Catechin-O-Rhamnosides from Vaccinium vitis-idaea Stems

Chromatographic separation of the Me 2 CO extract of Vaccinium vitis-idaea L. (Ericaceae) stems isolated new catechin-O-glycosides that were identified using UV, IR, and NMR spectroscopy and mass spectrometry as (–)-epicatechin-3-O- α -L-rhamnopyranoside (vacciniside D, 1 ), (+)-catechin-3-O-[4′′-O-...

Zusammenfassung:Chromatographic separation of the Me 2 CO extract of Vaccinium vitis-idaea L. (Ericaceae) stems isolated new catechin-O-glycosides that were identified using UV, IR, and NMR spectroscopy and mass spectrometry as (–)-epicatechin-3-O- α -L-rhamnopyranoside (vacciniside D, 1 ), (+)-catechin-3-O-[4′′-O-(3′′′-hydroxy-3′′′-methylglutaroyl)]- α -L-rhamnopyranoside (vacciniside E, 2 ), and (+)-catechin-3-O-(2′′,4′′-di-O-galloyl)- α -L-rhamnopyranoside (vacciniside F, 3 ).
