“…S4, Supplemental information), which shows that a single placement of the extraction vessels could result in parallel extraction for six different samples. Pressurized hot water extraction (PHWE), which uses a condensed phase of water at a temperature range from 100 °C (boiling point of water) to 374 °C (critical point of water), has been the most important of current sustainable extraction strategies71030313233. Using the developed system, it is a simple task to achieve conditions for PHWE with only a couple of minor modifications, such as upgrading the column oven with more advanced equipment that is capable of reaching temperatures up to the critical point of water and replacing the membranes in the extraction vessels with specialized materials that permit the use of high temperatures.…”

Practicing “green analytical chemistry” is of great importance when profiling the chemical composition of complex matrices. Herein, a novel hybrid analytical platform was developed for direct chemical analysis of complex matrices by online hyphenating pressurized warm water extraction followed by turbulent flow chromatography coupled with high performance liquid chromatography-tandem mass spectrometry (PWWE-TFC-LC-MS/MS). Two parallel hollow guard columns acted as extraction vessels connected to a long narrow polyether ether ketone tube, while warm water served as extraction solvent and was delivered at a flow rate of 2.5 mL/min to generate considerable back pressure at either vessel. A column oven heated both the solvent and crude materials. A TFC column, which is advantageous for the comprehensive trapping of small molecular substances from fluids under turbulent flow conditions, was employed to transfer analytes from the PWWE module to LC-MS/MS. Two electronic valves alternated each vessel between extraction and elution phases. As a proof-of-concept, a famous herbal medicine for the treatment of neurodegenerative disorders, namely Polygalae Radix, was selected for the qualitative and quantitative analyses. The results suggest that the hybrid platform is advantageous in terms of decreasing time, material, and solvent consumption and in its automation, versatility, and environmental friendliness.

This review follows up on Part 1, which focused on classification and evaluation of single drop and sorbent‐based microextraction techniques. Membrane‐ and homogenous phase‐based microextraction techniques are discussed and classified in Part 2. These techniques are more recent than those in Part 1 and considerable attention has been paid to their development. The new methodologies are more sensitive and, thanks to their miniaturization, they can be classified as “green”, but no exhaustive classification is available. We hope that this review will contribute to better orientation in these methods.

“…In fact, this technique, known as pressurized hot water extraction (PHWE), allows for (i) increasing the efficiency of water in disrupting analyte-matrix noncovalent interactions (e.g., van der Waals forces, hydrogen bonds, and dipole interactions) and (ii) decreasing its viscosity/surface tension wetting better the sample matrix . Given these features, PHWE has been widely used to extract bioactive compounds, such as antioxidants from vegetal matrices , and micropollutants (e.g., polycyclic aromatic hydrocarbons and alkylphenols) from sediments. , Moreover, PHWE resulted to be effective in the extraction of a heterogeneous group of PhCs from impacted soil and sediments. − …”

A new self-assembled apparatus for the extraction of solid samples was designed and implemented to perform a recirculated pressurized hot water extraction (R-PHWE) directly coupled to liquid chromatography-tandem mass spectrometry. To investigate the potential of this new extraction apparatus, 34 target pharmaceutical compounds were analyzed in loam, silt-loam, and silty-clay-loam soils. The target analytes were characterized by heterogeneous physicochemical properties (e.g., −1.60 ≤ log D ≤ 5.91 at pH = 7.2, i.e., at the mean pH values of the three soils). Design of experiments (DoE) was used to identify the best extraction conditions for the target analytes by studying temperature, pressure, and number of extraction cycles. The results of DoE optimization pointed out the significant influence of the number of cycles on recovery. The application of DoE set point to the three reference soils provided recoveries ≥60% for 21−25 out the 34 target analytes, depending on soil. Good recovery precision (<25%) and moderate suppressive matrix effect (≤40%) were found for most target analytes, regardless of the soil considered. The optimized R-PHWE procedure evidenced statistically higher recoveries for 16 out of 34 target analytes when compared to conventional off-line dynamic PHWE.
