The general need to slow the depletion of fossil resources and reduce carbon footprints has led to tremendous effort being invested in creating "greener" industrial processes and developing alternative means to produce fuels and synthesize platform chemicals. This work aims to design a microwave-assisted cascade process for a full biomass valorisation cycle. GVL (γ-valerolactone), a renewable g...

A combinatorial extraction method and an automated matrix-assisted laser desorption/ionization (MALDI) mass spectrometry procedure were used to improve the clinical analysis of the immunosuppressant drug cyclosporin A. Cyclosporin extracts from whole blood were analyzed by MALDI and electrospray ionization (ESI) mass spectrometry, allowing for their identification and quantification. Due to lim...

Since solid-phase and liquid-phase microextraction (SPME and LPME) were introduced, as effective solvent-free methods, many efforts have been made to improve their modes and applications. However, due to limitations with sensitivity and efficiency, researchers have focused on improving the performance of their basic primary modes. In this way, in recent years, different methods such as ultrason...

Colletotrichum musae is an important cosmopolitan pathogenic fungus that causes anthracnose in banana fruit. The entire genome of C. musae isolate GM20 (CMM 4420), originally isolated from infected banana fruit from Alagoas State, Brazil, was sequenced and annotated. The pathogen genomic DNA was sequenced on HiSeq Illumina platform. The C. musae GM20 genome has 50,635,197 bp with G + C content ...

A variety of extraction procedures were evaluated for the extraction of arsenic and other analytes from lobster tissue samples using inductively coupled plasma mass spectrometry (ICP-MS) detection. Soxhlet, room temperature mixing, sonication, microwave assisted, supercritical carbon dioxide and subcritical water extractions were evaluated for a variety of solvent systems and optimum conditions...

A method of microwave-assisted extraction coupled with high-speed counter-current chromatography was established for separation and purification of isopimpinellin, pimpinellin and phellopterin from Toddalia asiatica (L.) Lam. The conditions of MAE including the extraction solvent, size of sample, solid/liquid ratio, extraction temperature and extraction time were optimized by a mono-factor test...

In this study, the bioactive compounds of loquat fruit (Eriobotrya japonica Lindl.) skin and pulp extracted by two extraction methods (solvent and ultrasound-assisted) with three solvents (ethanol, water and ethanol-water) were compared to supercritical fluid extraction. The antioxidant activities of skin and pulp extracts were evaluated and compared to tertiary butylhydroquinone (TBHQ) using 2...

in this work, an environmentally friendly sample pre-treatment method, ultrasound assisted surfactant enhanced emulsification microextraction (uaseme) followed with spectrofluorimetry was performed for determination of oxadiazon residues in water samples. after the determination of the most suitable extraction solvent and its volume, other parameters such as type and concentration of surfactant...

Berry fruit by-products are a source of polyphenol compounds and highly nutritious oils can be reused to fulfill the requirements circular economy model. One methods obtaining polyphenol-rich extracts or is extraction. Applying conventional solvent extraction techniques may insufficient reach high lipid fraction yields selectivity specific compounds. Alternative methods, mainly ultrasound-assis...
