NOVEL GINSENG SAPONIN COMPOUNDS, PROCESS FOR PREPARATION THEREOF AND ANTI-TUMOR AGENT COMPRISING THE SAME AS AN ACTIVE COMPONENT

摘要

The present invention relates to novel ginseng saponin compounds having a potent anti-tumor activity, which are represented by formulae (I) and (II). The compounds (I) and (II) above are novel and can be produced by heating plants of ginseng genus for 0.5 to 20 hours at a high temperature of 110 to 180 DEG C, or can be synthesized by acetylating ginsenoside Rg3 and DELTA <20(22)>-ginsenoside Rg3 which are known ginseng saponin compounds, respectively. The present invention also relates to an anti-tumor composition comprising these compounds (I) and/or (II) as an active ingredient.
