Objective: This study aimed to determine the effect of mangosteen extract on hypoxia induced reactive oxygen species production and vascular endothelial growth factor (VEGF) induced retinal endothelial cell migration.Material and Method: This research studied bovine retinal endothelial cells. The non-toxic concentration of mangosteen extract of water soluble part was verified using trypan blue staining. The effects of mangosteen extract on hypoxia induced reactive oxygen species production and retinal endothelial cells migration were determined using 2’, 7’ dichlorodihydrofluorescein diacetate and scrape/wound assay, respectively. The mechanism of mangosteen extract on retinal endothelial cell migration was determined using western blotting. The analysis of variance was used to determine the differences among group means.Results: The concentrations of mangosteen extract at 25, 50 and 100 mg/ml were non-toxic and these concentrations were used in further experiments. Mangosteen extract at a dose of 100 mg/ml significantly attenuated hypoxia induced reactive oxygen species formation. At all doses, mangosteen extract also significantly inhibited retinal endothelial cell migration. However, the mechanism of mangosteen extract on VEGF signaling did not affect the phosphorylation of VEGF receptor 2 (VEGFR2).Conclusion: Mangosteen extract has anti-oxidant and anti-migration effects.
