Two new triterpene glycosides, 1 and 2, together with three known ones, were isolated from roots of Acanthophyllum laxiusculumSchiman‐Czeika. The structures of the new compounds were established by extensive 1D‐ and 2D‐NMR spectroscopic experiments and MS analyses as 23‐O‐β‐D‐galactopyranosylgypsogenic acid 28‐O‐{β‐D‐glucopyranosyl‐(1→2)‐6‐O‐[4‐carboxy‐3‐hydroxy‐3‐methyl‐1‐oxobutyl]‐β‐D‐glucopyranosyl‐(1→6)}‐[...
Two new oleanane‐type triterpene saponins, afrocyclamins A and B (1 and 2, resp.), were isolated from a MeOH extract of the roots of Cyclamen africanumBoiss. & Reuter, together with three known triterpenoid saponins, lysikokianoside, deglucocyclamin I, and its dicrotalic acid derivative. The structures were elucidated, on the basis of 1D‐ and 2D‐NMR experiments and mass spectrometry as (3β,20β...
