abstract the roots of angelica archangelica l. were collected in three habitats (12 samples) in 1995-2002. the oils were analyzed by gc and gc/ms. the dominant component was -pinene (15.7-20.8%) for two localities. other three main constituents were -3-carene (15.4-16.9%), limonene (8.0-9.2%), sabinene (5.0-7.5%) for the first locality, and -phel-landrene (13.5-15.4%), -3-carene (13.2-14.2%) and -phellandrene (8.0-9.1%) for the second locality. the dominant oil components in the third locality were -phellandrene (13.8-18.5%) together with -pinene (11.4-15.0%), -3-carene (10.8-11.9%), -cymene (6.8-10.6%) and -phellandrene (5.9-8.6%). the oils contained 67.3-79.9% monoterpenoids (monoterpene hydrocarbons made up 60.2-72.6%), 9.6-19.4% sesquiterpenoids, 3.9-6.3% macrocyclic lactones and 1.2-5.3% coumarin osthol. identified compounds (81 from 96) made up 91.4-99.2% of the oils.
