ABSTRACT:
The present study envisaged to evaluate in-vitro anti oxidant activity of ethanolic and aqueous extracts of roots of Coscinium fenestratum and extracts of Embelia ribes flower, by estimating nitric oxide scavenging activity, ferric thiocynate and total reduction capacity and carrying out DPPH assay of increasing concentration of extracts and compared with ascorbic acid, in view of investigations of pharmacological activities reported, extensive chemistry and being a part of folklore medicine. Review of literature revealed paucity of reports of in- vitro study of parts and extract chosen for the study. Results revealed concentration dependent increase in nitric oxide, DPPH free radical, ferric thiocyanate inhibition / scavenging activity, and similar total reduction capacity, indicated by increase in absorbance by ethanolic and aqueous extracts of roots of Coscinium fenestratum and of Embelia ribes flower. Ethanolic extracts possess relatively higher scavenging activity than aqueous extracts. The results identifies for the first time, the ethanolic and aqueous extracts of roots of Coscinium fenestratum and extracts of Embelia ribes flower, possess in-vitro antioxidant activity.
