Abstract:
Two flavanone glucosides were isolated from the 80% ethanol extract of
Glycyrrhiza uralensis using various chromatographic techniques, including macroporous adsorbent resin, RP-C
18, Sephadex LH-20, MCI and preparative HPLC. On the basis of chemical properties and spectra data, these compounds were identified as (2
S)-liquiritigenin-4'-
O-
β-
D-glucopyranosyl-(1→6)-
O-
β-
D-glucopyranoside (
1), (2
R)-liquiritigenin-4'-
O-
β-
D-glucopyranosyl-(1→6)-
O-
β-
D-glucopyranoside (
2), respectively. Compounds
1 and
2 are new compounds, and their aglycones are enantiomers.
