Abstract

|
|
This study evaluated the biological activity and cytoprotective effect of guava (Psidium guajava L.) branch againstoxidative stress. The contents of vitamin C, beta-carotene, total carotenoids, quercetin and catechin determined were26.783, 43.676, 65.083, 58.245, and 8.309 mg/100 g, respectively. To measure antioxidant activity, the guava branch wasextracted using various concentrations of ethanol (60, 80, or 100%) and water. The highest content of polyphenols (0.245mg gallic acid equivalent/mg residue) and flavonoids (0.128 mg cathechin equivalent/mg residue) was found in the 100%ethanol extract of the branch (E100). Moreover, E100 also possessed the highest radical scavenging activities and showedthe highest inhibition rate of α-glucosidase (77.692%). E100 was the most effective extract to impart cytoprotectant activityagainst oxidative stress in HepG2 cells. Taken together, our results determine the promising antioxidant activity of guavabranch, and indicate the potential to be applied as a natural antioxidant.
