Summary

The sterol constituents of the unsaponifiable fractions derived from the fats of Cucurbita pepo and Sinapis arvensis seeds and that of Clerodendron inerm leaves were seemingly uniform by the conventional thin-layer chromatographic methods. The mass spectra of these sterols, however, indicated that they were mixtures of several components. A study of the fragmentation behaviour was useful in indicating the number of component sterols in a given mixture and in giving information about their probable structures. The examples given illustrate the utility of mass spectrometry in the analysis of sterol mixtures.

Zusammenfassung

Im Rahmen einer Untersuchungsreihe über Pflanzenbestandteile wurden die Sterine der Samen von Cucurbita pepo und Sinapis arvensis sowie der BlÄtter von Clerodendron inerm analysiert. Bei der üblichen Dünnschichtchromatographie erwiesen sich diese Sterine scheinbar als einheitlich, wogegen die Massenspektrometrie zeigte, da\ es sich um Mischungen mit mehreren Bestandteilen handelt. Aus dem Spaltungsverfahren konnten Schlüsse gezogen werden auf die Anzahl der Bestandteile einer Mischung und ihre wahrscheinliche Struktur. Die gegebenen Beispiele zeigen die Brauchbarkeit der Massenspektrometrie für die Analyse von Steringemischen.
