Eight known compounds were isolated from the shrub Tephrosia toxicaria. Among them, 6,7-dimethoxy-chromone (1), was described by the first time for this genus, villosinol (2), which had been previously reported without its 13C-NMR data and sumatrol (3), which has its 13C-NMR data corrected. The antibacterial activity of Tephrosia toxicaria extract and obovatin (6), deguelin (7), 12a-hydroxy-α-toxicarol (8), 12a-hydroxy-rotenone (10), and tephrosin (11) is also described.
