Cytotoxic effect of methanol extract of wheatgrass by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and Lactate Dehydrogenase (LDH) assays at 48 h treatment (a) MTT assay shows growth inhibition (b) LDH assay shows the effect on LDH release of human laryngeal cancer cells (in vitro) by different concentration of methanol extract of wheatgrass at 48 h treatment. Values are means ± standard deviation of triplicate observations from one representative of at least three experiments with similar results
