Abstract

Fifteen phenolic compounds including eight new flavonoid glycosides were isolated from Tohoku licorice (a kind of commercial licorice, which is regarded as the underground part of Glycyrrhiza uralensis). The structures of the new compounds (3R)-vestitol 7-O-glucoside and acylated flavonoid glycosides (licorice-glycosides A, B, C1, C2, D1, D2 and E), were elucidated. The ¹H NMR and CD spectral data of the acylated chalcone apioglucosides suggested the existence of intramolecular stacking of the feruloyl or p-coumaroyl groups over the aglycone residue.
