IN VITRO ANTIOXIDANT ACTIVITY ASSESSMENT OF CAPPARIS ZEYLANICA FLOWERS

This study evaluates the in vitro antioxidant activity of Capparis zeylanica flowers, emphasizing the plant’s potential as a natural source of antioxidants that can mitigate oxidative stress. Oxidative stress, driven by free radicals, is associated with chronic conditions such as cardiovascular disease, cancer, and neurodegenerative disorders. As natural antioxidants are sought to replace synthetic options with potential toxicity concerns, Capparis zeylanica offers a promising alternative, particularly due to its bioactive compounds, including phenols, flavonoids, and tannins. Fresh Capparis zeylanica flowers were extracted using a hydroalcoholic solvent, and the resulting extract was assessed through DPPH radical scavenging, ferric reducing antioxidant power (FRAP), and total phenolic content assays. The DPPH assay demonstrated moderate radical scavenging activity, while the FRAP assay revealed the extract’s reducing power, though less effective compared to standard ascorbic acid. Total phenolic content analysis confirmed the presence of significant phenolic compounds, which are key contributors to antioxidant efficacy. However, the extract’s antioxidant potency was lower than the synthetic standard, likely due to lower concentrations of phenolic compounds. The findings affirm Capparis zeylanica flowers as a moderate yet promising antioxidant source, suitable for applications in nutraceuticals and functional foods aimed at reducing oxidative stress. Given its natural origin and diverse bioactive profile, further investigations could enhance the efficacy of the extract through optimized extraction methods or isolation of specific compounds. This study supports the potential of Capparis zeylanica in antioxidant-rich supplements and underscores the need for additional research to fully understand and maximize its therapeutic applications in health preservation and disease prevention
