摘要
Two flavonol glycosides, quercetin galactoside and quercetin arabinoside, have been identified in American cranberry fruit, as a complementary investigation of our previous study. The analysis processes included separation, hydrolysis and structure elucidation of flavonol glycosides. The separation of flavonol glycosides was carried out by solvent extraction, thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). After hydrolysis of the obtained flavonol glycosides, flavonol aglycones and sugars were identified by HPLC and gas chromatography-mass spectrometry (GC-MS), respectively. (c) 2006 Elsevier Ltd.
