Abstract :
New antioxidants molecules especially from natural sources are of great interest today. The leaves and rhizomes of Anchomanes difformis and fruits of C. lutea were screened for the presence of chemicals constituents. The free radical scavenging activity using DPPH and total phenolic contents using Folin-Ciocalteu reagent were carried out on the ethanolic extracts of A. Difformis and C. Lutea. Both extracts of A. difformis and C. lutea were found to contain alkaloids and reductive substances. Leaves and rhizomes of A. difformis and fruits of C. lutea were found to contain (10.450.07), (21.131.11) and (4.470.27) mg of catechin/g of sample extract respectively. Fruits of C. lutea with IC50 2.02 mg/mL have showed high DPPH scavenging activity than leaves and rhizomes of Anchomanes difformis with IC50 6.49 mg/mL and 3.15 mg/mL respectively. A. diformis and C. lutea might be potential sources of bioactive phytochemicals. Further studies need to be done to isolate and to identify these chemical constituents.
