Mutagenic Activity of Indigofera truxillensis and I. suffruticosa Aerial Parts

Table 2

Mutagenic activity expressed as the mean and SD of the number of revertants/plate in bacterial strains TA98, TA100, TA97a and TA102 exposed to MeOH extract and fractions A, B and C of I. suffruticosa, at various doses, with (+S9) or without (−S9) metabolic activation.
