The structures of three novel saponins from Argania spinosa, named arganines G, H, and J, have been elucidated by MS and NMR techniques as 3-O-beta-D-apiofuranosyl- (1-->4)-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosylbayogenin (1), 3-O-beta-D-apiofuranosyl-(1-->4)-beta-D-glucopyranosyl-28-O-alpha- L- arabinopyranosylbayogenin (2), and 3-O-beta-D-apiofuranosyl-(1-->4)-beta-D-glucopyranosyl-28-O- [beta-D-apiofuranosyl-(1-->3)-beta-D-xylopyranosyl-(1-->4)-alpha-L - rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranosyl]bayogenin (3), respectively.
