Effect of Oil Pollution on the Antioxidant Activity of the Methanolic Extracts of Polluted and Unpolluted Leaves of Hyptis suaveolens (L)

Hyptis suaveolens (L.) Poit, an aromatic weed known as pignut or daddoya-ta-daji in the Hausa language, has a longstanding history of usage food and medicine Kaduna state. This plant is interestingly found thriving environments with without oil pollution. In our modern industrial society, it's practically inevitable that these medicinal plants come contact contamination. largely because pipelines, often aged susceptible to corrosion illicit activities leading leakages, are scattered across urban rural settlements, influencing plants' phytochemical composition. study focused on examining if pollution alters antioxidant activity this plant. An evaluation properties methanol extracts from leaves, both polluted unpolluted areas, was carried out using 2,2-Diphenyl-1-Picrylhydrazyl-hydrate (DPPH) free radical scavenging assay. The outcomes showed have significant (p < 0.05) concentration-dependent activity. Yet, H. leaves' extract exhibited superior DPPH action compared leaves. median inhibitory concentrations (IC50) for were 35 µg/ml 20 respectively. Therefore, contamination had detrimental impact extract's capacity.
