Fecha de publicación: | 15-ago-2005 | Editor: | Elsevier | Citación: | Food Chemistry 98(3): 416-425 (2006) | Resumen: | The ability of the aqueous extract of tronchuda cabbage (Brassica oleracea L. var. costata DC) external leaves to act as a scavenger of DPPH and reactive oxygen species (superoxide radical, hydroxyl radical and hypochlorous acid) was investigated. A phytochemical study was also undertaken, and thirteen phenolic compounds and five organic acids were identified and quantified. Tronchuda cabbage extracts exhibited antioxidant capacity in a concentration-dependent manner in all assays, although some pro-oxidant effect was also noticed. The samples with higher phenolic and organic acid contents displayed the major antioxidant potentials. | Descripción: | 10 pages, 6 figures, 4 tables.-- Printed version published 2006. | Versión del editor: | http://dx.doi.org/10.1016/j.foodchem.2005.06.019 | URI: | http://hdl.handle.net/10261/17834 | DOI: | 10.1016/j.foodchem.2005.06.019 | ISSN: | 0308-8146 |
