RESUMEN
The present study investigated the chemical constituents from the aerial parts of Glycyrrhiza uralensis. The ethanol extract of the aerial parts of G. uralensis was separated and purified by different column chromatographies such as macroporous resin, silica gel, and Sephadex LH-20, and through preparative HPLC and recrystallization. Thirteen compounds were isolated and identified as(2S)-6-[(Z)-3-hydroxymethyl-2-butenyl]-5,7,3'-trihydroxy-4'-methoxy-dihydroflavanone(1),(2S)-8-[(E)-3-hydroxymethyl-2-butenyl]-5,7,3',5'-tetrahydroxy-dihydroflavanone(2), α,α'-dihydro-5,4'-dihydroxy-3-acetoxy-2-isopentenylstilbene(3), 6-prenylquercetin(4), 6-prenylquercetin-3-methyl ether(5), formononetin(6), 3,3'-dimethylquercetin(7), chrysoeriol(8), diosmetin(9),(10E,12Z,14E)-9,16-dioxooctadec-10,12,14-trienoic acid(10), 5,7,3',4'-tetrahydroxy-6-prenyl-dihydroflavanone(11), naringenin(12), dibutylphthalate(13). Compounds 1-3 are new compounds, and compounds 10 and 13 are isolated from aerial parts of this plant for the first time.
