Показать больше [+] Меньше [-]In this study, we have found for the first time that various classes of flavonoids, namely naringenin chalcone, naringenin, dihydrotricin, and tricin, are incorporated into the lignin polymer of papyrus (Cyperus papyrus L.) rind. Identification of flavonoids was performed by analysis of the compounds released from the lignin by derivatization followed by reductive cleavage (the DFRC method), as well as by two-dimensional nuclear magnetic resonance (2D-NMR) spectroscopic analysis, and comparing with authentic standards.
