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 ...

background : essential oils are the volatile fraction of aromatic and medicinal plants created after extraction by steam or water distillation. species of the genus citrus (rutaceae) have been widely used in traditional medicine as volatile oils and are currently the subject of numerous research. citrus essential oil consists of different terpens that have antitumor activities. this study deter...

the genus ixiolirion, belonging to the amaryllidaceae family, contains about 3 species distributed in center and southwest of asia and northeast of africa. the iranian flora consists of only one bulbous flowering species; ixiolirion tataricum (pall.) herb., with the persian name of “khiarak”. in the present work, i. tataricum was collected, during the flowering stage, from the sarduiyeh area in...

Aflatoxins are highly toxic and carcinogenic metabolites produced by Aspergillus parasiticus on food and agricultural commodities. Natural products may control the production of aflatoxins. The aims of this study were to evaluate the Inhibition of Aspergillus flavus (La3228) and A. parasiticus (Ab2242) growth and their aflatoxin production exposed to the essential oil extracted from fresh leave...

essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. lythrum salicaria has not been previously subjected to examination of its volatile oil. the present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using conventionally hydro-distillation (hd) and microwave a...

in order to compare planting season effect on agronomic of characters and yield of dill (anethum graveolens l.) an experiment based on completely randomized design with three replications was conducted in 2006-07 in esfahan province and three planting seasons (spring, summer and autumn) were evaluated. essential oil compositions were obtained by clevenger and recognized by gc-mass and gc. accor...

the water-distilled essential oil from dried aerial parts of achillea tenuifolia lam. was analysed by gc and cg/ms. 48 components were characterized representing 88% of the total oil. camphor (18%), 1,8-cineole + limonene (9%) and spathulenol (7%) were the major constituents of the oil obtained in a yield of 0.23%.

todays, essential oils from aromatic plants have been qualified as natural antioxidants and proposed as potential substitutes of synthetic antioxidants in food products. in this research chemical compositions and antioxidant activity of artimisia essential oil on oxidative stability of frying oil were analyzed. essential oil was extracted by hydro distillation and its chemical composition was d...

The in vitro antibacterial and antioxidant activity of the essential oil and its two main components of Grammosciadium scabridum Boiss. (Apiaceae) growing wild in Iran, as well as the composition of its essential oil were studied. A total of 19 compounds representing 99.9% of the oil has been identified. Gamma-Terpinene (73.5%), p-cymene (14.2%) and (E)-beta-farnesene (5.3%) were characterized ...
