Table 3 Effect of increasing concentrations of Karapxa decoction (KD) on radical scavenging with DPP•, Nitric oxide (•NO), Superoxide, and lipid peroxidation models, compared to ascorbic acid or butylated toluene controls

From: Traditional Uighur Medicine Karapxa decoction, inhibits liver xanthine oxidase and reduces serum uric acid concentrations in hyperuricemic mice and scavenges free radicals in vitro
