Gallotannin is almost the only polyphenol in the sapwood of Rhus succedanea L., whereas the main polyphenols in the heartwood include also fisetin, fustin, garbanzol, 3,7,4′-trihydroxyflavone, gallic and ellagic acids. Fisetin 7-glucoside is also present in small and variable amounts m the heartwood. A change in metabolism, which is one possible factor responsible for the formation of heartwood extractives, has been initiated in the sapwood of this Rhus sp. by administering enzyme inhibitors. The response to inhibitors indicates that a blockage in the utilization of acetate units in the TCA cycle may be a factor in the formation of flavonoids in the heartwood. |
