Growth inhibitory activity of solvent extracts of Rhazya stricta stems on NT2 cells. The cells were incubated with different concentrations for 48 h, and the cell viability was determined by the MTS assay. The percent inhibition was calculated in comparison to the vehicle control (0.01% MeOH) of two independent experiments. Abbreviations: Hexane extract of Rhazya stricta stems (RS1S Hex), chloroform extract of Rhazya stricta stems (RS1S CHCL3), ethyl acetate of Rhazya stricta stems (RS1S EtOAc), and methanol extract of Rhazya stricta stems (RS1S MeOH)
