Encyclopedia
A prorobinetidin is a type of condensed tannins formed from robinetidin.
Mimosa
and quebracho tannins are, according to a comparative 13C NMR study of polyflavonoids, found to be predominantly profisetinidin/prorobinetidin-type tannins.
Stryphnodendron adstringens
( the barbatimão), a species of legume found in Brazil, produces prorobinetinidins in its stem bark. These are robinetinidol-(4β → 8)-epigallocatechin, robinetinidol-(4α → 8)-epigallocatechin, robinetinidol-(4β → 8)-epigallocatechin 3-O-gallate, robinetinidol-(4α → 8)-epigallocatechin 3-O-gallate, robinetinidol-(4α → 6)-gallocatechin and robinetinidol-(4α → 6)-epigallocatechin, in addition to the tentatively characterized, robinetinidol [4β → 6(8)]-gallocatechin and robinetinidol-(4α → 8)-gallocatechin.
