Essential Oil Composition of Artemisia vulgaris Harvested at Different Growth Periods Under Indo-Gangetic Plain Conditions

摘要

Artemisia vulgaris was cultivated under subtropical Indo-gangetic plain conditions to determine the differences in the chemical composition of its essential oil produced from plants harvested at different growth periods using a combination of GC and GC/MS.The oil yield ranged from 0.1-0.5%.The leaf oil was found to be rich in 1,8-cineole (2.2-12.2%),alpha-thujone (0-11.4%),camphor (15.7-23.1%)an isoborneol (9.3-20.9%).The fruit oil contained alpha-thujone (15.5-16.0%)and artemisia alcohol (16.3-17.7%)as major components,while camphor (38.7%) predominated in the flower oil.
