The apoptotic effects of plant sphingoid bases prepared from wheat-flour cerebroside on human colorectal cancer DLD-1 cells were examined. The viability of DLD-1 cells treated with such plant sphingoid bases was reduced in a dose-dependent manner and was similar to that of cells treated with sphingosine. Morphological changes such as condensed chromatin fragments were found, so those sphingoid bases reduced cell viability through causing apoptosis in these cells.
