The chemical composition of the essential oils of Melaleuca armillaris Sm., Melaleuca styphelioides Sm. and Melaleuca acuminata F. Muell., collected in Tunisia, was studied by means of GC and GC-MS analysis. In all, 46 compounds were identified, 38 for M. armillaris, 20 for M. acuminata and eight for M. styphelioides, respectively. The presence of a sesquiterpenic fraction (52.2%) characterized...

we studied the antioxidant activities of the essential oils of zataria multiflora boiss. (zeo) and bunium persicum (boiss.) b. fedtsch (beo) in mixed form on linseed oil using (dpph•), ­(­abts•+), h2o2 scavenging, and reducing power assays. after calculation of ic50 for zeo and beo separately, interactions of the essential oils were investigated at the form of mixture and the results were given...

The chemical composition of the essential oil constituent from Seinat (Cucumis melo var. tibish) seeds was analyzed by gas chromatography-mass spectrometry (GC-MS). Forty components were identified; with 9, 12-Octadecadienoic acid, methyl ester (15.27%), 2H-Pyran-2one, tetrahydro-6-nonyl (14.60%) being the main constituents in the essential oil. Based on their functional groups, the ester compo...

The compound of essential oil of thyme which was morphologically similar to Thymus pubescens (Lamiaceae) grown at Azarbijan region, was different from pervious reporters. This secondary metabolite extracted from this plant is citronellol which is the main essential oil in the rosa family. These findings showed clear chemical polymorphism with the Th. pubescens taxon that might lead us to new sp...

abstract       background and objective: the aim of this study was to determine the chemical composition, antibacterial and antifungal effects of thymus vulgaris and cuminum cyminum essential oils against foodborne pathogens and candida species in vitro.       methods: the essential oils were extracted from the aerial parts of thymus vulgaris and dried cuminum cyminum seeds using a clevenger ap...

Inula species are medicinal and aromatic plants used for folk medicine extensively. In this work, hydrodistilled essential oil of Inula graveolens (Linnaeus) Desf. analyzed by GC-MS which revealed that bornyl acetate was the major product (69.15%). Camphene was the second major compound (11.11%). Antiproliferative activity of the essential oil and bornyl acetate was investigated on HeLa (human ...

Purpose: Suitable ratio of essential fatty acids has an important role in maintaining good health. There is no pure oil with an ideal fatty acid composition and oxidative stability. The main goal of the present study was to evaluate the physical, chemical and nutritional properties of oil obtained by blending flaxseed oil as a rich source of ω3 fatty acids with sesame and olive oils. Methods: T...

Alicyclobacillus acidoterrestris is considered to be one of the important target microorganisms in the quality control of acidic canned foods. There is an urgent need to develop a suitable method for inhibiting or controlling the germination and outgrowth of A.acidoterrestris in acidic drinks. The aim of this work was to evaluate the chemicals used in the lemon industry (sodium benzoate, potass...

BACKGROUND Insecticide application is the main way to control Diaphorina citri. However, it causes environmental contamination, has a negative impact on beneficial organisms and leads to psyllid resistance. The essential oil of Piper aduncum has low toxicity towards the environment and contains dillapiol, which has proven to be effective against several crop pests. Here, we studied its efficacy...
