Abstract:
Choushenosides A-C, three dimeric catechin glucosides, were isolated from the roots of Codonopsis pilosula cultivated at high elevations in Yunnan province of the People's Republic of China. The structures of these substances were determined by using spectroscopic and chemical methods. Biological evaluation showed that choushenoside C is a dose-dependent inhibitor of SIRT1.
