Summary

From plant material (Allium sativum, Allium cepa, Allium porrum), extracts characterised by a high haemolytic activity were obtained. In the raw saponin preparation the percentage of saponins in garlic, onion and leek was determined, applying the densitometric method on thin layer chromatograms, previously proposed5. Purified crystalline or oil-like saponin preparations were hydrolysed or complexed with cholesterol. The isolated sapogenins were identified by mass spectrometry, IR, NMR and UV analysis. The following sapogenins were found: sitosterol, gitogenin, oleanolic acid and amyrin.

Summary

Aus Allium sativum, Allium cepa und Allium porrum wurden Extrakte erhalten, die stark hämolytisch wirken. Die rohen Saponin-Präparate wurden auf Dünnschicht-Platten mit unserer densitometrischen Methode untersucht und ihr Saponingehalt bestimmt. Die gereinigten, kristallisierten oder öligen Saponinpräparate wurden einer Hydrolyse und einer Komplexierung mit Cholesterin unterzogen. Die isolierten Sapogenine wurden massenspektrometrisch, mit IR, NMR und UV geprüft. Folgende Sapogenine wurden gefunden: Sitosterol, Gitogenin, Oleanolsäure und Amyrin.
