New Phenylethanoid Glycosides from Bacopa monniera.

Abstract

Three new phenylethanoid glycosides, viz. monnierasides I—III (1—3) along with the known analogue plantainoside B were isolated from the glycosidic fraction of Bacopa monniera. Their structures were elucidated mainly on the basis of two dimensional (2D) NMR spectral analyses.
