Cytotoxic effect of Berberis libanotica roots extracts on human cancer cells and antioxidant activities
Journal Title: UNKNOWN - Year 2017, Vol 6, Issue 6
Abstract
In the present study, we evaluated the cytotoxic effect and the antioxidant activity of methanolic and ethanolic roots extracts obtained from Berberis libanotica a Lebanese medicinal tree. Cytotoxic activity was assessed on the colon cancer HT 29, HCT 116, Caco-2 and breast cancer MCF-7 and MDA-MB-231cell lines, using the MTT viability assay. Both extracts inhibited cancer cells proliferation in a doseand time depending manner without being cytotoxic against the normal MCF-10 cell line. Our results suggest that methanolic extract could induce a caspase-independent cell death in the colon and breast tumor cells HT 29 and MCF-7, respectively. DPPH and FRAP assays showed a moderate to strong antioxidant activity of the methanolic and ethanolic extracts with EC50 values of 0.13 ± 0.001 and 0.1± 0.002 mg/ml, respectively. Collectively, these findings suggest that Berberis libanotica roots could serve as a promising source of antioxidant and anticancer bioactive compounds.
