Distribution of strophanthidin glycosides (STRO) and digitoxigenin glycosides (DIGI) in seeds and leaves of Corchorus olitorius, and in its products (powder, drink and noodle) were investigated. Both STRO and DIGI were present in all of the seeds. There was little detectable difference in content of these glycosides in the seeds with regard to the country of their origin. And these glycosides were not detected in all of the leaves and its commercial products. Analysis of STRO and DIGI in the different stages of growth of Corchorus olitorius, and the seeds of the next generation revealed that STRO and DIGI were present not only in the seeds, but also in the seed leaves and the non-maturing pods. A caution has to be exercised in harvesting leaves of Corchorus olitoriuse not to immix its seed leaves and pods in kitchen gardens.
