Four new steroidal oligoglycosides, named cynanchoside C_1 (14), C_2 (15), E_2 (16), and caudatinoside E_2 (17) were isolated from the rhizome of Cynanchum caudatum Max. The structures of these were elucidated by the application of ^<13>C nuclear magnetic resonance spectroscopy (CMR) and chemical reactions. Two new oligosaccharides, named cynanchobiose(12) and cynanchotriose(13), and a known disaccharide, strophanthobiose(11) were isolated from hydrolysate of crude glycoside. The structures of these oligosaccharides were elucidated mainly by comparison of CMR spectra and enzymatic hydrolyses. Further, the systematic tablation and analyses of CMR spectra are reported for the principal constituents of aglycones, mono- and oligosaccharides from C. caudatum.
