Free Radical Scavenging Activity of Aqueous Extract of Rhus succedanea Galls

Objective: To evaluate the free radical scavenging activity of aqueous extract of Rhus succedanea galls. Material and methods: Aqueous extract was prepared and free radical scavenging activity was studied using DPPH assay and nitric oxide scavenging assay. Result: Aqueous extract of R. succedanea galls showed remarkable and concentration dependent free radical scavenging activity comparable to that of standard ascorbic acid in the studied models. IC₅₀ was found to be 27.33μg and 32.63μg in DPPH assay and NO scavenging assay respectively. Conclusion: The present results indicate that aqueous extract of R. succedanea galls exhibit free radical scavenging activity.
