ABSTRACT
Objective:
To study the chemical constituents of flavonoids from Glycyrrhizae Radix et Rhizoma.Methods:
The compounds were isolated and purified by column chromatography over HP-20 macroporous resin, silica gel, Sephadex LH-20, and preparative RP-HPLC. Their structures were elucidated by physicochemical properties and spectral analyses.Results:
Ten flavonoids were isolated and identified as 4’,6,7-trihydroxy-2’-methoxyl-chalcone (1), 3’,4’,5,7-tetrahydroxy-8-(3-hydroxy-3- methylbutyl)-isoflavone (2), isoliquiritigenin (3), isoliquiritin (4), echinatin (5), orobol (6), ononin (7), 2(S)-3’,5’,7-trihydroxy- flavanone (8), 2(S)-naringenin-4’-O-β-D-glucopyranoside (9), and 4’,7-dihydroxyflavone (10).Conclusion:
Compounds 1 and 2 are new compounds named isolicochalcone B and licoisoflavone G, while compound 9 is isolated from the genus for the first time.
