Development of a method for analysis of Iranian damask

Aug 08, 2008 · Gas chromatography-mass spectrometry (GC-MS) combined with Chemometric resolution techniques were proposed as a method for the analysis of volatile components of Iranian damask rose oil. The essential oil of damask rose was extracted using hydrodistillation method and analyzed with GC-MS in optimized conditions. Effect of shade level and mulch type on growth, yield and Apr 04, 2019 · Essential oil yield ranged from 0.051 to 0.055% in different treatments . Damask rose essential oil yield was not significantly affected by different shade level and mulch types. The analysis of essential oil of R. damascena led to the identification of twenty six compounds. The total area percentages of damask rose components were 88.8 to 95.3%.

Plants and plant products are continuously being explored in medicine against the increasing number of antibiotic resistant organisms. The antimicrobial activity of essential oil of some plants has been demonstrated against a range of organism. This study aimed to determine the chemical constituents and the antimicrobial effects of the oil of grape peels on some clinical isolates. Frontiers Essential Oils:Sources of Antimicrobials and Jan 16, 2017 · Aromatic and medicinal plants produce essential oils in the form of secondary metabolites. These essential oils can be used in diverse applications in food, perfume, and cosmetic industries. The use of essential oils as antimicrobials and food preservative agents is of concern because of several reported side effects of synthetic oils. Essential oils have the potential to be used

Genetic characterization of Rosa damascena species growing

Seven Rosa damascena samples and two check samples were collected and studied for both of the chemical oil and the molecular genetics composition. Results of oil chemical analyses of the different samples showed a great deal of resemblance among essential oils resultant from rose samples collected from the same region. The molecular genetics analyses for the same samples using both Influence of Nitrogen Fertilizers on the Yield and The influence of nitrogen fertilizers on the yield of crop, as well as on the production and composition of the essential oil and some other chemical characteristics of thyme, was investigated. Different levels of fertilizers (N = 0, 45, 90, and 135 kg ha-1) were applied. It was found that fertilizers increase thyme crop, but differences in the yield of essential oil were not remarkable
