A new triterpenoid saponin, together with a known saponin, was isolated from the flowers of Lonicera Japonica Thunb. Using chemical and spectroscopic methods, mainly 2D NMR technique, their structures were deduced to be 3-β-D-glucopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)-α-L-rhamnospyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin 28-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside and 3-α-L-rhamnospyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin 28-O-α-L-rhamnospyranosyl-(1→2)-[β-D-xylcopyranosyl-(1→6)]-β-D-glucopyranoside, respectively.
