Antioxidants of therapeutic relevance in COPD from the neotropical blueberry Anthopterus wardii

► Four flavones C-glycosides (1-4) were isolated for the first time from the neotropical superfruit Anthopterus wardii. ► Dose-response relationships of compounds 1-4 were determined for IL-8 and MMP-1. ► Compounds 1, 3, and 4 showed the most potent inhibitory activity in the IL-8 and MMP-1 assays at 100 μg/mL.
