achillea millefolium belong to the asteraceae family and from genus achillea. in this study essential oils were extracted from all aerial parts via hydro distillation (hd) method by clevenger set . by using of gas chromatography/mass spectrometry ( gc-ms) technique the chemicals component essential oil were identified. about 41 components with were identified which encompassed 97.66 percent of ...
the essential oil of prangos ferulacea (apiaceae) fruits was obtained by hydrodistillation and analyzed by gas chromatography (gc) and gc-mass spectrometery (ms). among the 39 identified constituents accounting for 99.99% of the total oil, the major components were chrysanthenyl acetate (26.53%), limonene (19.59%), alpha pinene (19.50%), delta-3-carene (6.56%), mesitaldehyde (6.09), and germacr...
the essential oil of peucedanum ru t h e n i c u m fruits, obtained by hydrodistillation, was analyzed by gas chromatography and gas chromatography mass spectrometry. among the 31 identified constituents accounting for 83.9% of the total oil, the major components were 1,8-cineole (11.15%), camphor (5.86%), z-carveol (6.88%), l-carvone (5.61%), 8,9-dehydroisolongifolene (11.35%), caryophyllene o...
The experiment was aimed to study the chemical constituents of essential oils from two Pimpinella L. species including P. deverroides - Boiss, and P. tragium Vill. growing wild in Iran. To do this, the essential oil of fruits of two P. tragium populations (Sefidkhani and Hesar, Markazi province, Iran) and one population of P. deverroides (Kerend, Kermanshah province) were extracted by a Cleveng...
The chemical composition of the essential oil obtained from aerial parts of Galium verum L. (Rubiaceae) from Iran was examined by a combination of GC and GC/MS. The oil isolated by hydro-distillation using a Clevenger-type apparatus. Air-dried aerial parts of Galium verum (80 g) which were collected from Bomehen in Tehran province at full flowering stage on May 2003, were subjected to hydro-dis...
Aerial parts of the plant (250 g) were collected during flowering in April 2000 from Tehran province in Iran. The essential oil was obtained by steam distillation of air-dried aerial parts in an all-glass apparatus. The sample oil that was light yellow in color was dried over anhydrous sodium sulfate and stored under nitrogen in a sealed vial until required. The essential oil was examined by GC...
In this work the chemical composition and antimicrobial activity of Pelargonium roseum leaves essential oil that grown in southwest of Iran were determined. The hydrodistilled volatile components were identified by GC/MS analysis. A total of 33 components have been identified in the oil, representing 99.38% of the total oil and citronellol (44.63%), citronellyl formate (14.22%), isomenthon (6.3...
several attempts have so far been made in the search of new anticancer agents of plant origin. some studies have reported that different species of pine genus possess cytotoxic activities against various cancer cell lines. in the present study, we evaluated the cytotoxic effects of pinus eldarica bark and leaf extracts or leaf essential oil on hela and mcf-7 tumor cell lines. hydroalcoholic and...
Superheated water extraction is used to extract essential oil of leaves of Origanum micranthum. The effect of different temperatures on the essential oil profile and rate of extraction as a function of time is investigated. The components of essential oil of Origanum micranthum are removed from the aqueous extract by C18 solid-phase extraction. The identification of components is carried out us...
ABSTRACT Background and objectives: Utilization of essential oils instead of chemical preservatives has received significant attention in recent years. The present study aims to evaluate chemical composition and antibacterial and antioxidant properties of essential oils of Zataria multiflora, Artemisia deracunculus and Mentha piperita. Methods: Chemical profile of th...
