The volatile compounds from various parts of Echinops ilicifolius (Compositae) such as flowers, leaves and roots obtained by hydrodistillation (HD) and headspace solid-phase microextraction (HS-SPME) methods were subsequently analysed by GC and GC/MS and compared. Thirty-seven and 20 components of the flower of E. ilicifolius were characterized, representing 99.7% and 100.0% of the total compos...

the seeds of three eucalyptus species (myrtaceae) (origin: australia), including:, eucalyptus loxophleba benth., eucalyptus microtheca f.muell.  and eucalyptus largiflorens f.muell. were cultivated in 1993-1994 at two research stations (shushtar and dezful) in khuzistan province (western south region of iran) and a research station (kashan) in isfahan province (central region of iran). these sp...

The aim of our study was to understand functional significance of spontaneous oscillations of local field potential in the olfactory brain lobe of terrestrial snail, the procerebrum (PC). We compared changes in frequency of oscillations in semi-intact preparations from snails trained to percept the same conditioned odor as positive (associated with food reinforcement) or negative (associated wi...

This study aims to investigate essential oil compositionfrom leaves and flowers of E. microthecaand E. viminalisleavesgrowing in the Southeast of Iran. Materials and Methods: The aerial parts of these plants were co...

Background & Aim: Different species from mint family (Lamiaceae) are used as spices and fragrance in food or as medicine against viral or microbial diseases in many countries for generation. Lamiaceae family contains 46 genus and 410 species. One of the valuable and medicinal species of this family is Ziziphora clinopodioides Lam. This species contains the essential o...

The composition of essential oil from the rhizomes of Hedychium larsenii M. Dan & Sathish was examined by GC-FID and GC-MS techniques. 99% of the oil consisted of monoterpenoids. Sesquiterpenoids were present only in negligible quantities. Linalool and 1,8-cineole were identified as the major components. The oil showed moderate antibacterial activity against Gram-positive and Gram-negative bact...

The essential oil of the aerial parts of Lantana achyranthifolia Desf. (Verbenaceae) was examined by GC and GC-MS. Eighteen constituents were identified. Carvacrol, 1,8-cineole, isocaryophyllene, beta-bisabolene and alpha-bisabolol were found to be the major components. The oil exhibited antibacterial activity against fourteen Gram-positive and Gram-negative bacteria.

The composition of leaf and rhizome essential oils of Alpinia smithiae that grow wild in the Western Ghats of Kerala (South India) was analysed by gas chromatography. The major components were beta-caryophyllene, sabinene, myrcene and 1,8-cineole in both samples, but variation in the yield of oil as well as the major components between the two plant parts was observed.

The genus Tanacetum is one of the most important medicinal plant that contains 26 species in Iran, 12 of them are endemic. This paper reports the essential oil (EO) composition of Tanacetum polycephalum subsp. polycephalum growing wild in Iran.  Flowers and leaves were collected from different location of Azerbaijan province (Marand, Mianeh and Tabriz), hydro-distilled to produce the oils and a...

BACKGROUND Recent investigations on the antifungal properties of essential oil of Melaleuca alternifolia Cheel (Tea Tree Oil, TTO) have been performed with reference to the treatment of vaginal candidiasis. However, there is a lack of in vivo data supporting in vitro results, especially regarding the antifungal properties of TTO constituents. Thus, the aim of our study was to investigate the in...
