ABSTRACT
Moquiniastrum polymorphum subsp floccosum (Cabrera) G. Sancho is used in traditional Brazilian medicine to treat inflammation and infection, which is supported by scientific data. However, only one study has been conducted on the mutagenic activity of the extract, which has important safety implications. This study evaluated the mutagenic/antimutagenic activity of M. polymorphum ethanolic extract (MPEE) in Allium cepa meristematic cells. Commercial A. cepa seeds were cultured for 120 h. Treatments were performed for 48 h with MPEE (10 mg/mL), methyl methanesulfonate (MMS; 0.01 mg/mL), or in combination (MPEE + MMS). All of the experiments were performed in triplicate. A total of 15,000 cells per treatment were analyzed for chromosomal aberrations and the mitotic index. The results showed that MPEE was not mutagenic. In combination with MMS, MPEE decreased the number of damaged cells and the mitotic index. Interestingly, the most pronounced effect was observed post-treatment when the mitotic index also decreased, suggesting that MPEE may affect the cell cycle. MPEE exhibited antimutagenic activity, and may induce cell cycle arrest in A. cepa.
