From: Antioxidant and free radical scavenging activity of Spondias pinnata
Nitric oxide radical scavenging assay. The nitric oxide radical scavenging activity of Spondias pinnata extract and the standard curcumin. The data represent the percentage nitric oxide inhibition. Each value represents mean ± S.D. (n = 6). ***p < 0.001 vs 0 μg/ml. IC50 = 24.48 ± 2.31 μg/ml. The IC50 value of the standard is 90.82 ± 4.75 μg/ml.
