The residues obtained after hydrodistillation of three aromatic plants (Calamintha grandiflora, Myrrhis odorata and Tussilago farfara) were separated into solid and liquid fractions. The liquid fraction was dried while the solid fraction was extracted with acetone, methanol or ethanol. Two main types of antioxidant activity tests were employed: i) assays to evaluate oxidation of fats, oils and ...

Pressurized hot water extraction (PHWE) and hydrodistillation were compared for the extraction of essential oil from Lavandin. Using GC-FID analysis in conjunction with central composite design, the maximum extraction yield was obtained for temperature of 148 o C, pressure of 33.7 (bar), static time of 10.7 (min), dynamic time of 17.6 (min), and flow rate of 0.69 (mL/min). The PHWE is a practic...

The volatile organic compounds (VOCs) of two Coronilla species (Coronilla orientalis Miller and Coronilla varia L.) obtained by hydrodistillation (HD) and solid phase microextraction (SPME) techniques were identified by GC-FID/MS. The major compounds identified in the SPME extracts were limonene (43.4%) in C. orientalis, (Z)-β-ocimene and (E...

Huntington's disease (HD) is a congenital, progressive, neurodegenerative disorder characterized by cognitive, motor, and psychological disorders. Clinical diagnosis of HD relies on the manifestation of movement abnormalities. In this study, we introduce a mathematical method for HD detection using step spacing. We used 16 walking signals as control and 20 walking signals as HD. We took a s...
