abstract volatile constituents of the aerial parts of fresh white sage (salvia apiana jepson) were isolated by extraction with diethyl ether followed by high vacuum distillation with a solvent assisted favor evaporation (safe) apparatus. the isolated volatiles were analyzed by gc and gc/ms. a total of 84 constituents were identifed (constituting 95.1% of the total area), 11 of which were tentatively identifed. the volatiles were characterized by a high content of hydrocarbon and oxygenated monoterpenes. the major constituents identifed were 1,8-cineole (34.5%), camphor (21.7%), -pinene (7.4%), -pinene (6.4%), -3-carene (6.4%), camphene (3.9%), limonene (3.5%), myrcene (3.2%), and terpinolene (1.3%). key word index: salvia apiana white sagelamiaceaeessential oil composition1,8-cineolecamphor1,3,5-undecatriene isomers1,3,5,8-undecatetraene isomers.
