FTIR SPECTROSCOPIC STUDIES ON AERVA LANATA (L.) JUSS. EX SCHULT.

Abstract

Aim: The present study was aimed to identify the functional groups present in the crude powder of Aerva lanata (L.) Juss. ex Schult. stem, leaves, root and flower through FT-IR spectroscopy. Methods: FTIR method was performed on a Thermo Scientific Spectrophotometer system which was used to detect the characteristic peak values and their functional groups. Results: The results of A. lanata flower FTIR analysis confirmed the presence of amide, alcohols, phenols, alkanes, carboxylic acids, aldehydes, ketones, alkenes, primary amines, aromatics, esters, ethers, alkyl halides and aliphatic amines compounds which shows major peaks at 3675.36, 3618.49, 3587.12, 2918.08, 2849.76, 1771.81, 1733.59, 1652.96, 1636.03, 1457.06, 1318.57, 1243.66, 1053.77 and 510.63 respectively. The leaves of A. lanata FTIR analysis results proved the presence of alcohols, phenols, alkanes, carboxylic acids, aldehydes, alkenes, nitro compounds, alcohols, carboxylic acids, esters, ethers, aliphatic amines and alkyl halides compounds. The FTIR analysis results of A. lanata root revealed the presence of amines, amides, alkanes, aldehydes, ketones, esters, carboxylic acids, carbonyls, alkenes, primary amines, nitro compounds, aromatics, alcohols, esters, ethers and alkyl halides compounds. The FTIR analysis results of A. lanata stem validated the presence of amide, alcohols, phenols, amines, alkanes, ketones, primary amines, nitro compounds, alcohols, carboxylic acids, esters, ethers, alkyl halides and aliphatic amines. The FTIR spectroscopic studies revealed the different characteristic peak values with various functional compounds. Conclusion: The results of the present study generated the FTIR spectrum profile for the medicinally important plant A. lanata and can be used to identify the plant in the pharmaceutical industry.
