Antimutagenic Compounds of White Shrimp (Litopenaeus vannamei): Isolation and Structural Elucidation

Figure 4

Antimutagenic activity of methanolic subfractions M8a, M8b, M8c, and M8d tested at different concentrations. Values are the percentage of inhibition of AFB1 (500 ng) mutagenicity in Salmonella TA98 (a) and TA100 (b) tester strains. Results are representative of three repetitions. Spontaneous revertants were 33 ± 4 and 120 ± 8 and AFB1 control (500 ng) induced 493 ± 37 and 724 ± 21 revertants/plate for TA98 and TA100, respectively. TR: number of treatment-induced revertants, AFB1R: number of aflatoxin B1-induced revertants/plate.
