Figure 1: SOS induction factor of Keayodendron bridelioides (KB) and Monodora myristica (MM) extracts on Escherichia coli PQ37 bacteria- SOS-chromotest (a and b). The dotted line indicate a threshold (T > 1.5) beyond which sample are considered genotoxic. T < 1.5 are probably genotoxic and T > 1 are nongenotoxic. 4-nitro quinoloneoxide served as positive control. Photomicrograph of KB and MM (c and d) showing intact and open pods
