Abstract

The main objective of the study is to observe the salient features exhibited by the Fourier Transform Infrared Spectroscopy. Five samples of the dried leaves and seeds of medicinal plants Ocimum sanctum, Azadirachta indica, Pongamia pinnata, Celastrus paniculatus and Embelia ribes were selected for study of their Fourier Transform Infrared Spectroscopy. The vibrational assignments, intensities and wave number of dominant peak were obtained from absorption spectra. Various functional groups like ester, alcohol, carboxylic acid, ether, aromatic etc were identified. This article attempts to reveal the use of Fourier Transform Infrared Spectroscopy and at the same time creating interest among the prospective researcher in herbal analysis and this study creates a platform to screen many bio active components to treat various diseases.
