An investigation of the chemical constituents of lipid of Tremella fucifor- mis Berk.is the central theme of this study.The sterols,fatty acids and phospholipids are separated by recrystalliation,column chromatography and preparative thin layer chrom- atography,and their constituents are then identified by gas liquid chromatography and spe- ctral data(UV,IR,MS and NMR).The results show that sterols comprise 16.8% ergoste- rol,28.5% ergosta-5,7-dien-3β-ol and 54.7% ergost-7-en-3β-ol;fatty acids comprise 1.32%undecanoic acid,2.37% lauric acid,1.28% tridecanoic acid,0.09% myristic acid, 5.43% pentadecanoic acid,17.20% palmitic acid,3.11% stearic acid,2.37% palmitoleic acid,38.83% oleic acid and 27.98% linoleic acid;phospholipids comprise phosphatidyle- thanolamine,phosphatidylcholine phosphatidyl glycerol. phosphatidylserine and phosphati- dylinositol. Altogether there are seventeen constituents in the lipid.
