in this study, a method for determining the concentration of lignin, cellulose and
hemicellulose in plant materials using Fourier-transform IR spectroscopy of Broussonetia papyrefera
was developed and tested. The procedure is based on the use of calibration functions that reflect the
dependence of the intensity of analytical absorption lines on the concentration of lignin (1512 cm-1)
and cellulose (1450 cm-1) in standard samples; indirect correlation was used for hemicellulose. The
model samples were ternary mixtures composed of lignin, bacterial cellulose and hemicellulose in
different proportions. The proposed method was tested on a wide range of plant biomass samples.
