Molecules (Basel, Switzerland) 20180116 1
Choushenflavonoids A (<b>1</b>) and B (<b>2</b>), two unusual proline-containing catechin glucosides, were isolated from the roots of <i>Codonopsis pilosula</i> cultivated in a high-altitude location of Yunnan province. Their structures were determined by spectroscopic data and chemical methods. Specifically, the absolute configuration of glucose residue in <b>1</b> and <b>2</b> was assigned by acid hydrolysis followed by derivatization and gas chromatography (GC) analysis. In addition, biologic ...[more]
