In the present research the radial variation of the polyphenol content was assessed from various stems of currently underutilized wood species from Hungary. The content and composition of polyphenols are closely related to various wood properties (e.g. color, durability). The sapwood, sapwood/heartwood boundary and various tissues of the heartwood were investigated. The main goal of the research was to find out if there were significant differences in the polyphenol content along the radius which may also affect utilization. Underutilized hardwood species black locust (Robinia pseudoacacia L.), Pannonia poplar (Populus x euramericana cv. Pannonia) and Turkey oak (Quercus cerris L.) were investigated which are interesting for future uses and afforestation in Hungary regarding the effects of changing climatic conditions. Quantification of total polyphenol content was accomplished using the FolinCiocalteu assay. The identification and radial variation of major polyphenolic compounds was accomplished using high-performance liquid chromatography-photodiode array detection-electrospray ionisation-multistage mass spectrometry detection.
