Abstract: By the methods of steam distillation and GC-MS,this paper analyzed the chemical components of the volatiles from withered black poplar leaves.The main components of the volatiles from young leaves were(Z)-3-hexenol(44.81%),4-methyl-1-pentanol(21.85%)and 2-hydroxy-benzaldehyde(15.19%),those from matured leaves were(Z)-3-hexenol(28.71%)and 2-hydroxy-benzaldehyde(10.35%),while in the volatiles from senescent leaves,the main components were 2-hydroxy-benzaldehyde(28.81%)and benzyl alcohol(15.06%).The(Z)-3-hexenol content in the volatiles was evidently decreased with increasing leaf age,while the species and contents of aromatic compounds were in adverse.
