Ceterach officinarum D.C., Asplenium trichomanes L. and A. adiantum nigrum L. occur in the
fissures of precipitous calcareous rocks in the Gorge of Sićevo. Here, humus rhizosphere soil, i.e.
Lithosol, mainly consisting of the leaf and root remains of the ferns in different degradation phases
gets formed. The present study was concentrated on determination of total phenolics in the fern
leaves, rhizomes and rhizosphere soil and on the analyses of phenolic acids. In the leaves of all
three ferns total free phenolics were dominant and exceeded that of their bound forms 1.28–6.95
times. The highest amounts of phenolics were found in the leaves (free of 11 744.00 μg g–1 and
bound of 9 135.00 μg g–1, respectively) and rhizomes (free of 2 811.11 μg g–1 and bound 1 962.74
μg g–1, respectively) of Ceterach officinarum. The humus of rhizosphere soil under the ferns was
characterized by higher amounts of total bound phenolics (up to 3 873.34 μg g–1). It contained low
amounts of free phenolic acids (0.687–9.115 μg g–1). The content of bound phenolic acids exceeded
that of their free forms up to 280 times. Since ferns as pioneer species grow at first in the rock
fissures either containing no soil or soil in the stage of formation, produces phenolic compounds
as secondary metabolites and thus play the significant role in soil and humus formation.
