Summary
The simple lipids ofSclerotium cepivorum, the causal agent of white rot of onion and nine other fungal species of the same class were investigated.
The fatty acid composition of the simple lipids of these fungi were determined by GLC. The main fatty acids common to these fungal species were C16 (saturated) and C18 (unsaturated) acids. The sterol fraction was isolated by column chromatography and its components were detected by GLC and mass spectrometry. Ergosterol and γ-Ergostenol were found mostly in all fungal species under investigation. However, two fungal species namelyAlternaria alternata andScolecobasidium constrictum showed no Ergosterol.
