Cell viability with O. octandra treatment in OSCC cells and HEK cells. a OSCC cells were seeded in 96-well culture plates (2 × 103/well) and were treated with the indicated concentrations (50 to 300 μg/ml) of O. octandra extract for 72 h before MTT assay was performed. The extract reduced the cell viability of HSC2 and YD10B cells in a dose-dependent manner. b HEK cells were seeded into 96-well culture plates (2 × 103/well) and treated with 100 μg/ml of O.octandra extract for 72 h before MTT assay was performed (* P < 0.05, Mann whitney U test)
