    Composition of the essential oil from the roots of Artemisia annua
    (Springer, 2007) Goel, Divya; Goel, Richa; Singh, Vijender; Ali, Mohammed; Mallavarapu, Gopal Rao; Kumar, Sushil
    Upon hydrodistillation, dried roots of Artemisia annua L. cultivar Jwarharti gave a pleasantly fragrant essential oil with a yield of 0.25%. GC and GC–MS analyses of the oil enabled the identification of 52 components representing 83.2% of the oil. The oil was rich in sesquiterpenes and oxygenated sesquiterpenes and had cis-arteannuic alcohol (25.9%), (E)-β-farnesene (6.7%), β-maaliene (6.3%), β-caryophyllene (5.5%), caryophyllene oxide (4.4%) and 2-phenylbenzaldehyde (3.5%) as its major components. The oil was found to possess considerable fumigant activity and ability to repel adult Tribolium castaneum beetles.
