Figure 2From: Antioxidant activity of ethanolic extract of inflorescence of Ormenis Africana in vitro and in cell culturesMDA (A) and conjugated diene (B) levels in HEOA supplemented HeLa cell line. Cells were cultured in 25 cm2 flasks with 5 and 10 μg/ml of HEOA for 72 hours. Oxidative stress was induced by addition of Fe2+ to the cells for 1 hour at a final concentration of 100 μM. TBARs and conjugated diene (CD) were compared to untreated cells (C-), cells treated with Fe2+ alone (C-ox) and cells treated with 100 μM ascorbic acid (AA).Back to article page
