Abstract

A new oleanane glycoside, named ranuncoside VII, was identified as 3-0-[α-L-arabinopyranosyl-(l→6)-(β-D-glucopyranosyl]-13β,28-epoxyolean-ll-ene-3β\15α,16α,21β\22α-pentol by chemical and spectroscopic studies. The aglycone structure was confirmed by hemisynthesis from R1-barrigenol. © 1995, Taylor & Francis Group, LLC. All rights reserved.

Abstract

Three new triterpenes, i.e. 3-oxo-15α,16α,21β,22α,28-pentahydroxy-Δ1,12-oleanane, 3-oxo-15α,16α,21β, 22α,28-pentahydroxy-Δ12-oleanane and 17,22-seco-3-oxo-22,23-dihydroxy-Δ12,16-oleanonic acid, have been isolated from Hydrocotyle ranunculoides. The structures have been attributed on the basis of their physical features.

Abstract

Six new oleanane glycosides, ranuncosides I–VI, have been isolated from Hydrocotyle ranunculoides. Their structures have been determined on the basis of chemical and spectroscopic studies.
