High-throughput subzero-temperature assisted homogenous liquid-liquid extraction for the fast sample preparation of multiple phenolic compounds in propolis

A Simple High-Throughput Field Sample Preparation Method Based on Matrix-Induced Sugaring-Out for the Simultaneous Determination of 5-Hydroxymethylfurfural and Phenolic Compounds in Honey

“…Reversed-phase HPLC separation was modified based on the literature [ 32 ]. Coumarin was used as the internal standard for quantification, which had proved to be suitable for the simultaneous measurement of multiple phenolic compounds in HLLE [ 33 ]. It can be seen from Figure 3 that all ten target analytes and the internal standard are well separated.…”

Sustainable ultrasound-assisted extraction of Polygonatum sibiricum saponins using ionic strength-responsive natural deep eutectic solvents

“…Environment-triggered phase separation is simple, fast, and efficient when recovering active substances. A particular homogeneous phase can be divided into two phases by responding to changes in pH value, temperature, light, or ionic strength [14] . This method can avoid complex operations such as distillation, adsorption–desorption, and column crossing, reduce the consumption of heat and electric energy, and reduce the equilibration time in the distribution process, which conforms to the concept of green extraction.…”

Subzero-temperature homogeneous liquid–liquid extraction for the stereoselective determination of chiral triadimefon and its metabolite in water, fruit juice, vinegar, and fermented liquor by HPLC

“…17 Cryogenic HLLE is a technique utilized to achieve efficient phase separation at subzero temperatures. 18 This method eliminates the need for additional phase separation reagents or centrifugation steps during sample pretreatment. It has the signicant advantages of simplicity, rapidity, no solvent consumption, and low labor cost.…”
