Four oligomeric procyanidins were isolated from the MeOH extracts of the leaves of Crataegus pinnatifida (Rosaceae). Investigation of collagenase and gelatinase inhibitory natural components afforded four oligomeric procyanidins. Of these, 2 and 3 exhibited collagenase inhibitory activity (IC(50)) at a concentration of less than 1 microM, and 3 showed gelatinases A and B inhibitory activity (IC(50)) at 0.4 and 2.3 microM, respectively.
