Effects of Moquiniastrum polymorphum ssp floccosum ethnolic extract on colorectal carcinogenesis induced by 1,2-dimethylhydrazine

Genet Mol Res. 2017 Mar 16;16(1). doi: 10.4238/gmr16019518.


The objective of this study was to evaluate the effect of Moquiniastrum polymorphum ssp floccosum ethanolic extract (MPEE) on 1,2 dimethylhydrazine (DMH)-induced colorectal carcinogenesis in mice. Forty-two male Swiss mice (Mus musculus) were subdivided into six groups (N = 7/group): negative control, DMH, MPEE, pre-treatment, simultaneous, and post-treatment. Results showed that MPEE has antigenotoxic potential on the tested protocols pre- and silmultaneous treatment, and the percent damage reductions (%DRs) were 81.88 and 93.12%, respectively. The micronucleus test demonstrated that MPEE has great antimutagenic activity, with %DRs higher than 77.09 in the associated groups. The aberrant crypt focus assay demonstrated anticarcinogenic potential of MPEE as the associated groups showed %DRs that ranged from 62.13 to 95.14%. The study shows that MPEE is nontoxic and has chemopreventive and anticarcinogenic activity, thus it may prove to be a promising medicinal plant in view of its demonstrated properties.
