Phenolic compounds of natural knotweed (Polygonum cognatum Meissn.) populations from Turkey

The phenolic compositions of two different Polygonum cognatum samples collected from the Cumra and Manisa regions of Turkey were investigated for the first time. Both tested samples were rich in different phenolic compounds, mostly rutin, isorhamnetin, and catechin. The rutin content of Cumra’s sample was relatively higher than that of Manisa’s sample. P. cognatum has potential regarding rutin content as a functional dietary food or may be used as an ingredient to enrich functional foods. Our study will contribute to the previous works performed by different researchers on P. cognatum, commonly consumed in Turkey, to reveal its beneficial properties.
