Genus Origanum is an aromatic plant used in folk medicine and as a culinary herb, whose composition of volatile compounds is influenced by the type of species and geographical locations. This research evaluates the effect of altitude on the composition of volatile compounds and the contents of carvacrol and thymol of Origanum x majoricum Cambess and Origanum majorana L. fi...

Supercritical fluid extraction of the volatile oil of the aerial part of the winter savory was carried out in different conditions of pressure, temperature, mean particle size and CO2 flow rate and the results were compared with those obtaining by hydrodistillation with a Clevenger-type apparatus. The non-volatile components were extracted by SFE at higher pressures and by soxhlet extraction wi...

Bulk chondritic meteorites and terrestrial planets show a monotonic depletion in moderately volatile and volatile elements relative to the Sun's photosphere and CI carbonaceous chondrites. Although volatile depletion was the most fundamental chemical process affecting the inner solar nebula, debate continues as to its cause. Carbonaceous chondrites are the most primitive rocks available to us, ...

In this paper, we present a novel method to generate ultra-small droplets via volatile component evaporation. By regulating the composition of the binary solvent, the volume ratio of the high saturated vapor pressure component, and the flow rate ratio of the two phases, monodisperse ultra-small water or nonvolatile organic droplets can be formed. This method is flexible, versatile, and compatib...

Nitrogen (N) is an important macronutrient for plant growth and development, but the regulatory mechanism of volatile compounds in response to N deficiency is not well understood, especially in cucumber, which consumes excessive N during growth. In this study, the major volatile compounds from cucumber leaves subjected to N deficiency were analyzed by GC-MS. A total of 24 volatile components we...

This study investigated the composition of volatile compounds in two pummelo cultivars, including 'Shatian' and 'Guanxi', cultivated in different regions of China with the aim of studying the effect of cultivar and cultivation condition on biosynthesis of volatile compounds in pummelo. Volatile compounds were extracted from pummelo juice using head-space microextraction and then analyzed using ...

Non volatile memories have in recent years become an established component of all electronic systems, especially portable systems. The general trend towards a higher level of integration and speed are pushing towards their integration with complex logic – embedded nonvolatile memory. Non Volatile memory research in the NMRC, which was stimulated by a Marie Curie Fellowship, has focused on the m...

The signals essential to Drosophila melanogaster courtship include pheromones emitted by the female which stimulate the male to court and pheromones emitted by the courting male which stimulate the female to accept. Genetic variation among these phermones is a common (if not universal) requirement for stimulation of either sex. The signal from the courting male to the female involves both a vol...

conclusions antioxidant activity of this essential oil could be somehow attributed to high contents of carvone, carvacrol and thymol. the volatile oil of this plant could have the potential of other biological activities, so further experimental investigations are recommended on this essential oil. results analyses of yellow colored essential oil yielded 88.22% of total oil with 67 components. ...

Ingestion of winter savory extract has been reported to inhibit the decrease in peripheral body temperature in people who experience cold sensitivity. However, the active ingredients underlying this effect are not known. We sought to elucidate the effects of the volatile components of winter savory on body temperature. Carvacrol (the main volatile component and a transient receptor potential ch...
