Evaluation of anti-inflammatory and anti-oxidant potential of seed extracts of Vernonia anthelmintica.

Seeds of Vernonia anthelmintica in the form of Ethanol seed extract of Vernonia anthelmintica (EEVA), Hexane extract of Vernonia anthelmintica (HEVA) and water decoction of Vernonia anthelmintica (WDVA) were evaluated for their in-vivo anti-Inflammatory potential in carrageenan induced rat paw model. The results were compared to anti-inflammatory activity of standard drug (ibuprofen) and untreated groups. In-vitro evaluation of antioxidant potential of EEVA and HEVA were also conducted by "DPPH scavenging assay". The results of present study depicts that HEVA and EEVA in higher dose possess a strong anti-inflammatory potential as compared to standard anti-inflammatory drugs, whereas WDVA showed milder anti-inflammatory potential. DPPH assay has revealed strong anti-oxidant potential of EEVC with the percentage Radical Scavenging activity (%RSA) of 89.709 at concentrations of 500 ul as compared to standard drugs gallic acid (23.436±0.43) and acetyl salicylic acid (111.44±0.7) at concentrations of 95.95 μM. The other extract HEVC has shown to have insignificant %RSA at the concentration of 500μl. Hence the present study revealed that selected extracts of Vernonia anthelmintica exhibited significant in-vitro antioxidant and in-vivo anti-inflammatory potential.
