Comparative quantification of flavonoid content and antioxidant potential of indigenous medicinal plants

Abstract

Medicinal plants are considered as rich sources of ingredients which can be used in drug development either pharmacopeial, non-pharmacopeial, or synthetic drugs. Some plants are considered as important sources and as result of that they are recommended for their therapeutic values. The present investigation describes the phytochemical analysis, flavonoid contents, in vitro antioxidant activity of Cissus quarangularis andMuntingia calabura plant extracts. The flavonoid content was estimated by spectrophotometric method & antioxidant propertyof aqueous & alcoholic extracts of these plants estimated by % Hydrogen Peroxide (H2O2) scavenging activity. Ethanolic extract of Muntingia calabura leaves revealed the presence of high flavonoid content. All extracts showed significant antioxidant activity in correlation to phytoconstituents of the extracts. Results showed that the ethanolic and aqueous extract of Cissus quadrangularis exhibited a higher antioxidant activity as compared toalcoholic & aqueous extract of Muntingia calabura.
