RESUMO
ObjectiveTo investigate the anti tumor effect of Giant Typhonium Rhizome.Methods SH-SY5Y was treated for 24 or 48 h by Giant Typhonium Rhizome.Cell Counting Kit-8 (CCK-8) cell proliferation and cytotoxicity assays were applied to detect the inhibition of SH-SY5Y cells treated with aqueous extract of white monkshood root.AV/PI double staining flow cytometry was applied to explore the mechanism of growth inhibition.ResultsSH-SY5Y cells could be inhibited by root aqueous extract of Giant Typhonium Rhizome,the IC50 at 48 h (50% inhibitory concentration) was 0.862 mg/ml,while the IC50 at 24 h was 1.158 mg/ml.Western-blot results showed that root aqueous extract of Giant Typhonium Rhizome could induce apoptosis to inhibit tumor cells.ConclusionThe Rhizoma typhonii inhibit the growth of SH-SY5Y.
