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

The physical and chemical indices of the fresh fruits of the two varieties were analyzed. The results showed that the sugar-acid ratio was higher in gardenblue than in baldwin, and the content of anthocyanins was also higher in gardenblue than in baldwin, so the quality of gardenblue was better. The gardenblue wine has better quality than the baldwin wine, and the two kinds of wines both have good quality. Therefore, gardenblue and baldwin both are suitable for the brewing red wine as the raw material.展开更多
