Abstract

This study explores various medicinal herbs' antioxidant capacities and polyphenolic profiles utilizing advanced voltammetric and colorimetric techniques. These herbs, including Rosemary, Cumin, Chamomile, Fennel, Juniper, and Bell Pepper, are renowned for their health benefits, primarily attributed to their high polyphenolic content. We conducted a comprehensive analysis of these herbs' chemical constituents by employing methods such as square wave voltammetry (SWV), Folin-Ciocalteu assay, and ABTS assay. The research demonstrates a strong correlation between the polyphenolic content and antioxidant activity, emphasizing the role of phenolic acids and flavonoids. These findings not only validate the traditional uses of these herbs but also contribute to understanding their potential therapeutic benefits, laying a foundation for future nutritional and pharmaceutical applications.
