The aim of this study was to determine the effects of the essential oil of Thymus serpyllum L. and of its components thymol and total phenols (total phenolic content, TPC) extracted from the plant on the growth and mycotoxin production of Aspergillus ochraceus, A. carbonarius, and A. niger. Minimal inhibitory concentration (MIC) determined for the essential oil and thymol, and selected concentr...

background: the hazardous nature of aflatoxins to human and animals necessitate the establishment of control measures. objectives: the effect of two medicinal plants, satureja khozistanica and satureja macrosiphon, was studied on inhibiting aspergillus flavus growth and reducing aflatoxin b1-content in the liquid medium. methods: essential oils were isolated by hydrodistillation method, using a...

Essential oils on the market were analyzed using GC-MS and the main ingredients of each essential oil were quantified. Analysis of the essential oil of Lavandula officinalis (lavender oil) showed that each sample had a different ratio of the contents of main ingredients, such as linalool, linalyl acetate, and camphor. In addition, some commercial lavender oils were analyzed by GC-MS for compari...

The essential oil yield stability of damask rose (Rosa damascena Mill.) as an important medicinal and aromatic plant in different environments has not been well documented. In order to determine appropriate stability parameters, six statistics were studied for essential oil stability of 35 Rosa damascena landraces in seven locations (Sanandaj, Arak, Kashan, Dezful, Stahban, Ke...

Two species belonging to the genus Salvia (Salvia brachyodon Vandas and Salvia officinalis L.) from Dalmatian region were studied for their essential oil composition, genome size and base composition. These species showed the same chromosome number (2n 1⁄4 14), similar genome size (0.95 and 0.97 pg/2C) and base composition (38.52 and 38.55 GC%), respectively. This is the first estimation of DNA...

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...

Anethum graveolens Linn. (Umbelliferae, A. graveolens) is a widely used spice with a long history of traditional medicinal use for the treatment of various ailments. The biosynthesis of secondary metabolites in medicinal and aromatic plants is affected by abiotic stresses such as water deficit. This study was carried out to evaluate seed yield and essential oil of dill under five irrigation dis...

The aim of this study was to analyze the chemical composition of the essential oil from leaves of Lippia gracilis genotypes, in the dry and rainy seasons, and with and without irrigation. The extraction of essential oil was realized by hydrodistillation in a Clevenger apparatus. The chemical composition analysis was performed using a GC-MS/FID. The leaves of the L. gracilis genotypes provide es...

introduction: oxidative degradation of lipids is a major factor limiting the shelf life of foods. the free radical reaction of lipid peroxidation is generally responsible for the deterioration of fatty foods. in general, use of synthetic antioxidants during the manufacturing process are applied to prevent fat oxidative and rancidity while their carcinogenic effects have been approved. since the...
