Sterol and Lipid from Pleurotus eryngii (DC.) Quél. and Flammulina velutipes (Cuttis) Singer

Chemical investigation of the dichloromethane extracts of the fruiting bodies of Pleurotus eryngii and Flammulina velutipes led to the isolation of ergosterol (1). P. eryngii also afforded trilinolein (2), while F. velutipes also yielded triacylglycerol (3). The structures of 1-3 were identified by comparison of their NMR data with literature data
