The chemical composition of the volatile constituents from the leaves, stems, and roots of Acanthopanax senticosus growing wild in Mt. Deok-Yu was determined by GC and GC/MS spectrometric analysis with the aid of NBS, Wiley Library and RI indice searches. The major constituents identified were ${delta}-elemene;(23.14%),;{eta}-elemene;(5.59%),;{gamma}-cadinene;(5.43%),;and;{alpha}-bergamotene;(28.54%)$ in the leaves, ${alpha}-pinene;(11.50%),;{delta}-elemene;(17.62%),;{alpha}-bergamotene;(27.21%)$, and bicycloheptane derivative (6.38%) in the stems, and ${alpha}-pinene;(21.90%)$, and (+)-aromadendrene (3.77%) in the roots.
