Zhao, X.H., Yan, S.C., Chi, D.F, & Wen, Z.H. 2002 [Analysis of essential oil from the bark of healthy Populus pseudo-simonii x P. nigra trees by GC-MS.]. Journal of Northeast Forestry University 30(6): 18-20.

Notes: The essential oils from the bark of healthy Populus pseudo-simonii x P. nigra and bark of damaged Quadraspidiotus gigas [Diaspidiotus gigas] were analysed using GC-MS. Eleven kinds of compounds were detected. The chemical structure of the 10 out of 11 components was confirmed. The specific compounds contained in the essential oil from the healthy bark were ethylbenzene and para-diethylbenzene. The main component of the essential oil was ethylbenzene (48.20%). The specific compounds contained in the essential oil from the bark of damaged Q. gigas were styrene, benzaldehyde and 2,5-dimethylbenzaldehyde.
