Abstract
Different extracts of fresh vegetative and reproductive organs from Cr ataegus monogyna harvested during a whole season and from some pharmac eutical hawthorn preparations exhibit in vitro antioxidant activities using three different models of oxygen reactive species generation (su peroxide anion, hydrogen peroxide and hypochlorous acid). All the test ed samples show low IC50 values, the most efficient being fresh young leaves, fresh floral buds and pharmaceutical dried flowers. The activi ties seem to be especially bound to the total phenolic proanthocyanidi n and flavonoid contents.
