Absolute configuration of (6S,9S)-roseoside from Polygonum hydropiper
Planta Medica
|August 8, 2001
Abstract:
From Polygonum hydropiper L., a C13-norisoprenoid glucoside was isolated and its absolute configuration was established to be (6S,9S)-roseoside (1) by spectroscopic evidence and X-ray crystallographic analysis of its acetate derivative (2). In addition, the stereostructure of roseoside from Canthium subcordatum was revised to the (6S,9S) configuration.
