Floral Markers of Cornflower (Centaurea cyanus) Honey andits Peroxide Antibacterial Activity for an Alternative Treatment of DigitalDermatitisJ Agric Food Chem, 2012 Nov 10Cornflower (Centaurea cyanus) honey can be characterized bya greenish-yellow color and an intensive flavor with a bitter aftertaste. Sincecornflower honey contains only a limited amount of pollen for the verificationof its floral origin, one objective was the characterization of its polyphenoland norisoprenoid content to assign floral markers. Here, lumichrome (18.8 -43.5 mg/kg), 7-carboxylumichrome, (Z/E)-3-oxo-retro-α-ionol, and 3-oxo-α-ionolappeared to be quite suitable for distinguishing cornflower honey from otherunifloral honeys. Additionally, due to its comparably high hydrogen peroxidecontent (0.5 - 0.9 mM/h) and the associated antibacterial activity, cornflowerhoney was used as an alternative treatment of digital dermatitis on an organicdairy farm. Cows affected by this hoof disease often show severe lameness, anda subsequent decline in milk yield and a loss of body condition. The cows'hoofs treated with cornflower honey showed significantly faster healing thanthe control group without any treatment.
