Daphnetin, a natural coumarin derivative isolated from the traditional Chinese medicinal herb Daphne odora var., has been reported to show anti-inflammatory properties [8, 9, 19].
Based on the wide distribution of coumarin derivatives in plant-based foods and beverages in the human diet, our objective was to evaluate both the antioxidant and intestinal anti-inflammatory activities of six coumarin derivatives of plant origin (scopoletin, scoparone, fraxetin, 4-methyl-umbeliferone, esculin and daphnetin) to verify if potential intestinal anti-inflammatory activity was related to antioxidant properties.
Results: Treatment with esculin, scoparone and daphnetin produced the best protective effects.
