The chemical components of the Chinese crude drug "Pai-Wei, " dried root of Cynanchum atratum BUNGE, have been further investigated. Glaucogenin-A (1), glaucoside-C (2), glaucoside-H (3) and a new glycoside named cynatratoside-F (4) were isolated. The structure of 4 was determined on the bases of spectroscopic evidence and analyses of its hydrolysate.
