摘　　要：采用气相色谱、气相色谱—质谱联机的方法分析了健康和受杨圆蚧危害后的小青×黑杨 (Populus.pseudo -simonii×P .nigra)树皮中挥发油的化学成分。并从分离的 11个组分中鉴定出 10个组分的化学结构。健康树皮中含有的特异成分是乙基苯和对二乙苯 ,含有的主要成分是乙基苯 ,占总含量的 4 8.2 %。被害树皮中含有的特异成分是苯乙烯、苯甲醛和 2 ,5GC-MS methods have been used in the analyzing of essential oil from the bark of healthy Populus pseudo-simonii×P. nigra Trees, or from the bark damaged by Quadraspidiotus gigas (Thiem & Gerneck). Eleven kinds of compounds have been detected. The chemical structures of 10 components among those 11 have been confirmed. The specific compounds contained in the essential oil from healthy bark are ethylbenzene and para-diethylbenzene. The main component contained in this essential oil is ethylbenzene which accounts for 48.20%. The specific compounds contained in essential oil from bark which is damaged by Quadraspidiotus gigas (Thiem & Gerneck) are styrene, benzaldehyde and 2,5-dimethylbenzaldehyde.
