In Vitro Antioxidant Activity of Sterculia Foetida Seed Methanol Extract

The objective of this study was to determine the phenolic content of the Sterculia foetida L. seeds methanol extract (SSME) and to evaluate the antioxidant activity of the extract. The Folin-ciocalteu procedure was used to assess the total phenolic content of the extracts as garlic acid equivalents. Antioxidant activity was evaluated using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, ferric reducing power and 2, 2-Azinobis-3-ethyl benzothiazoline-6-sulfonic acid (ABTS) diammonium salt methods. The seed methanol extract was yielded 9.5% crude material. The total polyphenol content was 14.32%. The antioxidant activity of extract was shown similar correlation between DPPH, ferric reducing power and ABTS.
