摘要：The present study was carried out to evaluate the in vitro antioxidant activities of Methanol extract of Dolichos biflorus dal ( (DME) ) commonly edible food from central Himalayans . Methods: This was achieved by screening of the plant extracts at varying concentrations (20-200μg/ml), using 2,2-diphenyl-1-picryl- hydrazyl (DPPH) radical scavenging activity, reducing power assay and hydrogen peroxide radical scavenging activity. Results: Total phenol and flavonoid contents (92.10 ± 8.11 mg/ml GAE per 100 mg plant extract and 139.5 ± 55.09 mg/ml QE equivalent per 100 mg plant extract) were found respectively. Scavenging effect of DME was 4 times greater than that of the synthetic antioxidant ascorbic acid. Conclusion: Result also suggests a close relations in between total phenolic content and antioxidant activity, reducing power and radical scavenging effect on DPP H radicals, which proves Dolichos biflorus has a potential source of useful natural antioxidants.
