The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to test cytotoxicity of the extracts from Marchantia convoluta
against two human cancer cell lines (H1299 and HepG2). Low concentrations of theethyl acetate extract had toxic effects on HepG2 cells and inhibited H1299 cells at higher concentration. Inhibition of proliferation and induction of cell death were in a concentration-dependent. However, the petroleum ether and n-butanol extracts of Marchantia convoluta
showed no cytotoxic activity.
