RESUMEN
Objective: This research investigated on in vitro ffree-radical scavenging property for the alcoholic extract from Pseudarthria viscida Linn. [Leguminosae]. Different antioxidant models of screening were employed
Material and methods: The alcoholic root extract of P. viscida was screened for free radical scavenging potential using 2, 2- azinobis- [3- ethyl-benzothiazoline- 6- sulphonate] [ABTS], 1, 1- diphenyl, 2- picrylhydrazyl [DPPH], superoxide and nitric oxide radicals
Results: Concentration dependent free radical scavenging activity was observed for the extract in which a concentration of 1000 micro g/ ml exhibited maximum scavenging activity against the radical cation, 2,2- azinobis- [3- ethylbenzothiazoline- 6- sulphonate] [99.41%], followed by superoxide radical using Riboflavin- Ethylene diamine tetra-acetic acid [97.60%] and the nitric oxide model [82.50%]. However, only moderate scavenging activity was observed with the 1, 1- diphenyl, 2- picryl hydrazyl radical [59.61%] at the same concentration
Conclusion: All the results of the in vitro antioxidant models of screening revealed the potent free-radical scavenging of the alcoholic root extract of Pseudarthria viscida Linn
