Abstract: The chemical composition of essential oil isolated by hydro distillation from the aerial parts of Thymus daenensis subsp. daenensis Celak., at different harvest times were determined using Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GC-MS). Twenty six components were identified in Thymus daenensis essential oils. The main components of the oil were thymol (66.62-71.49 %), p-cymene (5.52-7.12 %), β-caryophyllene (3.91-4.09 %), δ-terpinene (3.22-4.3 %) and carvacrol (2.64-2.77 %). The total phenolic content and the antioxidant activity of plant extract was determined by Folin-Ciocalteau and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assays and ferric reducing antioxidant power (FRAP) assay respectively. Total phenols varied from 18.82 to 18.97 (mg GAE/g dw) and the IC in the radical scavenging assay ranged from 8.23 to 8.46 mg/ml and FRAP values ranged form 24.23 to 26.45 µM Quercetin E/g dw. The highest thymol content and radical scavenging effect was found in fl...

TL;DR: Two main conclusions have been reached: first, that the present state of medical education in Cambridge is beyond any doubt unsatisfactory; and, secondly, that to preserve the status of Cambridge as a medical school something must be done.
Comprehensive two-dimensional liquid chromatography in analysis of Lamiaceae herbs: Characterisation and quantification of antioxidant phenolic acids
TL;DR: A fast and effective dynamic sonication assisted ethanol extraction method was developed for extracting phenolic acids from basil, oregano, rosemary, sage, spearmint and thyme of the Lamiaceae family and the results were compared with results obtained by conventional solvent extraction techniques.
