Laetiporus sulphureus is a saprophyte belonging to
a specific group of wood-decomposing Basidiomycetes grow-
ing on deciduous trees. This fungus has been characterized as
a herbal medicine and is also known for its antimicrobial
properties. In the present study, high energy extraction tech-
niques using different solvents were compared to obtain max-
imum yield of the edible fungus Laetiporus sulphureus total
lipids. The lipid classes and fatty acid composition of the
fruiting bodies’ total lipids has been studied using GC-FID
and Iatroscan TLC-FID analysis. Among the lipids, the neu-
tral lipids predominated followed by phospholipids and gly-
colipids. Triglycerides were the most abundant in the neutral
lipid fraction, whereas phosphatidylcholine in phospholipids.
The existence of relatively high amount of sterols may be
correlated to fungus pharmaceutical properties. Total lipids
were found to contain high unsaturated degree fatty acids
(UFA/SFA>3.4) and dominated of C18:2ω-6, C18:1ω-9
and C16:0 fatty acids. Antibacterial and antifungal properties
of mushrooms’ lipid extracts from two different solvents were
also examined. Results indicated that hexane extracts pos-
sessed better antifungal and slightly better antibacterial activ-
ity compared to chloroform extracts though both were less
active than the commercial antimicrobial agents.
