Abstract

Micronutrient deficiencies and oxidative stress-related diseases remain major public health challenges in sub-Saharan Africa. This study evaluated the mineral composition and antioxidant properties of four Talinum species (Talinum triangulare, Talinum paniculatum, Talinum portulacifolium, and Talinum fruticosum) collected from Southwestern Nigeria. Mineral analysis was conducted using AOAC methods, while antioxidant activities were determined using DPPH, FRAP, ABTS, and total antioxidant capacity (TAC) assays. Significant interspecific variation was observed. T. paniculatum recorded the highest calcium (1.58 ± 0.01%) and iron (295.02 ± 0.04 mg/kg), whereas T. portulacifolium showed the highest potassium (3.69 ± 0.01%) and sodium (0.78 ± 0.01%). Antioxidant assays revealed that T. paniculatum exhibited the strongest activity (DPPH: 79.52 ± 0.01%; FRAP: 26.30 ± 0.06 mg/100 g; ABTS: 84.64 ± 0.03%; TAC: 22.59 ± 0.30 mg/100 g). Correlation analysis indicated strong positive associations between iron and DPPH (r = 0.908) and phosphorus and FRAP (r = 0.933). Principal component analysis explained 91.1% of total variance, with T. paniculatum emerging as compositionally superior. These findings highlight the potential of Talinum species, particularly T. paniculatum, as functional foods for dietary fortification and management of micronutrient deficiencies and oxidative stress-related diseases.
