| "Essential oils obtained from Angelica archangelica L. roots immediately and after storage about 2.5 months after crushing were analyzed by GC and GC MS. The dominant component in the oils from roots crushed before analysis was α-pinene (15.7-19.4%), the other major compounds being δ -3-carene (15.4-16.0%) and limonene (8.1-8.8 %) or β-phellandrene (15.4%) and δ-3-carene (14.2%), depending on the growing localities. The dominating constituent of the crushed and stored root oils was 15-pentadecanolide (7.2-14.9%). The other main constituents were coumarine osthol (5.3-8.8%) and macrocyclic lactone 13-tridecanolide (5.4-6.1%). A large part (about 70%) of monoterpene hydrocarbons was evaporated during storage from small particles of roots, while the fraction of macrocyclic lactones (14.3-25.2%) and the amounts of coumarin osthol (5.3-8.8%) increased relatively 2-5 times." \\ | "Essential oils obtained from Angelica archangelica L. roots immediately and after storage about 2.5 months after crushing were analyzed by GC and GC MS.

| "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 α-pinene (15.7-20.8%) for two localities. Other three main constituents were δ-3-carene (15.4-16.9%), limonene (8.0-9.2%), sabinene (5.0-7.5%) for the first locality, and δ-phellandrene (13.5-15.4%), δ-3-carene (13.2-14.2%) and α-phellandrene (8.0-9.1%) for the second locality. The dominant oil components in the third locality were β-phellandrene (13.8-18.5%) together with α-pinene (11.4-15.0%), δ-3-carene (10.8-11.9%), α-cymene (6.8-10.6%) and α-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." \\ | "The roots of Angelica archangelica L. were collected in three habitats (12 samples) in 1995-2002.

The importance and usefulness of GC/MS chemical fingerprinting during this study demonstrated that one sample of A. sinensis was misidentified as A.archangelica by the vendor in China. Our GC/MS profile indicated that the A.sinensis oil was rich in phthalides not in monoterpene hydrocarbons and was misidentified and was not A.archangelica as originally indicated" \\ | of the total oil.
