IN-VITRO ANTIOXIDANT ACTIVITY OF GOSSYPIUM HERBACEUM LINN.
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2011, Vol 2, Issue 7
Abstract
The present study investigated In-vitro antioxidant activity of hydroalcoholic leaves extract (70: 30) of Gossypium herbaceum Linn. to provide scientific basis for traditional usage of this plant. The In-vitro antioxidant activity was evaluated by determining reducing power, total flavonoids and total phenolic contents using standard assay methods. The ability of the extract to scavenge 1, 1-diphenyl-2-picrylhydrazyl (DPPH) was also assessed using spectroscopic method. Ascorbic acid was used as standard antioxidant and positive control. The DPPH radical scavenging activity of the extract was increased with the increasing concentration. The IC50 values for DPPH assay of Gossypium herbaceum and ascorbic acid were found to be 44.69µg/ml and 13.80µg/ml respectively. The reducing power of the extract was found to be concentration dependent. Total flavonoid content in the extract was found to be 410 ± 0.74 mg Quercetin equivalents/g of dry material. Total phenolic content in Gossypium herbaceum was found to be 5.86 ± 0.75 mg Gallic acid equivalents/g of dry material. The results obtained from this study indicate that Gossypium herbaceum is a potential source of antioxidants and thus could prevent many radical diseases.
