摘要：

Two saponins, designated as bacopaside I and II, have been isolated from Bacopa monniera Wettst. and their structures have been elucidated as 3-O-alpha -L-arabinofuranosyl-(1 -->2)-[6-O-sulphonyl-beta -D-glucopyranosyl-(1 -->3)]-alpha -L-arabinopyranosyl pseudojujubogenin (1) and 3-O-alpha -L-arabinofuranosyl-(1 -->2)-[beta -D-glucopyranosyl (1 -->3)]-beta -D-glucopyranosyl pseudojujubogenin (2) mainly on the basis of 2D NMR and other spectral analyses.
