Abstract

Two new 3-oxo-α-ionol glucoside isomers, (6R,9R)-3-oxo-α-ionol-9-O-β-D-glucopyranosyl (1 → 2)-β-D-glucopyranoside (1) and (6S,9R)-3-oxo-α-ionol-9-O-β-D-glucopyranosyl (1 → 2)-β-D-glucopyranoside (2) were isolated from the aerial parts of Urtica laetevirens Maxim. Their structures, including stereochemistry, were established by spectral analyses (HR-ESI-MS, NMR and CD). Also, 3-oxo-α-ionol glucosides were isolated from Urtica species for the first time.
