Summary

The depot fat of Beauveria tenella (Delacr.) Siem. was prepared. The unesterified fatty acids totalling up to app. 1/5 of the total fat were separated and analyzed by gas-liquid chromatography. The depot fat freed from unesterified fatty acids was fractionated by column chromatography; the predominant fraction consists of triglycerides as was demonstrated by thin-layer chromatography. The position of the fatty acyl groups in the triglyceride molecules and the distribution of saturated and unsaturated fatty acyl groups on different triglyceride types were calculated from pancreatic lipase analysis results.

Zusammenfassung

Aus dem insektenpathogenen Pilz Beauveria tenella (Delacr.) Siem. wurde ein phosphatidfreies Depotfett gewonnen. Die unveresterten Fettsäuren, die etwa 1/5 des Depotfettes ausmachten, wurden abgetrennt und gaschromatographisch untersucht. Das restliche Lipid wurde säulenchromatographisch fraktioniert; die Hauptfraktion bestand aus Triglyceriden. Die Stellung der Fettsäuren im Triglyceridmolekül und die Verteilung der gesättigten und ungesättigten Fettsäuren auf die Triglycerid-Typen wurden bestimmt.
