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.Th...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.展开更多
A new eudesmane sesquiterpene glycoside, 1α,6β-dihydroxy-5,10-bis-epi-eudesm-4(15)-ene-6-O-β-D-glucopyranoside (2), together with a known analogue compound, 1α,6β-dihydroxy-5,10-bis-epi-eudesm-3-ene-6-O-β-D-...A new eudesmane sesquiterpene glycoside, 1α,6β-dihydroxy-5,10-bis-epi-eudesm-4(15)-ene-6-O-β-D-glucopyranoside (2), together with a known analogue compound, 1α,6β-dihydroxy-5,10-bis-epi-eudesm-3-ene-6-O-β-D-glucopyranoside (1), were isolated from the roots of Parepigynumfuningense. The structure of 2 was determined by 1D and 2D NMR spectroscopy. Compound 1 was isolated from this plant for the first time.展开更多
