Résumé
Objective: To determine the total phenolic content and in vitro xanthine oxidase inhibitory activity of methanol extracts of leaves and stem bark of Erythrina indica. Methods: Folin-ciocalteu method was used to determine the total phenolic content. Xanthine oxidase inhibitory activity was assayed spectrophotometrically and the degree of enzyme inhibition was determined by measuring the increase in absorbance at 295nm associated with uric acid formation. Results:The methanol extract of stem bark of E. indica contains higher level of total phenolic content (412.8 mg GAE/g extract) and also exhibited higher xanthine oxidase inhibition activity (IC50 52.75μg/mL) than the leaves. Conclusions: It could be concluded that the stem bark of E. indica was highly effective in xanthine oxidase inhibition and might be used for the gout related disorders.
