Title:
Two new 5α-adynerin-type compounds from Parepigynum funingense
Co-reporter:Yan Hua, Hai Yang Liu, Wei Ni, Chang Xiang Chen
Chinese Chemical Letters 2010 Volume 21(Issue 7) pp:846-849
Publication Date(Web):July 2010
DOI:10.1016/j.cclet.2010.03.034
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 Parepigynum funingense. Their structures were established on the basis of spectral (MS, 1D and 2D NMR) measurements and chemical evidences.
