Abstrakt: | Five new cholestane glycosides, named parisfargosides A-E (1-5), were isolated from the rhizomes of Paris fargesii. Their structures were elucidated on the basis of UV, HR-ESI-MS, 1D and 2D NMR data as well as chemical methods. The structures of all compounds contained α, β-unsaturated ketone unit. Compounds 3-5 possessed a 16,23-cyclocholest skeleton with 6/6/6/5/5 condensed ring, and the absolute configurations of C-16 and C-23 were confirmed according to ROESY spectra with pyridine‑d (Copyright © 2022 Elsevier B.V.
