The volatile constituents of the roots of Panax ginseng C.A. Meyer have been investigated after hydrodistillation and analysed by means of different analytical methods. Besides several compounds already known three sesquiterpene hydrocarbons have been isolated from the essential oil. Structure elucidation of the bicyclic panaxene as well as of the tricyclic panaginsene and ginsinsene was performed by MS and NMR. They have been identified as (1R*,2S*,5S*)-2-ethenyl-1(1-methylethenyl)-2,6,6-trimethylbicyclo[3.2.0]heptane (panaxene), (1S*,8S*,11R*)-4,7,7,11-tetramethyltricyclo[6.3.0.0(1,5)]undec-4-ene (panaginsene) und (1R*,6R*,7R*)-3,7,10,10-tetramethyltricyclo[4.3.2.0(2,6)]undec-2-ene (ginsinsene).
对人参（Panax ginseng C.A. Meyer）根的挥发性成分进行了水蒸馏后研究，并采用不同分析方法进行分析。除了几种已知化合物外，还从精油中分离出三种倍半萜烃。通过质谱（MS）和核磁共振（NMR）对双环人参烯以及三环人参炔烯和人参三烯进行了结构解析。它们已被鉴定为(1R*,2S*,5S*)-2-乙烯基-1(1-甲基乙烯基)-2,6,6-三甲基双环[3.2.0]庚烷（人参烯）、(1S*,8S*,11R*)-4,7,7,11-四甲基三环[6.3.0.0(1,5)]十一碳-4-烯（人参炔烯）和(1R*,6R*,7R*)-3,7,10,10-四甲基三环[4.3.2.0(2,6)]十一碳-2-烯（人参三烯）。
