Finding an environment-friendly and affordable method to remove contaminated soils from Polycyclic Aromatic Hydrocarbons (PAHs) has now become an attractive field for researchers, with super-critical fluid extraction being an innovative process in the field of contaminated soil treatment. Extraction with super-critical fluid is a simple and rapid extraction process that uses super-critical flui...

In order to respond to the basic requirements of food and pharmaceutical industries, to reduce or eliminate organic solvent residues in the final products, several extraction techniques were tested from the standpoint of performance, with low energy consumption. The aim of this study was to determine biological activities such as antioxidant and antiproliferative activities of flavonolignans fr...

In this study phenolic compounds extraction from grape byproducts was conducted using pure water as a solvent. High temperatures and low time incubation periods were used in the aim of reducing the cost of the process and heightening the phenolic compounds yield. Response surface methodology (RSM) was realized to study the effect of time and temperature on crushed and uncrushed grape pomace. Th...

In the preceding paper of this series (l), our studies on stimulat.ion of the synthesis of transfer ribonucleic acid in liver and seminal vesicle by the appropriate steroid hormones were described. The 32P-RNA formed during a brief exposure to isotope and isolated by phenol extraction at low temperatures was found to consist of labeled transfer RNA and a poorly defined RNA that was tentatively ...

In order to maximize the yield of the total phenolic content (TPC) and total monomeric anthocyanin (TMA) from Brosimum alicastrum leaf and to study the radical-scavenging activity, a three-level three-factor Box-Behnken design (BBD) was used to determine the optimal points for ultrasound-assisted extraction (UAE). In this study, we analyzed the extraction time (10, 20, and 30 min), temperature ...

The present article includes the Ultrasound-Assisted Extraction (UAE) of Citrus unsiu Marc. leaves rich in polyphenols. The best possible combinations of solvent, pH of the media, solvent/solid ratio, extraction time, extraction temperature and particle size were obtained for the maximum extraction of Total Phenolic Compounds (TPC) and Total Flavonoid Compounds (TFC) by us...

introduction: the purpose of this study was to evaluate the antimicrobial photodynamic therapy (apdt) and low level laser therapy (lllt) on wound healing, pain intensity, swelling problems, halitosis and the postoperative usage of analgesics after surgical removal of lower third molars. methods: one hundred and fifty patients, randomly divided into three groups were selected (50 per each group)...

A simple and solvent-minimized sample preparation technique based on hollow fibre-protected liquid-phase micro-extraction has been developed for extraction of fifteen organic sulphur compounds from aqueous samples. The analysis of the extracted them was performed by gas chromatography equipped with mass spectrometry and/or flame photometric detectors. 3.3 µL of organic solvent located in the lu...
