AbstractThe chemical composition of the leaf oils of Murraya exoticaL., Amyris balsamiferaL., Severinia buxifolia(Poir.) Ten. and Triphasia trifolia(Burm. f.) P. Wilson from Cuba were studied by GC and GC/MS. Sixty-one compounds of the oil of M. exoticawere identified of which β-caryophyllene (24.1%) was the major constituent. In the oil obtained from A. balsamifera, 56 compounds were identified of which valerianol (43.8%) was the major constituent. Sixty-seven components were identified in the oil of S. buxifoliaand the major constituents were (E)-β-santalol (26.9%) and α-santalene (22.3%), while 81 compounds were identified in the oil of T. trifoliaand the major constituent was germacrene B (16.3%).
