A gas chromatography mass spectrometry (GC-MS) method has been developed and fully validated for the simultaneous determination of natural borneol (NB) and its metabolite, camphor, in rat plasma. Following a single liquid-liquid extraction, the analytes were separated using an HP-5MS capillary column (0.25 mm×30 m×0.25 μm) and analyzed by MS in the selected ion monitoring mode. Selected ion mon...

The temperature-dependent terahertz spectra of the partially-disordered and ordered phases of camphor (C10H16O) are measured using terahertz time-domain spectroscopy. In its partially-disordered phases, a low-intensity, extremely broad resonance is found and is characterized using both a phenomenological approach and an approach based on ab initio solid-state DFT simulations. These two descript...

In this study, a theoretical approach was used to study the UV absorption of the UVB filter, 4-methylbenzylidene camphor. The main objective of this work was to design new UVA filters based on this rather photo-stable compound, so that photo-degradation in this UV region can be avoided without the use of other molecules. This objective was achieved by the simultaneous addition of two appropriat...

The motion of a self-propelled particle is affected by its surroundings, such as boundaries or external fields. In this paper, we investigated the bifurcation of the motion of a camphor grain, as a simple actual self-propelled system, confined in a one-dimensional finite region. A camphor grain exhibits oscillatory motion or remains at rest around the center position in a one-dimensional finite...

conclusions according to antioxidant activity outcomes, the amount of ic50s of aqueous extracts of flower and stem and also butylated hydroxyl toluene (bht) as standard were 232.34, 63.25 and 45.59 ppm respectively. ultimately, it was highlighted that antioxidant activity of aqueous extract of flower was weaker than stem. results sixty one compounds were identified in the essential oil of the f...

the composition of the volatile oils obtained from the aerial parts of artemisia deserti krasch. and a. oliveriana j. gayex dc. was analyzed by gc and gc/ms. while the oil of a. deserti contained camphor (45.5%), 1,8-cineole (16.7%), piperitone (8.6%), ?-pinene (5.7%) and isoborneol (3.2%), the oil of a. oliveriana contained ?-thujone (65.4%), camphor (11.5%), 1,8-cineole (9.2%) and pinocavone ...
