the composition of essential oil isolated from achillea eriophora, achillea millefolium, achillea biebersteinii and achillea tenuifolia growing wild in the south west of iran, was analyzed.  a. eriophora, a. millefolium and a. tenuifolia essential oils were characterized by sabinene, 1, 8-cineole, terpinene-4-ol, ά –bisabolol, p-cymene, β-pinene and α-pinene. the a. biebersteinii essential oil ...

Received 10th December, 2012 Received in revised form 20, December, 2012 Accepted 5th January, 2013 Published online 31th January, 2013 Objective: To determine the mosquito larvicidal activity of leaf essential oil and their chemical constituents from Clausena anisata (Willd.) Hook. f. ex Benth. against Anopheles subpictus and Aedes albopictus. In addition, the chemical composition of the leaf ...

In the framework of the correlation between chemotaxonomy and chemical analysis studies, the chemical composition of the essential oils of four varieties of Thuja species cultivated in Poland - T. occidentalis 'globosa', T. occidentalis 'aurea', T. plicata and T. plicata 'gracialis' - were investigated by GC and GC-MS. Thirty-one compounds were identified from T. occidentalis 'globosa', represe...

The essential oils obtained by hydrodistillation from the fresh leaf and stem of Piper porphyrophyllum N.E. Br. were analyzed by GC and GC/MS. Thirty four constituents were identified in the leaf oil, while thirty eight constituents were identified in the stems oil. The most abundant components in the leaf oil included bicyclogermacrene (14.7 %), α-copaene (13.2 %) and β-phellandrene (9.5 %) wh...

Two oleogum resin essential oils (from two different seasons: fall and summer), of Boswellia spp. (collected from Somalia), were obtained by hydrodistillation and analyzed by GC-MS. Out of 147 peaks, components were identified among the two essential oils accounting for 100%, and 99.7% of the oils, respectively. The two essential oils were dominated by the 1-methoxy alkane [octyl methyl ether (...
