Item Evaluation of in-vitro antioxidant activities of methanol extracts of Persea americana and Cnidosculus aconitifolius(Pak J Nutr, 2010) Asaolu, M. F.; Asaolu, S. S.; Fakunle, Julius B.; Emman-Okon, B. O.; Ajayi, E. O.; Togun, R. A.The present study was undertaken to investigate the antioxidant activities of Persea americana and Cnidosculous aconitifolius. The in-vitro antioxidant activity of the methanol extracts of the leaves of Persea americana and Cnidosculous aconitifolius was evaluated using various experimental methods such as 1,1-diphenyl-2-picryl-hydrazyl (DPPH), nitric oxide and reducing power radical-scavenging activity assay. Phytochemical screening as well as the amounts of total phenol and flavonoids were also determined. The present study revealed that both the methanol extracts of the leaves of Persea americana and Cnidosculous aconitifolius possess significant antioxidant activities. However, Persea americana was found to have higher radical scavenging activity than Cnidosculous aconitifolius but the phenol content of Cnidosculous aconitifolius was higher than that of Persea americana whereas Persea americana was observed to possess more flavonoids than Cnidosculous aconitifolius.
