Abstract
⺠An ESI investigation into the composition of sulfited quebracho proanthocyanidins. ⺠Extraction with bisulfite leads to the introduction of sulfonic acid moieties. ⺠C-4 sulfitation breaks interflavanyl bonds and reduces chain length. ⺠C-2 sulfitation opens the pyran ring and increases water solubility. ⺠A chromatographic method to separate and quantify sulfited and non-sulfited PACs.
