Abstract Title:
The cytotoxic activity of Salvia officinalis L. and Rosmarinus officinalis L. Leaves extracts on human glioblastoma cell line and their antioxidant effect.
Abstract:
Background Rosmarinus officinalis L. (Rosemary) and Salvia officinalis L. (Sage) are two Mediterranean species growing spontaneously in some area in Morocco. They are used in traditional and complementary medicine to treat numerous disorders. The aim of this work was to assess the in vitro antitumoral effect of the methanolic total extract prepared from rosemary and sage on human glioblastoma cell line (42 GMBA), conjointly with their antioxidant activity. Methods The accelerated solvent extractor was used to obtain the total extract of the studied plants. The antitumor activity was performed using the microculture tetrazolium cytotoxique assay while the antioxidant effect was evaluated using the ferric reducing antioxidant power (FRAP), and the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay. Results Our results show that the total extract of R.O and S.O have a cytotoxic effect on glioblastoma but not on cortical neurons. On the other hand, the results obtained in the FRAP and DPPH tests show a dose-dependent antioxidant activity correlated with an important level of phenols and flavonoids. Conclusion Rosmarinus officinalis L. and Salvia officinalis L. were found to have an antitumoral activity which may be linked, probably, to an antioxidant process.
