One such compound is wood-fordin C (woodfructicosin), a dimeric hydrolysable tannin isolated from the leaves (Kadota S et al., 1990) which inhibits the enzymatic activity of topoi-somerase II more potently than adri-amycin and etoposide, alleviates the survival of PC-1 cells cultured in vitro colon 38 cells (Kuramochi-Motegi A et
