“…Barbigerone ( Figure 1A), a naturally occurring isoflavone, formally named as 2 ', 4', 5'-trimethoxy-6'', 6''-dimethylpyrano (2'', 3'': 7, 8) isoflavone, was first isolated from the seeds of Tephrosia barbigera in 1979 (Vilain, 1980) and found with minor content in species of Milletia of Leguminosae family and species of Satcolobus of Asclepiadaceae family (Yenesew et al, 1998;Wangensteen et al, 2005). This compound has exhibited profound pharmacological properties, such as antioxidant, 15-lipoxygenase inhibitory activity (Wangensteen et al, 2006), and anti-plasmodial activity (Yenesew et al, 2003).…”
