Summary

The structures of ladyginoside D — a pentaoside of hederagenin — and of ladyginoside F — a heptaoside of hederagenin — isolated from the roots ofLadyginia bucharica have been established. The O-glycosidic carbohydrate chains of the two glycosides are identical and agree with that of ladyginoside B, corresponding to the disaccharide β-D-glucopyranosyl-(1 → 4)-β-D-glucopyranose. The acyl moiety of ladyginoside D is β-D-galactopyranosyl-(1 → 4)-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranose. In ladyginoside F, the carbohydrate chain attached to the carboxy group of the genin is branched and has the structure of [β-D-galactopyranosyl-(1 → 4)]-[β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranosyl-(1 → 6)]-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranose.
