An approach, using well characterized procedures, is presented that should be of general applicability for the structural elucidation of complex sugar moieties of natural products. The methods used are exemplified by the structure elucidation of a ne

Two new saponins were isolated from the seeds of Agrostemma githago L. var. githago. On the basis of chemical and spectral evidence their structures were determined to be 3-O-beta-D-xylopyranosyl-(1-->3)-[beta-D-galactopyranosyl-(1-->2)]-beta- D- glu

Seven triterpenoid saponins were isolated from both the aerial and the underground parts of Aster bellidiastrum. Five of the compounds were common to both parts. The structures were elucidated mainly from their NMR and mass spectral data, and showed

Nine saponins were isolated from the deacylated saponin mixture obtained from the whole plants of Bellis bernardii. Their structures have been elucidated from NMR and MS data and by chemical derivatization. Three were glycosides of the recently repor

Four saponins have been isolated from the herbal parts of Bellis sylvestris and the same, together with three further compounds, from the underground parts. The structures were elucidated by electrospray ionization mass spectrometry, including tandem

The structure of helianthosid 2 was re-examined by a spectroscopic investigation using one- and two-dimensional NMR spectroscopy and all 1H and 13C signals of the saccharide part were assigned. NOE difference and ROESY experiments allowed a conformat

Two new (3, 4) and two known (1, 2) genuine acylated bisdesmosidic triterpenoid glycosides of polygalacic acid (2 beta, 3 beta, 16 alpha, 23-tetrahydroxyolean-12-en-28-oic acid) were isolated from the aerial parts, as well as from the roots, of Solid

The structure of a novel saponin, possessing an unusual aglycone named bellisonic acid and isolated from whole plants of Bellis bernardii, has been elucidated by modern ms and nmr techniques as 3-O-alpha-L-rhamnopyranosyl-2 beta, 3 beta, 23-trihydrox
