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.
