Figure 3From: Antioxidant and free radical scavenging activity of Spondias pinnata Superoxide radical scavenging assay. Scavenging effect of Spondias pinnata plant extract and the standard quercetin on superoxide radical. The data represent the percentage superoxide radical inhibition. All data are expressed as mean ± S.D. (n = 6). ***p < 0.001 vs 0 μg/ml. IC50 = 13.46 ± 0.66 μg/ml. The IC50 value of the standard is 42.06 ± 1.35 μg/ml.Back to article page
