Different extracts of fresh vegetative and reproductive organs from Crataegus monogyna harvested during a whole season and from some pharmaceutical hawthorn preparations exhibit in vitro antioxidant activities using three different models of oxygen reactive species generation (superoxide anion, hydrogen peroxide and hypochlorous acid). All the tested samples show low IC50 values, the most efficient being fresh young leaves, fresh floral buds and pharmaceutical dried flowers. The activities seem to be especially bound to the total phenolic proanthocyanidin and flavonoid contents.
对整个季节采集的单花山楂新鲜营养器官和生殖器官的不同提取物，以及一些药用山楂制剂，使用三种不同的活性氧生成模型（超氧阴离子、过氧化氢和次氯酸）进行体外抗氧化活性测试。所有测试样品的半数抑制浓度（IC50）值都很低，其中最新鲜的幼叶、新鲜花芽和药用干花的抗氧化活性最高。这些活性似乎尤其与总酚原花青素和类黄酮含量有关。
