THE constituent saponins of bulk triterpenoidal saponins of lucerne and certain other plant materials did not separate satisfactorily on paper chromatograms with various solvents used for other saponins1. It has been found that modified solvent systems or multiple development give the most promising results2. Ascending paper chromatography was more convenient ; long running times with descending paper chromatography produced streaking with many saponins. Horizontal paper electrophoresis with weak borate buffer was also used successfully.
