RESUMEN
In order to seak natural molecules with antiviral properties, we have evaluated the effect of 15 extracts of Moroccan plants used in traditional medicine on the proliferation of a cell line cancer cervix carrier of papillovirus type 16 [SiHa]. Evaluation of the resultes obtained which are due to inhibition of cellular growth was expressed in terms of variation of 50% inhibitory concentration [IC50] depending on the concentration of the product in correlation with its time of contact with the cells. Among the 15 tested extracts only the oily extracted Origanum compactum showed a significant decrease of the IC50 compared to the results of cidofovir used as a positive control. These results suggested the presence of one or more products responsible for the antiproliferative activity in the oily extract of Origanum compactum
