Fourier transform-infrared analysis of vegetative parts of weed plant Parthenium hysterophorus Linn.

Infrared spectra of vegetative parts (leaf, stem and flower) of the weed plant Parthenium hysterophorus Linn. was recorded. The observed frequencies in the region 4000-400 cm(-1) have been recorded along with vibrational assignments and intensities. Probable assignments of the bands were made with respect to the components present in the samples.
