Ma. Bos et al., PROCYANIDINS FROM TORMENTIL - ANTIOXIDANT PROPERTIES TOWARDS LIPOPEROXIDATION AND ANTI-ELASTASE ACTIVITY, Biological & pharmaceutical bulletin, 19(1), 1996, pp. 146-148
Procyanidins extracted from the rhizomes of Potentilla tormentilla wer
e fractionated according to their degree of polymerization by chromato
graphy on Sephadex LH20(R). Dimers and trimers displayed the highest a
nti-radical activity towards lipoperoxidation. Pentamers and hexamers
possessed the most marked anti-elastase properties.
