Abstract
Haplophyllum A. Juss. is one of the most important genus of Rutaceae family, in which over 20 species have been reported for Iran. The purpose of this study was to extract and determine essential oil composition of three Haplophyllum A. Juss. species from Kashan. Leaves of the three species i.e. H. robustum Bge., H. glaberrimum Bge. & Boiss. and H. perforatum (M. B.) Kar. & Kir. were collected from deserts and mountainous areas around Kashan. Essential oil was obtained by hydrodistillation using an all-glass Clevenger-type apparatus. The analysis of the oils was performed by using GC and GC-MS methods. The essential oil yield of H. robustum was 1.02% (v/w) and 14 components were identified. Major components of the oil were 1,8-cineol (25%), β-pinene (12.2%) and sabinene (9%). The essential oil yield of H. glaberrimum was 0/08 % (v/w) and 13 components were identified, in which the major components were myrcene (42.9%), elemole (10.6%) and β-caryophyllene (8.9%). The essential oil yield of H. perforatum was 0.38 % (v/w) and 12 components were identified, in which the major components were elemole (37.6%), β-caryophyllene (%21.1) and α-pinene (19.1%). The major components of the essential oil in H. robustum and H. glaberrimum were monoterpens, but the essential oil of H. perforatum was rich of sesquiterpenes.
