Abstract Artemisia annua L. 'Asha' was grown in agro-climatic conditions of north Indian plains in Lucknow. The aerial parts on hydrodistillation gave 0.53% of an oil on a fresh weight basis. GC and GC/MS analysis of the oil resulted in the identification of 64 constituents, representing 95.4% of the oil. Artemisia ketone (52.9%), 1, 8-cineole (8.4%) and camphor (6.0%) were the major constituents. It is suggested that A. annua 'Asha' can be grown as an economically viable crop in the northern plains of India. Key Word Index: Artemisia annua Asteraceaeessential oil compositionartemisia ketone
