Increasing importance of pharmaceutical plants in the world and the presence of many of these plants in our country, which has one of the richest Flora of the world, suggest the need for comprehensive studies. Research of secondary metabolites of medicinal and essential oily plants from Iran’s dry to super dry deserts is very important. One of the most famous species from “Labiatae” family is D...

The essential oils of two plants of the genus Bunium called the common name "Zireh" in Persian have been analyzed using GC, GC/MS and 13C NMR spectroscopy. The oils were subjected to antibacterial activity tests. The essential oils have been extracted using hydro-distillation method. The Oils were subjected to analytical GC and GC/MS. The components of the oils were identified using GC retentio...

The object of this research was to find an alternative to fungicide for the prevention of postharvestfruits. Therefore the effect of Zataria multiflora essential oil on the quality of Sultana grapes followingthe harvest was investigated. The essential oil was extracted by hydro-distillation and analyzed using acombination of GC and GC/MS. The results indicated a high percentage of anti-fungal c...

objective(s):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...

in this study, aerial parts of lippia citriodora kunth were harvested at three phenological stages (i.e. vegetative, full flowering and fruit set). the essential oil isolated by hydro distillation for 3 h using a clevenger-type apparatus and the oil was analyzed by gc and gc-ms. the yields of oils (w/w%) in different stages was in the order of: full flowering (0.9%), vegetative (0.48%) and frui...

Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...
