Popis: We evaluated the potential of apple to reduce inflammation. Phenolic compounds and triterpenes were analyzed in 109 apple cultivars. Total phenolics ranged from 29 to 7882 μg g(-1) of fresh weight (FW) in the flesh and from 733 to 4868 μg g(-1) FW in the skin, with flavanols including epicatechin and procyanidins as major components. Ursolic (44.7 to 3522 μg g(-1) FW) and oleanolic (47.2 to 838 μg g(-1) FW) acids dominated the skin triterpene profile. Five chemically contrasting cultivars were fractionated and their immune-modulating activity measured using two cell-based assays targeting key points in the inflammation process. Cultivars exhibiting high contents of procyanidins were the most potent at inhibiting NF-κB while triterpene-rich fractions reduced the promoter activity of the gene of TNFα. This study provides new insights into how apple genetic diversity could be used to alleviate inflammation.
