BACKGROUND Volatile oil from aromatic plants has been used by ancient Egyptians in embalming for the inhibition of bacterial growth and prevention of decay, Callistemon citrinus is used in traditional therapies for the treatment of bronchitis, cough, inflammation and as an antimicrobial herbs. This study examines the essential constituents of the volatile oils obtained from the aerial parts of ...

In recent years, the demand for plant-derived oils as renewable alternatives to fossil oil has increased due to the rising cost of petroleum and the increased concern about the environment. However, the supply of vegetable oils today relies upon only a few crops with low potential for further increases in oil yields. Redirection of carbon flux from starch to oil in the cereal seed can provide f...

Genes involved in fatty acids biosynthesis, modification and oil body formation are expected to be conserved in structure and function in different plant species. However, significant differences in the composition of fatty acids and total oil contents in seeds have been observed in different plant species. Comparative genomics was performed on 261 genes involved in fatty acids biosynthesis, TA...

Plant oil is an essential dietary and bio-energy resource. Despite this, the effects of climate change on plant oil quality remain to be elucidated. The present study is the first to show changes in oil quality and quantity of four rapeseed cultivars in climate scenarios with elevated [CO2], [O3] and temperature (T) combined and as single factors. The combination of environmental factors resemb...

oil contamination is one of the most common and usual kinds of pollution in aquatic and terrestrial ecosystems. one of the economical and effective methods for decreasing or eliminating oil contamination is using plants and microorganisms. soils contain a wide variety of oil decomposing microorganisms, of which pseudomonad, rhodocoous and nocardia are the most important. to evaluate the effect ...

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...

conclusions we concluded that ozonized organic extra-virgin olive oil was a growth inhibitor of giardia cysts, and concerning its compatibility with a biological system, it is recommended for further clinical trials. objectives this study was conducted to evaluate the effect of ozonized organic extra-virgin olive oil on the cyst of g. lamblia. methods the olive oil was ozonized based on interna...

The aim of the present study was to investigate chemical composition and antibacterial activity of essential oil from the leaf of Mentha spicata plant against common food-borne pathogenic bacteria (Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Listeria monocytogenes, Salmonella typhimurium, and Escherichia coli O157:H7). Chemical composition of the essential oil was identified by g...
