Online published on 16 March, 2019. Abstract Zingiber officinale (ZO), traditionally known for its remedial potential, was examined on phytoconstituents analysis, antioxidant and xanthine oxidase inhibition by in-vitro analysis, followed by an in-silico study to identify the biological rationale. Results show that ethanolic extract of Zingiber officinale illustrated potential antioxidant to that of standard. DPPH ZO (IC50=42.09μg/mL), DPPH butylhydroxyltoluene (IC50=66.67μg/mL), nitric oxide ZO (IC50=28.36μ/mL), nitric oxide ascorbic acid (IC50=42.87μg/mL). Zingiber officinale extract inhibited the xanthine oxidase activity (IC50 = 188.5μg/mL) compared to allopurinol (IC50=499.2μg/mL), which showed competitive inhibition. The in-silico docking studies of the major phytoconstituents revealed by GC-MS analysis from this extract suggest that the inhibitory activity may be due to the combined effect of these compounds. These results suggest substantial reason for the evaluation of active compounds in in-vivo system for the management and treatment of gout as well as in the oxidative stress conditions.
