Abstract
The present investigation deals with the evaluation of phenolic, flavonoid contents and antioxidant activity in leaves, stem and roots of Solanum indicum. Powdered samples of leaves, stem and roots were subjected to successive extraction with solvents of increasing polarities i.e. Ethanol, Water: Ethanol (Aqua- alcoholic) (20: 80) and Water (aqueous) using soxhlet apparatus. The results showed the maximum phenolic content (12.351±0.03%) in Aqua- alcoholic (80: 20) extract and maximum flavonoid content (38.658±0.05%) in ethanolic extract of leaves. For stem, both the maximum phenolic (11.750±0.02%) and flavonoid (2.040±0.03%) contents was found in Aqua- alcoholic (80: 20) extract. Similarly, the maximum phenolic (18.651±0.03%) and flavonoid (2.701±0.05%) contents was found in ethanolic extract of roots. The Aqua- alcoholic (80: 20) extracts for leaves and stem and ethanolic extract for roots was found to contain the maximum antioxidant activity.
