Abstract: Japanese knotweed (Polygonum cuspidatum) is currently appreciated as a source of resveratrol, a stilbene with exceptional potential in the management of cardiometabolic disorders and cancer. While the underground parts of plants growing in Asia are particularly researched for the extraction of resveratrol, plant populations growing in Europe have mostly received attention due to their highly invasive character. The potential use of invasive Polygonum cuspidatum is unclear. The aim of the study was to investigate invasive Japanese knotweed populations growing in Romania as a source of plant material for further research of its medicinal potential. Fourier-transform infrared spectroscopy (FTIR) and thermal analysis (TG/DSC) were employed to characterize the rhizome extract. Subsequently, the kinetic response upon treatment with DPPH was monitored as a measure of the antioxidant activity and related to the total phenolic content. The total phenolic content of the extract measured in the current study was 146.34±5.36 mg/g extract expressed as gallic acid equivalents. Our results establish a useful background for the potential inclusion of wild growing knotweed in dietary supplements and cosmetic preparations.
Keywords: Polygonum cuspidatum, FT-IR, DPPH, antioxidant, polyphenols
