摘  要:A new 5α-adynerin-type cardenolide,named funingenoside U(1),together with its aglycone,(17R)-3β-hydroxy-4β-acetoxy-8, 14β-epoxy-5α-card-20(22)-enolide,was isolated from the roots of Parepigynumfuningense.Their structures were established on the basis of spectral(MS,1D and 2D NMR) measurements and chemical evidences.A new 5α-adynerin-type cardenolide,named funingenoside U(1),together with its aglycone,(17R)-3β-hydroxy-4β-acetoxy-8, 14β-epoxy-5α-card-20(22)-enolide,was isolated from the roots of Parepigynumfuningense.Their structures were established on the basis of spectral(MS,1D and 2D NMR) measurements and chemical evidences.
