Article abstract of DOI:10.1007/BF00596749

From the epigeal organs of the great march marigold (family Ranunculaceae) two triterpene glycosides, a tetra- and a pentaoside of hederagenin, have been isolated.Their chemical structures have been established by chemical methods of investigation and by 1H and 13C NMR spectroscopy.Glycoside G is hederagenin 3-O-α-L-arabinoside 28-O- 4)-O-β-D-glucopyranosyl-(1 -> 6)-β-D-glucopyranoside>.Glycoside I is hederagenin 3-O- 2)-α-L-arabinoside 28-O- 4)-O-β-D-glucopyranosyl-(1 -> 6)-β-D-glucopyranoside>.
