Evaluación de la actividad antidiabética In vitro de plantas medicinales de uso tradicional.
Published 2018“…Was evaluated the effect of the extracts on the expression of the PPARȖ gene, only C. submontana increased the expression level of the gene significantly compared to the drug rosiglitazone. In the same way, C. submontana was the extract with the best capture capacity of the DPPH radical with an EC50 of 21.52 ± 1.75 μg/mL Taking into account the previous results it was decided to continue only with C. submontana, which is considered to be moderately toxic in the cell proliferation assay with VERO cells. …”
