ABSTRACT
Fifteen samples of dried leaves of medicinal values from different plants are selected for study of their FTIR spectra. The main purpose of their study is to observe the salient features exhibited by the IR spectra.All the fourteen bands originating from different groups (N-H, O-H, C-H, C=O, C=C and C=N) may be termed as key bands and one can follow their absorption characteristics and differentiate individual plant leaves or tissues. These observations also make it evident that the manifestation of bands in the infrared region results primarily from the chlorophyll molecules masking or suppressing the appearance of all other bands due to other molecular origin, which of at all appear, it does with extremely low intensities.
