GC-MS Determination of Components of Volatile Oil in Folia Artemisiae Argyi

The sample of folia artemisiae argyi was extracted by steam distillation, components of the volatile essential oil were separated and identified by GC-MS, and their relative contents (in %) were found by the method of normalization. Totally 76 compounds were separated, among which 59 compounds were identified and determined, amounting to 94.3% of the total peak areas of the components of the volatile oil. The main compounds found with their relative contents were as follows: 1,8-cineole (22.19%), camphor (10.39%), viridiflorol (6.57%), artemisia alcohol (4.95%), L-borneol (4.88%), α-terpinolene (3.98%), artemisia ketone (3.44%), (z)-sabinene hydrate (3.36%), 4-terpineol (2.68%), chrysanthenone(2.51%), β-thujone (2.41%), 1-terpineol (2.32%)and eugenol (2.26%).
