    • PURPOSE: A low toxic anticancer agent composition, containing one or more specific dammarane based compounds, including novel compounds, and capable of inhibiting tumorous cells in a very small amount without damaging cells in the inhibitory concentration thereof.
      CONSTITUTION: An anticancer agent composition containing one or more of compound expressed by formula I (glu is β-D-glucopyranosyl), formula II, III or IV. The compounds expressed by formulas I WIV are found to have powerful antitumor activity in prosapogenin and sapogenin obtained by hydrolyzing dammarane based sepogenin contained in Hydrangeae serrata Seringe var. thunbergii Sugimoto. The compounds expressed by formulas I WIV are capable of inhibiting remarkably the multiplication of uterine neck cancer calls or melanoma cells, etc. in an amount of ≤10μg/ml concentration and scarcely damaging the cell in the concentration. The agent is applicable to cancers in the skin, liver and stomach, etc. The compound of formula III is a novel compound and designated as Mh-2.
