Analysis of functional groups in selected species of the tribe Paniceae (Panicoideae, Poaceae) using FTIR spectroscopy

Fourier Transform Infrared (FTIR) spectroscopy was employed to identify and characterize the functional groups in six species from the Paniceae tribe.The FTIR spectra were obtained within the 4000-400 cm -1 range, associated with various functional groups' stretching vibrations.This study presents preliminary data on the characteristic peaks corresponding to the functional groups of six plant species, namely Pennisetum glaucum, Panicum miliaceum, Panicum sumatrense, Paspalum scrobiculatum, Setaria italica, and Echinochloa frumentacea, using caryopsis as the sample.The FTIR analysis confirmed the presence of acids, alcohols, alkanes, alkenes, carboxyl groups, halogenated compounds, and aromatic compounds in the powdered samples.The findings suggest that the caryopsis of the selected species from the Paniceae tribe contains significant bioactive compounds that may contribute to their pharmacological properties.
