Abstract:
:Bryonolic acid was isolated in high yield from transformed hairy root cultures of Trichosanthes kirilowii var. Japonica. Bryonolic acid exhibited cytotoxic activity to various tumor cells in vitro, independent of cell type. Normal cells such as rat hepatocytes are less sensitive to bryonolic acid. The appearance of a DNA ladder was detected in the bryonolic acid-treated HL-60RG cells, indicating that cell death triggered by bryonolic acid is due to apoptosis.
