摘要: Zusammenfassung In den Wurzeln von Solanum sisymbriifolium wurde ein mit Cholesterin nicht fallbares Saponin beobachtet, das bisher unbekanntes Aglykon, Nuatigenin, enthalt. Es stellt Cholegenin-Analogon des Pflanzenreiches dar und als 22,25-Epoxy-(20S)(22S)25S)-Δ 5 -furosten-3β,27-diol erkannt. Durch Mineralsaure lagert es sich in strukturisomere Isonuatigenin, (20S)(22S)(25S)-Δ -Spirosten-3β,25-diol, um.
