Abstract

The present invention relates to technical field of medicine, and relates to the use of diterpenoid compounds of glaucocalyxin A, glaucocalyxin B, glaucocalyxin C, glaucocalyxin D, glaucocalyxin E and glaucocalyxin F in Isodon japonica (Burm f) Hara var glaucocalyx (Max) Hara for preparing anti-cancer medicine. The invention adopts an MTT method for executing cytotoxicity experiment. The result shows that the glaucocalyxin A, glaucocalyxin B, glaucocalyxin C, glaucocalyxin D, glaucocalyxin E and glaucocalyxin F all have remarkable cytotoxicity respectively thereby can be used for preparing the anti-cancer medicine. The invention provides a new source for preparing anti-cancer medicine.
