A Comparative account on Antioxidant activities, Total phenolic and Flavonoid contents of Punica granatum, Carica papaya, Foeniculum vulgare, Trigonella foenum-graecum, and Urtica dioica: An in vitro Evaluation

Abstract

Antioxidant potential of aqueous extracts was determined individually and ABTS/DPPH free radicals were utilized for scoring antioxidant activities, Folin-Ciocalteau’s reagent for Total Phenolic content and aluminum chloride colorimetry method for Total Flavonoid content evaluation. Different parts of the same plant exhibited different antioxidant potential. An overall comparative account among the different parts of selected fruits, spices and herb can be stated as Punica granatum (PG) peel˃ Punica granatum pulp˃ Carica papaya (CP) peel˃ Trigonella foenum-graecum (TFG) seeds˃ Foeniculum vulgare (FV) seeds˃ Urtica dioica (UD) dried leaves˃ Carica papaya (CP) seed˃ Urtica dioica (UD) frozen leaves˃ Punica granatum (PG) seed˃ Urtica dioica (UD) fresh leaves˃ Carica papaya (CP) pulp. Thus we can conclude that different parts of the same plant can have statistically different antioxidant potential and non-conventional parts can have good antioxidant potential which can be utilized to decrease the free radicals.
