Comparison of phenolic content, flavonoid content and antioxidant activities of Phyllanthus emblica L. from North-East, India

The study was focused on investigating the antioxidant activity of Phyllanthus emblica fruits collected from different regions of North-East, India. The antioxidant properties of the fruit were examined using a DPPH radical scavenging test and a reducing power assay after it was extracted with methanol and ethyl acetate. There were significant variations in the total phenolic, flavonoid, and antioxidant activity depending on the population and solvent used. The phenol ranges from 57.87 (Khasi Hills) to 126.32 mg GAE/g (Garo Hills). The maximum and minimum flavonoid was between 20.14 (KRB) and 45.25 mg QE /g (LNL). The IC₅₀ of the extracts ranges between 10.67 (GH) to 42.96 (RTM).The findings highlight the considerable potential of aonla extracts from North-East India as antioxidants. Furthermore, chemical composition and biological activity of these extracts are influenced by the specific population and solvent employed in the extraction process. These results contribute to understanding of the diverse antioxidant properties of Indian gooseberry and emphasize the need for further investigation into its regional variations and optimal extraction methods.
