摘要: Abstract The stembarks of Harungana madagascariensis were analyzed for their content chemical constituents, antinutrients, vitamin levels, and in vitro antioxidant properties two solvent systems. Phytochemical screening revealed higher levels alkaloids, saponins, flavonoids the methanolic (MHM) extract than dichloromethane (DCM) extract. had contents minerals, vitamins, antinutrients except K, B1, phytic acid, respectively. Antioxidant potentials stembark extracts assessed by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity, metal chelating ferric reducing power. showed a better activity (IC50=87.66±0.97 μg/mL) DPPH system. was (92.4% at 20 mg/mL), but lower control ethylenediaminetetraacetic acid (EDTA). also greater power and...
