Bioactive Compounds and Antioxidant Capacity from Different Fruit Extracts of Aonla (Emblica officinalis Gaertn.)

Abstract

Aonla (Emblica officinalis Geartn.) possess significant nutraceutical properties which is distributed throughout the semi-arid region of northern Madhya Pradesh, Rajasthan, plains of Uttar Pradesh, valley of Himalayas and tropical southern part of India. Aonla is also called as Indian Gooseberry which is nutraceutical rich and also utilized in ayurvedic preparations. The study has been done to access the nutraceutical potential of Aonla from different extracts of fruit pulp powder of a local cultivar. Different extracts of fruit pulp powder i.e., in pure methanol, 80 % ethanol and Ethanol: Ethyl Acetate: Water (4:3:3) were prepared and analyzed for their bioactive compounds and antioxidant capacities. The local cultivar contains a good amount of bioactive compounds and exhibit better antioxidant capacities. Results show that the solvent of Ethanol: Ethyl Acetate: Water in ratio of 4:3:3 showed highest quantity of bioactive compounds extraction and antioxidant activity followed by 80% Ethanol in aonla. While pure methanol was found best for extraction yield and tannin content.
