Comparative Studies on the Constituents of a Parasitic Plant and Its Host. III. On the Constituents of Boschniakia rossica FEDTSCH. et FLEROV. (2)

Abstract

Two iridoid glucosides, namely boschnaloside (1), and boschnaside (2), (+) -pinoresinol-β-D-glucopyranoside (3), a new oligosaccharide (=β-D-glucopyranosyl (1→4) -α-L-rhamnopyranosyl- (1→3) -D- (4-O-caffeoyl) -glucopyranose) (4), and a new phenylpropanoid glycoside named rossicaside A (5) have been isolated from Boschniakia rossica FEDTSCH. et FLEROV (Orobanchaceae) and their structures have been determined.
