Chemical structure aspects of the lignins derived from various plants were investigated,
and their adsorption capacity towards 4,15diacetoxy8(3methylbutyryloxy)12,13epoxytri
chothecen3ol (T2 mycotoxin) was estimated. Specific surface areas and characteristics of
capillaryporous structure of the lignins were determined. Correlation ratios between sorp
tion, chemical structure and preparation of the specific surface were estimated. Acidic lignin
functional groups play a key role in the adsorption of T2 mycotoxin.
Key words: lignin, T2 mycotoxin, chemical structure, specific surface area, sorption.
Lignins are high molecular weight biopolimers found
in almost any terrestrial plants species. Lignin biosyn
thesis in vivo proceeds via dehydrogenative polymeriza
tion in a system H
main monolignols are 4[(E)3hydroxyprop1enyl]2
methoxyphenol (coniferyl alcohol), 4[(E)3hydroxy
prop1enyl]2,6dimethoxyphenol (sinapic alcohol)
and 4[(E)3hydroxyprop1enyl]phenol (pcoumaryl
alcohol). Stuctures of the natural lignins are not fully
determined up to date due to extreme complexity of
their macromolecules, as well as variation between the
The most explored are lignins of coni
fers and some leaf species, whereas lignins of the other
taxon groups remain poorly investigated. According
to the latest data
spruce lignin has the structure shown
below. Lignins containing in the other plants differ
from the spruce one by set of the structural units and
intermonomer bonding, as well as number of function
Unique characteristics of the lignin structures and
their natural origin allow one to utilize them as practical
ly useful chemical products. In particular, lignins have
antioxidant, geroprotector and sorption properties.
Currently of the special relevance is the development on
their base of efficient adsorbents for the T2 mycotoxin,
chothecen3ol which exhibits teratogen, mutagen and
cancerogen effects. This mycotoxin being the secondary
metabolite of fungi of genus Fusarium
is able to accu
mulate in spiked cereal feed and constitutes a danger for
animals, and at the end of the day to humans. Previous
it was discovered, that enterosorbents on the lignin
base could be used to prevent the mycotoxicosis. However
it is not determined yet which exact type of lignins is
