Characteristic Odor Components of Essential Oil from Dried Fruiting Bodies of Golden Oyster Mushroom (<i>Pleurotus citrinopileatus</i>)

Abstract

Abstract The components of the essential oil of Golden oyster mushroom (Pleurotus citrinopileatus) were analyzed by capillary gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). Fifty-nine components, representing 95.9% of the total oil were identified. The main components of the oil were fatty acids such as palmitic acid (23.3%), linoleic acid (31.3%) and pentadecylic acid (6.0%). Elsholtzia ketone and curcuphenol were identified in the oil of mushroom for the first time. The result of GC-O (gaschromatography olfactometry) and AEDA (Aroma Extract Dilution Analysis) showed that the sulfur and nitrogen-containing components, C8 ketone and C8 aldehyde are responsible for the aroma of P. citrinopileatus
