摘　　要：为了探讨不同方法提取西藏黑木耳中的挥发性成分的化学组成,采取水蒸气蒸馏法和有机溶剂浸提法对黑木耳的挥发性成分进行提取,并采用GC-MS方法对提取的挥发性成分进行鉴定。水蒸气蒸馏法中鉴定了61个化学成分,主要成分是棕榈酸、亚油酸等;二氯甲烷浸提法中鉴定了36个化学成分,主要成分是麦角甾醇、5,8-麦角甾二烯-3β-醇等;乙醚浸提法中鉴定了26个化学成分,主要成分是麦角甾醇、亚油酸。In order to investigate chemical compositions of volatile components from Auricularia auricular in Tibet by means of different methods and different reagents,volatile components in Auricularia auricular was extracted by steam distillation extraction and organic solvent ultrasonic extraction. The compositions of volatile components were identified by gas chromatography-mass spectroscopy（GC-MS）. Sixty-one kinds of volatile compounds were identified by using steam distillation extraction,which were palmitic acid,linoleic acid. When the volatile components were extracted by dichloromethane solvent extraction,thirty-six kinds of volatile compounds could be obtained,which were ergosterin,ergost-5,8-dien-3β-ol. When the volatile components were extracted by diethyl ether solvent extraction,twenty-six kinds of volatile compounds could be obtained,which were ergosterin,linoleic acid.
