Background: The genus Thymus is a perennial and aromatic plant and belongs to Lamiaceae family. The essential oils of these plants are used for the treatment of mouth and throat mucosal inflammation, catarrh and respiratory disorders and as antioxidant and antiseptic. Objective: The purpose of this study was to compare chemical composition of the essential oils derived from aromatic waters of ...

With the aim of investigating the effects of carbonaceous sorbent amendment on plant health and end point contaminant bioavailability, plant experiments were set up to grow maize (Zea mays) in soil contaminated with polycyclic aromatic hydrocarbons (PAHs) and metals. Maize and pine derived biochars, as well as a commercial grade activated carbon, were used as amendments. Plant growth characteri...

The aromatic compounds cinnamic and p-hydroxycinnamic acids (pHCAs) are phenylpropanoids having applications as precursors for the synthesis of thermoplastics, flavoring, cosmetic, and health products. These two aromatic acids can be obtained by chemical synthesis or extraction from plant tissues. However, both manufacturing processes have shortcomings, such as the generation of toxic subproduc...

Aloe vera (Asphodeloideae) is a medicinal plant in which useful secondary metabolites are plentiful. Among the representative secondary metabolites of Aloe vera are the anthraquinones including aloe emodin and chrysophanol, which are tricyclic aromatic quinones synthesized via a plant-specific type III polyketide biosynthesis pathway. However, it is not yet clear which cellular responses can in...

Although the use of olfaction by birds is now widely recognised, the olfactory abilities of passerine birds remain poorly explored, for historical reasons. Several studies however suggest that passerines can perceive volatile compounds in several biologically relevant contexts. In Corsica, recent findings suggest that cavity-nesting blue tits may use volatile compounds in the context of nest bu...

This study was conducted on experimental field at Garmsar zone in Iran during 2010 – 2011 in order to Evaluation of medicinal plant valerian (Valeriana officinalis L.) essential oil compositions cultivated at Garmsar zone in Iran. Sowing date was 20 September and planting densitiy was 80000 plant ha. The volatile constituents of the root part of cultivated Valeriana officinalis were isolated by...

Metabolism of simple aromatic compounds in rhizobial strains has been a subject of study for a few decades, due either to the significance of nutritional diversity in the inoculum survival during agricultural applications or to the importance of plant phenolics in the microbe-plant cross-talk and signal-transduction. Here, we report the capability of rhizobial strains to catabolize polychlorina...

Chorismate mutase (EC 5.4.99.5) catalyzes the first step in the branch of the shikimate pathway which leads to the aromatic amino acids, phenylalanine and tyrosine. We have isolated a cDNA for this enzyme from the higher plant, Arabidopsis thaliana, by complementing a yeast strain (aro7) with a cDNA library from A. thaliana. This is the first chorismate mutase cDNA isolated from a plant. It enc...

Comprehensive extraction coupled to NMR metabolomics was applied to the identification of active compounds from Morus alba stem bark binding to the adenosine A1 receptor. Orthogonal projection to the least square (OPLS) analysis was used to estimate which compounds significantly correlate with the activity. Based on the loading bi-plot and Y-related coefficient plot, unsaturated fatty acid sign...
