Objective: Estimation of total phenol, flavonoid, and antioxidant activity of various plant parts (leaves, stem, root, flower, and fruit) of Ailanthus excelsa Roxb. methanolic extracts.Methods: Different plant parts were extracted with methanol, then the total phenol content was calculated using Folin-Ciocalteu reagent, total flavonoid content was estimated using aluminum chloride colorimetric method and the antioxidant activity was measured by 1,1-diphenyl-2-picrylhydrazyl radical assay.
Results:The highest total phenolic content 48.38 mg gallic acid equivalent [GAE]/gdw was observed in flower and lowest phenolic content in root (28.56 mg GAE/gdw). The highest total flavonoid content (21.5 mg quercetin equivalent [QE]/gdw) was found in leaf and lowest in root (1.11 mg QE/gdw). The highest radical scavenging activity was found in flower extracts with the inhibitory concentration value of 36.85 µg/ml and the lowest scavenging activity was observed in root extract that was found to be 1493.46 µg/ml.
Conclusion:According to the results of present investigation the plant showed significant antioxidant activity that can be used for medical purpose for the treatment of various diseases.
