ResultsThe IC50 of the ethyl acetate extract from Alocasia macrorrhiza to A549, B16, BGC-823 were 94.6, 541.9,629.5 μg·ml-1 respectively,and those of the acetone extract from Alocasia macrorrhiza to A549 and B16 40.9,438.0 μg·ml-1 respectively. But there were quite large dosages of the IC50 of the extracts of cyclohexane, benzine, ethyl alcohol and water from Alocasia macrorrhiza to all kinds of cell lines.
