Abstract
The essential oil isolated by steam distillation from the aerial parts of Perovskia atriplicifolia Benth. Was analyzed by capillary GC and GC/ MS. Among the 38 compounds identified, the major components were 1,8-cineole + Limonene (40.13%), a-pinene (17.87%), -3-carene (9.13%), B-pinene (6.59%), camphene (6.17%) and camphor (5.36%).
In addition, the optimum time for steam distillation was obtained by several experiments in different times. The results showed that by 35-40 min. Steam distillation more than 99% of the oil was isolated. After separation of the main oil from the water in the condensate stream, a hexane extract of the water soluble components in water (0.03%) was also analyzed by GC and GC/MS. The major, components of the water oil were camphore (42.91%), 1,8-cineole + Limonene (29.67%) and borneol (10.76%).
