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

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 major saponins from Bellis sylvestris have been isolated and their structures determined, mainly by high-field nmr spectroscopy. One of these [2] was identical with bellissaponin BS1 from Bellis perennis, while the second is a new triterpenoid sa

Four new bisdesmosidic saponins each containing eight carbohydrate units were isolated from Solidago canadensis. GC, GC-MS, FABMS analysis and mainly the use of 2D NMR techniques allowed their identification as bayogeninglycosides (canadensissaponins

A new acylated triterpenoid saponin was obtained from the leaves of Sanicula europaea. The structure has been elucidated from NMR and MS data, and by chemical derivatisation as 21-O-[2-methylbutanoyl]-3 beta, 15 alpha, 16 alpha, 21 beta, 22 alpha, 28

A new deacylsaponin of polygalacic acid, desacylbellidioside B 4 , was obtained from the whole plants of Bellium bellidioides L. The structure has been elucidated by a general strategy involving mass spectrometry (ESI-MS, including tandem MS, and GC-

A new acylated triterpenoid saponin carrying the rare 2,3-branched glucose at C-28 of the aglycone bayogenin (2 beta, 3 beta, 23-trihydroxyolean-12-en-28-oic acid) was isolated from the whole plants of Bellium bellidioides. The structure was elucidat

A new 3,28-bisdesmosidic triterpenoid glycoside was isolated from the mixture of deacylated saponins from the aerial parts of Solidago virgaurea. The structure of virgaureasaponin 3 was determined as 3-O-beta-D-glucopyranosyl-(1----3)-beta-D-glucopyr
