Four flavone C-glycosides, isoorientin (1), orientin (2), vitexin (3), and isovitexin (4), were isolated from the neotropical blueberry of Anthopterus wardii, a so-called "superfruit", using antioxidant activity-guided fractionation. A dose-response relationship of compounds 1-4 was determined for their anti-inflammatory activity against interleukin-8 (IL-8) and for the inhibition of matrix metalloproteinase-1 (MMP-1) expression, an inflammatory marker for chronic obstructive pulmonary disease. The four flavone C-glycosides exhibited inhibitory activity against IL-8 production and MMP-1 expression, with compounds 1, 3, and 4 having the most potent inhibitory activities in both assays at 100 μg/ml. The structures of compounds 1-4 were determined by spectroscopic methods. These flavone C-glycosides are reported for the first time in the Anthopterus genus.
