxhlet extraction of the plant material. All the vibrational bands originated from different groups like C-H, C=C, C≡C, C-O, C=O, C-I, C-Cl, C-Br, C-F, >CH2, C-N, C=C-C, S-S, N-H, NO2, H-X, O-H, P-OC etc., and may be termed as key bands and can be studied for their absorption characteristics to differentiate individual plant parts like leaves, stem etc. The FT-IR analysis of leaf powder of Semecarpus anacardium proved the presence of alcohols, phenols, alkanes, alkenes, carboxylic acids, ethers, esters, aliphatic iodo compounds and polysulfides. The FT-IR analysis results of stem powder of Semecarpus anacardium revealed the presence of alcohols, phenols, alkanes, alkenes, amines, amides, aldehydes, ketones, esters, ethers carboxylic acids, nitro compounds, aliphatic iodo compounds. The FT-IR studies revealed the different characteristic peak values with various functional groups. The results of the present study generated the FT-IR spectrum profile for the medicinally important plant Semecarpus anacardium and can be used to identify the plant in the pharmaceutical
