✦ Synopsis

A new bisdesmosidic triterpene saponin, containing ten carbohydrate residues has been isolated from Solidago gigantea var. serotina. The structure was determined mainly by NMR, using selective excitation by Gau8-shaped pulses in combination with multistep relayed coherence transfer experiments.

The nature of the diuretic active principle of Solidago gigantea is still unknown', nevertheless it serves as a substitute for the pharmaceutically used Solidago virgaurea'. From the four main saponins of Solidago gigantea the most polar was isolated and its structure determined. Giganteasaponin 4 (1). is a bisdesmosidic saponin containing ten sugar residues. It
