We determined the antimutagenicity of phenolic fractions of Terminalia arjuna (soluble and insoluble in chloroform) against two direct-acting mutagens, 4-nitro-o-phenylenediamine (NPD) and sodium azide, and against the S9-dependent mutagen 2-aminofluorene (2AF), in TA98 and TA100 tester strains of Salmonella typhimurium. We found that the phenolic fractions of T. arjuna inhibited revertants induced by the S9-dependent mutagen more remarkably than the direct-acting mutagens. Furthermore, the phenolic fractions showed maximum inhibition of 98% and 101.55%, respectively, in the pre-incubation mode of treatment against the mutations induced by 2AF. Overall, the fractions inhibited the revertants induced by S9-dependent mutagens more effectively than those induced by direct-acting mutagens. The percentage of inhibition was higher in the pre-incubation than with direct acting mutagens. The fraction insoluble in chloroform showed more inhibition than the soluble one, which corresponds to a higher polyphenol content in the insoluble fraction than in the soluble extract.
