Summary: | Choushenflavonoids A (
) and B (
), two unusual proline-containing catechin glucosides, were isolated from the roots of
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
and
was assigned by acid hydrolysis followed by derivatization and gas chromatography (GC) analysis. In addition, biological evaluation of
and
against Sirtuin 1 (SIRT1) was carried out. |
