Ingia / Ingia

Eight new furostanol glycosides (1-8), together with two known ones (9 and 10), have been isolated from a glycoside-enriched fraction prepared from the rhizomes of Helleborus orientalis (Ranunculaceae). The structures of 1-8 were determined on the basis of extensive spectroscopic analysis, including

Caucasicosides E-M, furostanol glycosides from Helleborus caucasicus.

Nine furostanol glycosides, namely caucasicosides E-M, were isolated from the MeOH extract of the leaves of Helleborus caucasicus, along with 11 known compounds including nine furostanol glycosides, a bufadienolide and an ecdysteroid. Their structures were established by the extensive use of 1D and
