Abstract
A standardised water-soluble extract was prepared from rhizomes of Pot entilla tormentilla. The procyanidins in the extract were fractionated according to their degree of polymerisation by chromatography on Seph adex LH20(R). The anti-radical activities of the different fractions t owards superoxide anion were compared,when pentamers and hexamers were found to be the most active.
