Effect of Blueberry Anthocyanins Malvidin and Glycosides on the Antioxidant Properties in Endothelial Cells

الملخص EN

The objective of this research was to survey the antioxidant functional role of the main anthocyanins of blueberries in endothelial cells.

Changes on the reactive oxygen species (ROS), xanthine oxidase-1 (XO-1), superoxide dismutase (SOD), and heme oxygenase-1 (HO-1) in cells of malvidin and the two glycosides were investigated.

The results showed that these anthocyanins decreased the levels of ROS and XO-1 but increased the levels of SOD and HO-1.

Glycosides improved the antioxidant capacity of malvidin to a great extent.

The changes in the antioxidant properties of malvidin-3-glucoside were more pronounced than malvidin-3-galactoside.

Variation in levels of malvidin-3-glucoside and malvidin-3-galactoside had a significant impact on antioxidant properties to different extents.

It indicates that blueberries are a good resource of anthocyanins, which can protect cells from oxidative deterioration and use blueberry as a potential functional food to prevent diseases related to oxidative stress.
