Fettsäuren einiger Waldpilze

Abstract

The total lipid content and percentages of free fatty acids in the lipids of nine wood mushrooms were determined. The total lipid content varied from 9% to 16% of the dry matter. Between 15.9 and 46.5% of the total lipids consisted of free fatty acids. The fatty acid composition of the free fatty acids of six mushrooms was analyzed quantitatively. The main component of the free acids was linoleic acid, which accounted for 30.3...60.7% of the free acids.

Lipid Biochemistry of Fungi and Other Organisms

“…L. vellereus contains 53.8% C 18 , no C 18 : x ' and 14 and 22% C18:l and C18:2' respectively. L. trivialis, L. torminosus, and L. rufus contain about the same relative proportions of C 18 : l and C 18 : 2 , but L. trivialis contains 22.5% C 24 and L. torminosus contains 27.5% C 18 (Aho and Kurkela, 1978). It is not known if these differences will hold up for isolates obtained from different locations.…”

Screening of European Fungi for Antibacterial, Antifungal, Larvicidal, Molluscicidal, Antioxidant and Free-Radical Scavenging Activities and Subsequent Isolation of Bioactive Compounds

“…Linoleic acid was shown to be responsible for the molluscicidal activity, killing the snails at a concentration of 50 mg/ml. Since linoleic acid is ubiquitous in fungi, but present in very variable amounts (Aho & Kurkela, 1978;Rezanka & Mares, 1987), it is not surprising that many extracts exhibited molluscicidal activity in the screening.…”

Method Development for the Determination of Free and Esterified Sterols in Button Mushrooms (Agaricus bisporus)

“…Notes on the occurrence of free fatty acids in mushrooms vary in the literature. Holtz and Schisler only found low amounts of free fatty acids in A. bisporus lipids while large quantities (17.5% of total lipids) were reported by Aho and Kurkela in A. bisporus and other mushrooms. − While Holtz and Schisler extracted lipids with dichloromethane/methanol (which stops enzymatic reactions), Aho and Kurkela homogenized mushrooms in isopropanol, followed by extraction with dichloromethane/methanol. Our results confirm the results of Holtz and Schisler in that free fatty acids are not major native constituents of A. bisporus lipids.…”
