Sterols and lipids from Pleurotus florida

Chemical investigation of the dichloromethane extract of the fruiting bodies of Pleurotus floridaled to the isolation of ergosterol (1), ergosterol peroxide (2), cerevisterol(3), a mixture of palmitic acid and stearic acid, linoleic acid, and oleic acid in about 1.5:1:0.5 ratio, and dilinoleoyloleoylglycerol.
