Resumo (PT): 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. <br> <br> Keywords: Tronchuda cabbage; Brassica oleracea L. var. costata DC; DPPH; Superoxide radical; Hydroxyl radical; Hypochlorous acid; Phenolics; Organic acids <br> <a target="_blank" href="http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6T6R-4GWC297-7&_user=2460038&_coverDate=12%2F31%2F2006&_rdoc=4&_fmt=high&_orig=browse&_srch=doc-info(%23toc%235037%232006%23999019996%23619917%23FLA%23display%23Volume)&_cdi=5037&_sort=d&_docanchor=&_ct=25&_acct=C000057398&_version=1&_urlVersion=0&_userid=2460038&md5=2e9a0a2065b35cca35c92b9eccec2185"> Texto integral</a> <br> <br>

Abstract (EN): 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.
