Twenty three different wild blackberry fruit samples were assessed regarding their phenolic profiles and contents (by LC/MS quadrupole time-of-flight (QTOF) and antioxidant activity (ferric reducing ability of plasma (FRAP) and 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS)) by two different extraction methods. Thirty four phenolic compounds were detected (8 anthocyanins, 15 flav...

Various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction and supercritical fluid extraction have been developed for the extraction of medicinal plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts. This review was conducted to introduce and compare the conventi...

The O-rings are the very commonly employed solution for creating sealing to prevent loss of pressurized fluid or gases. In present work design an O-ring with no-groove arrangement is presented.

Supercritical fluid chromatography (SFC), combined with mass spectrometry (MS), was employed for the determination of five chiral fungicides, from two different chemical families (acylalanine and triazol) in wine vineyard soils. The effect SFC parameters (stationary phase, selector, mobile phase modifier additive) resolution between enantiomers efficiency compounds ionization at electrospray so...

Vine-shoots are an important waste in all viticulture areas that should be re-used with innovative applications. The aim of this work was to produce Airén waste vine-shoot aqueous extracts by four solid-liquid extraction techniques such as conventional solid-liquid extraction (CSLE), solid-liquid dynamic extraction (SLDE-Naviglio), microwave extraction (ME), and pressurized solvent extraction (...

The O-rings are the very commonly employed solution for creating sealing to prevent loss of pressurized fluid or gases. In present work design an O-ring with inner sided restrained arrangement is presented.

BACKGROUND Thymol (2-isopropyl-5-methylphenol) is the main monoterpene phenol found in thyme essential oil. This compound has revealed several biological properties, including antibacterial, anti-inflammatory and antioxidant activities. In this work, a comparison was made between the performance of different green solvents (ethanol, limonene and ethyl lactate), by pressurized liquid extraction ...

In urban areas wastewater treatment plant (WWTP) effluent can represent a significant component of freshwater ecosystems, and WWTP effluent can be a point source for a variety of pollutants, including pharmaceuticals and personal care products (PPCPs). We analyzed two field sites in the Chicago region: (1) an urban river receiving effluent from a large WWTP; and (2) a suburban river receiving e...
