Abstract: Soxhlet extraction method, supercritical CO2 extraction method, microwave extraction and ultrasonic extraction were used to extract oil from ganoderma lucidum spore. The extraction ratio was 33.15%, 27.89%, 27.23% and 28.92%, respectively. Fatty acid in the obtained oil were esterified by acid method, alkali method, and the combination of the two, the samples were then analyzed by gas chromatography-mass spectrometry (GC-MS). The results indicated that the combination of acid and alkali method could identify 19 fatty acids, which was better than other esterification methods.
