The composition of the essential oils of Artemisia judaica L. from southern Israel (Negev) and from the Sinai was investigated by means of GC and GC‐MS. Artemisia ketone and artemisia alcohol were predominant in two different Negev oil types, while piperitone was the major constituent of oils of A. judaica from the Sinai. The main difference between the chemotypes is the absence of most of the artemisyl‐skeleton type compounds from the Sinai populations. Copyright © 1992 John Wiley & Sons, Ltd
