Fennel (Foeniculum vulgare Mill.) is a widespread perennial umbeliferous (Apiaceae) herb, traditionally used for medicinal purposes and human consumption. It is highly recommended for diabetes, bronchitis and chronic coughs, and for the treatment of kidney stones; some of those chronic diseases are related to the production of radical species involved in the oxidative stress. Therefore, the antioxidant potential of this herb might explain some of their empirical uses in folk medicine. This is the first time that a systematic study on different parts of fennel is performed, in order to understand differences in the antioxidant potential of shoots, leaves, steams, and inflorescences, particularly related to their composition in antioxidant compounds such as vitamins (ascorbic acid and tocopherols) and phenolics. The shoots seems to have the highest radical-scavenging activity and lipid peroxidation inhibition capacity (EC50 Values < 1.4 mg/ml), which is in agreement with the highest content in phenolics (65.85 +/- 0.74 mg/g) and ascorbic acid (570.89 +/- 0.01 mu g/g) found in this part. The shoots also revealed high concentration of tocopherols (34.54 +/- 1.28 mu g/g) and were the only part with flavonoids. (C) 2009 Elsevier Ltd. All rights reserved.
