The present study identified the functional Gardenblue blueberry （Vaccinium ashei Reade） anthocyanin extracts （GBBAEs） and evaluated their capacity and underlying mechanisms in protecting murine RAW 264.7 cells from lipopolysaccharide （LPS）-stimulated inflammation in vitro. Enzyme-linked immunosorbent assay （ELISA） kit results showed that GBBAEs significantly inhibited the production of nitric oxide （NO）, prostaglandin E2 （PGE2）, interleukin-6 （IL-6）, IL-113, and interferon-y （INF-y）. Real-time polymerase chain reaction （PCR） analysis in- dicated that the mRNA expression levels of IL-6, IL-113, tumor necrosis factor-α （TNF-α）, monocyte chemoattractant protein-1 （MCP-1）, and cyclooxygenase 2 （COX-2） were suppressed in LPS-stimulated RAW 264.7 cells. Additionally, Western blot analysis was used to evaluate the relative protein expression levels of COX-2 and nuclear factor-κB p65 （NF-κBp65）. All these results suggested the potential use of GBBAEs as a functional food for the treatment of in- flammatory diseases.展开更多

Fourteen anthocyanins have been identified, among them 12 are -3-O-galactosides, glucosides, and arabinosides of delphinidin, cyanidin, petunidin, and malvidin, and 2 are -3-O-galactoside and glucoside of peonidin. Another 2 anthocyanins are under elucidation. It indicated that the components of the pigment extracted from V. ashei are similar to Myrtocyan extracted from V. myrtillus L., but the ratios are different and the contents are much lower.展开更多
