| Abstract:
|
The present study was carried out to evaluate the antioxidant activity of extracts of Boerhaavia
diffusa dried root powder (Nyctaginaceae). In evaluation, ethanol and methanol extracts were prepared
and screened for in-vitro antioxidant activities using Ferric reducing power and Hydrogen peroxide scavenging
activity. The activity was compared to standard antioxidant like ascorbic acid. Both the extract
showed strong antioxidant activity in both the methods. Between these two extracts, ethanolic extract has
shown better antioxidant activity as compared to methanolic extract in both the activities. In addition to
antioxidant activity, the total alkaloid and total tannin content was also measured. The total alkaloid and
total tannin content was found to be 0.15% and 0.52% respectively. Hence, the extract can be subjected to
detailed study as an antioxidant.
