Essential oils from three of the eleven endemic New Zealand species of Pseudopanax, P. arboreus, P. discolor and P. lessonii, were found to have a fairly uniform composition which was different from that of the oils of Raukaua species that were formerly classified in the Pseudopanax genus. Oils of the three Pseudopanax species all contained significant proportions of viridiflorol and a closely ...

OBJECTIVES Various species of genus Trigonella are important from medical and culinary points of view. The essential oil of Trigonella torbatejamensis Ranjbar as an endemic plant in Iran has not been studied previously. The essential oil of this plant was analyzed by different methods for identification of its components. MATERIALS AND METHODS The essential oil composition of aerial parts of ...

Calendula officinalis L. has been largely known for its topical anti-inflammatory properties; however, there are no experimental evidences about its antiphlogistic effect at the gastric level. To investigate whether marigold might exert an activity against gastric inflammation, a CH2Cl2 extract obtained from C. officinalis flowers was evaluated in vitro on the NF-κB pathway. The lipophilic extr...

The essential oils of fifteen Eucalyptus species harvested from the Jbel Abderrahman and Korbous arboreta (North East Tunisia) were screened for their antibacterial activities by the agar disc diffusion method. Eighteen major components as identified by GC/FID and GC/MS were selected for a study of the chemical and biological activity variability. The main one was 1,8-cineole, followed by spath...

This study examined the chemical composition of essential oil extracted from bark Alseodaphne peduncularis Meisn. (Lauraceae) by hydrodistillation with 0.2% yield. The was chemically characterised gas chromatography-flame ionization detector and chromatography-mass spectrometry, 31 constituents comprising 94.3% total content were identified. These included β-caryophyllene (24.5%), viridiflorol ...

According to distribution of genus Achillea, two main centers of diversity occur in S.E. Europe and S.W. Asia. Diversified essential oil compositions from Balkan Peninsula have been numerously reported. However, report on essential oils of Achillea species growing in Turkey, which is one of the main centers of diversity, is very limited. This paper represents the chemical compositions of the es...

Cyperus longus is one of the Iranian endemic species. However, to date, and to the best of our knowledge, there are no availale academic reports on the cytotoxicity of this plant. Thus, this study was carried out to examine the in vitro anti-proliferative and anti-apoptotic effects of Cyperus longus extract, fractions and essential oil (EO) on MCF7 and PC3 cell lines. The chemical constituents ...

Common sage (Salvia officinalis L.; Lamiaceae) is one of the most important herb known for its essential oil richness and extensive use in folk medicine. In the current study, we determined the effects of three drying methods on the chemical composition of the essential oil of Saliva officinalis L. The aerial parts of Saliva officinalis were collected from Iran at the full-flowering stage and d...
