IDENTIFICATION OF FUNCTIONAL GROUPS AND CHEMICAL PROFILING OF IPOMOEA PARASITICA USING FTIR SPECTROSCOPY

The chemical profile of Ipomoea parasitica was investigated using Fourier-transform infrared (FTIR) spectroscopy to identify the functional groups present in its methanol and AgNps extracts. Leaves and stems of Ipomoea parasitica were collected from natural habitats in Andhra Pradesh, India, and subjected to Soxhlet extraction with methanol and water. The resulting extracts were analyzed using FTIR spectroscopy with potassium bromide (KBr) pellets to determine their functional group composition. The FTIR spectra revealed prominent O-H stretching peaks at 3318.90 cm-¹¹, 3292.16 cm-¹, and 3270.18 cm-¹, indicative of alcohols and phenols. C-H stretching peaks at 2943.07 cm-¹ and 2839.56 cm-¹ confirmed the presence of alkanes. The analysis also identified C=C stretching at 1634.04 cm-¹ and multiple peaks in the 1760-1400 cm-¹ range, suggesting a diverse mixture of alkenes. Additionally, C-O stretching peaks at 1207.96 cm-¹, 1153.96 cm-¹, and 1356.32 cm-¹ highlighted the presence of alcohols, carboxylic acids, esters, and ethers. C-N stretching at 1054.20 cm-¹ indicated aromatic and aliphatic amines. Peaks for C-I and carbonyl groups further elucidated the presence of Iodo compounds and carbonyl-containing compounds. The FTIR analysis underscores the diverse chemical composition of Ipomoea parasitica, with functional groups that may have significant biological and practical implications. The presence of phenolic compounds suggests potential antioxidant or antimicrobial properties, while the broad array of functional groups indicates varied biological activities. Understanding the chemical profile of Ipomoea parasitica can inform its potential applications in pharmaceuticals, agriculture, and other fields. This is the first report of identification of functional groups from Ipomoea parasitica (leaves and stem).
