abstract = "Lignin is a poorly characterized polymer and its exact properties vary
depending on both the species of the plant and its location within the plant.
Three classes of lignins taken from alfalfa stem were examined. The investigation
was concentrated on the determination of chemical changes in the lignins
during growth and development by the attenuated total reflectance (ATR)
infrared (IR) spectrometric technique. The spectrum of permanganate lignin
was comparable to that of acid detergent lignin. The main differences were in
the different relative absorbance of the peaks. The predominant component of
acid detergent lignin and permanganate lignin was guaiacyl-type lignin. The
predominant component of Klason lignin was syringyl-type lignin. A comparison
between the signals from lignin in different development stages revealed
the appearance of new peaks, which are indications of new bonds and changes
in the structure of the lignins.",
