Prorobinetidins are a type of condensed tannins formed from robinetinidol.
They form robinetinidin when depolymerized under oxidative conditions.
Mimosa and quebracho tannins are, according to a comparative 13C NMR study of polyflavonoids, found to be predominantly profisetinidin/prorobinetidin-type tannins.
[1] Stryphnodendron adstringens ( the barbatimão), a species of legume found in Brazil, produces prorobinetinidins in its stem bark.
