Total phenolic content, flavonoid concentration and antioxidant activity of indigenous herbs, Physalis minima linn

Abstract

Physalis minima linn is a plant under the Solanaceae family having secondary metabolites with distinct biological activities. The total phenolic, total flavonoid and antioxidant activity on different parts (leaves, whole plant, stem, roots and fruits) of Physalis minima linn were analyzed using Folin-Ciocalteu method, aluminium chloride colorimetric method and 2,2'-diphenyl-1-picrylhydrazyl (DPPH) assay, respectively. Results demonstrated that leaves extract exhibited as the highest value of total phenolic content of 1125.42-14.60 mg of gallic acid (GAE) equivalent per gram of plant (dry extract). The low value of IC50 indicated that leaves, whole plant and fruits can be deemed as a good candidate for natural plant sources of antioxidants with high value of antioxidant activity.
