This is first report on the composition of the leaf essential oil
of J. maritima R. P. Adams, a new juniper species from the Pacific
northwest USA. The volatile leaf oil of J. maritima is dominated by
elemicin (20.2%), sabinene (20.0%), limonene (11.7%) and 8--
acetoxyelemol (6.1%) with moderate amounts of safrole (3.8%),
pregeijerene B (3.1%) and terpinen-4-ol (1.8%). The leaf oils of J.
horizontalis, J. scopulorum and J. virginiana var. virginiana were re-
analyzed and compared with the oil of J. maritima. Each of the four
species has a distinct oil composition reflecting their specific status.
