Headspace volatiles (HS) and hydrodistilled essential oils (EO) of fresh
aerial parts of Artemisia annua L. and A. scoparia Waldst. et Kit., were
analyzed by GC-MS/FID. Artemisia ketone was found to be the most abundant
component among the EO volatiles (55.8 %), as well as among HS (52.1 %) of
A. annua. Additionally, in both A. annua samples, EO and HS, ?-pinene (12.7
and 24.2 %, respectively) was found in high percentage. On the other hand,
it has been determined that the dominant components of A. scoparia EO and HS
were different; in the essential oil capillene (63.8 %) was found as the
main constituent, while ?-pinene (26.1 %), (Z)-?-ocimene (23.8 %) and
limonene (10.7 %) were the major components among the HS. This is the first
report on the composition of HS volatiles of the A. annua and A. scoparia
obtained by direct static headspace. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. 451-03-68/2020-14/200124]
