Influence of Harvest Time on Yield and Composition of<i>Artemisia annua</i>Oil Produced in France

Abstract

ABSTRACT The essential oils of Artemisia annua were isolated and analyzed at different stages of flowering using a combination of GC and GC/MS. At the peak of flowering, the proportion of artemisia ketone (the most abundant component) exceeded 50% and the oil yield was 0.4–0.5%.
