Composition of phenolic acids (PA) and total phenolics (TP) in the peat soil of the peat bog Divcibare at Maljen Mt., Serbia (Yugoslavia) has been studied at the sites where Carex stellulata Good. f. stellulata playing a significant role in the peat formation represents a dominant plant species. Overground parts of this species were found to contain p-coumaric, ferulic, vanillic and syringic acids both in the free and bound form (104.37-499.71 microgram/gram d.w.). Dry and partially decomposed residues of this plant species, as well as the peat samples from swampy and relatively dry parts of the peat bog contained all these phenolic acids but their content was much lower than in the overground parts of Carex stellulata f. stellulata. The role of phenolic acids in allelopathic interrelationship of the plants and their significance as biomarkers for paleoallelopathic studies of peat bogs with a thick peat layers was discussed. Such peat bogs represent a kind of archeological finds which preserve information on the flora, as well as on changes that have occurred during the past geological epochs.
