- Abstract
Two new saponins were isolated from an ethanol extract of the whole plants of Lysimachia davuria. The new saponins were respectively characterized as 3- O-{ β-D-glucopyranosyl-(1→2)-[ β-D-glucopyranosyl-(1→4)]- α-L-arabinopyranosyl}-3 β,28-dihydroxyolean-12-en-30-oic acid- O-[ β-D-xylopyranosyl-(1→2)- β-D-glucopyranosyl]-ester ( 1) and 3- O-{ β-D-glucopyranosyl-(1→2)-[ β-D-glucopyranosyl-(1→4)]- α-L-arabinopyranosyl}-3 β,28-dihydroxyolean-12-en-30-oic acid- O- β-D-glucopyranosyl-ester ( 2). Their structures were determined by 1D, 2D NMR and MS techniques.
