Abstract
Two new triterpenoid saponins, 3-O-β-D-xylopyranosyl-(1→4)-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-β-D-arabinopyranosyloleanolic acid (1) and 3-O-β-D-xylopyranosyl-(1→4)-[α-L-arabinopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyloleanolic acid (2), were isolated and elucidated from the underground parts of Weigela x "Bristol Ruby". Their structures were established by interpretation of spectroscopic data (1 D and 2 D NMR) and mass spectrometry (MS).
