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

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

A new saponin, O-α-D-arabinopyranosyl-(16)-O-[α-L-rhamnopyranosyl-(12)]-O-[β-D-xylopyranosyl-(13)]-β-D-glucopyranosyl arjunolate (1) was isolated from the flowers of Heteropappus biennis (LDB.) TAMAMSCH. The structure was established mainly by a

Three new bisdesmosidic triterpenoid saponins, helianthoside 1 (1), 2 (2), and 3 (3), were isolated from the flowers of Helianthus annuus L. and a new monodesmoside 4 was isolated after the cleavage of the ester-glycosidic linkages of 2 and 3. The st

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
