Neolicuroside - a New Chalcone Glycoside from the Roots of Glycyrrhiza glabra

Article abstract of DOI:10.1002/ardp.19893220305

Licuroside (1), first isolated by Litvinenko from the roots of Glycyrrhiza glabra, is not a homogeneous compound.It is separated into two isomeric glycosides 1 and 2 using modern chromatographic techniques (HPLC, LPLC).The structure of 2 is confirmed as isoliquiritigenin-4-β-D-apiofuranosyl-2''-β-D-glucopyranoside.So far 2 has not been described.The name neolicuroside is proposed.The structure of 1 is established as isoliquirtigenin-4'-β-D-apiofuranosyl-2''-β-D-glucopyranoside by spectroscopic methods.
