摘要: A pair of flavanone glucoside diastereomers, (2R)- and (2S)-eriodictyol-5-O-beta-D-glucopyranoside (1a, 1b), was successfully separated by RP-C18 high-performance liquid chromatography from Balanophora involucrata Hook. f. Some other compounds, including a pair of flavanone enantiomers, (2R)- and (2S)-eriodictyol (2a, 2b), and a pair of flavanone glucoside diastereomers, (2R)- and (2S)-eriodictyol-7-O-beta-D-glucopyranoside(3a, 3b), were separated by capillary electrophoresis from the same plant. The absolute configurations at C-2 of la and 1b were determined based on their circular dichroism spectra. Enzymatic hydrolysis of 1a and 1b by beta-D-glucosidase afforded (2R)- and (2S)-eriodictyol, respectively, which were used as the authentic standards for co-elution to determine the migration order of the enantiomers, 2a and 2b. We also report the first example of identifying the migration order of 2a and 2b and resolving the separation of 3a and 3b by capillary electrophoresis. In addition, la was unambiguously characterized for the first time by NMR spectra. (C) 2008 Elsevier B.V. All rights reserved.
