Abstract:
Phytochemical investigation of the rhizomes of Iris tectorum resulted in the isolation and characterization of three new apocynin derivatives, apocynin-4-O- β -D-(6′-O-syringyl)glucopyranoside (1), scrophenoside C-7-ethyl ether (2 , 3), together with a new naturally occurring compound but known by synthesis, apocynin-4-O- β -D-xylopyranoside (4), and five known ones (5–9). Their structures were elucidated on the basis of spectroscopic data interpretation.
