Procyanidins from Tormentil: Antioxidant Properties towards Lipoperoxidation and Anti-Elastase Activity.

Abstract

Procyanidins extracted from the rhizomes of Potentilla tormentilla were fractionated according to their degree of polymerization by chromatography on Sephadex LH20. Dimers and trimers displayed the highest anti-radical activity towards lipoperoxidation. Pentamers and hexamers possessed the most marked anti-elastase properties.
