Sustainable valorization of papaya peels for thrombolytic cysteine protease isolation by ultrasound assisted disruptive liquid phase microextraction with task specific switchable natural deep eutectic solvents

Harish Babu Balaraman et al.

Summary: This study focused on the task-specific purification of thrombolytic cysteine protease from Carica papaya peels using switchable eutectic solvent-based ultrasound-assisted dispersive liquid-phase microextraction. Four switchable polarity natural deep eutectic solvents were synthesized and ultrasound-assisted liquid phase microextraction yielded 33.2 mg/g of papaya protease. The kinetic and thermodynamic modeling of the extraction process indicated that first-order rate laws describe the process, with an optimal time of 15 minutes. The resulting ultrapure protease fraction showed high purity and specific enzyme activity, with thrombolytic activity confirmed through a blood clot digestion assay.

Enhancing enrichment ability of Co-Al- layered double hydroxides-mixed matrix membrane microextraction by deep eutectic solvent for analysis of warfarin in biological samples and its quantification via high-performance liquid chromatography-ultraviolet detection

Zahra Jafari et al.

Summary: Recent studies have investigated the effect of deep eutectic solvents (DESs) on the performance of mixed-matrix membrane (MMM) in microextraction methods. A microextraction method based on a Co-Al-layered double hydroxides mixed matrix membrane (CO-Al-LDH-MMM) and deep eutectic solvents (DESs) was developed for the extraction and quantification of warfarin in biological samples. The method showed good working range and precision, and the recovery studies confirmed its potential for analysis of warfarin in biological samples.
