Deep Eutectic Solvent extraction and biological activity of polysaccharides from Tenebrio molitor

Heliyon, Год журнала: 2025, Номер 11(2), С. e41790 - e41790

Опубликована: Янв. 1, 2025

This study aimed to extract polysaccharides from Tenebrio molitor using ultrasound-assisted deep eutectic solvent (DESs) and evaluate their structural features, as well antimicrobial, antioxidant, α-amylase inhibitory activities. Various DESs were tested for extraction, the process was optimized response surface methodology (RSM). A preliminary analysis of conducted infrared spectrum. The characterized by measuring pH, viscosity, conductivity, refractive index, density. optimal extraction agent parameters determined. Significant differences in conductivity observed among DESs, whereas index density not significant. Choline chloride-lactic acid identified agent. a DES molar ratio 1:2.1, water content 27 %, an temperature 70 °C, time 44 min, resulting yield 18.62 %. extracted exhibited strong effects against Salmonella, along with antioxidant activity demonstrated that can be efficiently showcasing significant biological activities, including antibacterial, properties. These findings highlight potential applications valuable resources.

Pulsed Electric Field (PEF) Treatment Results in Growth Promotion, Main Flavonoids Extraction, and Phytochemical Profile Modulation of Scutellaria baicalensis Georgi Roots

International Journal of Molecular Sciences, Год журнала: 2024, Номер 26(1), С. 100 - 100

Опубликована: Дек. 26, 2024

This study aims to explore the effect of pulsed electric field (PEF) treatment as a method very likely result in reversible electroporation Scutellaria baicalensis Georgi underground organs, resulting increased mass transfer and secondary metabolites leakage. PEF with previously established empirically tailored parameters [E = 0.3 kV/cm (U 3 kV, d 10 cm), t 50 µs, N 33 f 1 Hz] was applied 1–3 times S. roots submerged four different Natural Deep Eutectic Solvents (NADES) media (1—choline chloride/xylose (1:2) + 30% water, 2—choline chloride/glucose 3—choline chloride/ethylene glycol (1:2), 4—tap water (EC 0.7 mS/cm). Confocal microscopy utilized visualize impact on root cells situ. As plant cell membrane permeabilization, an extract containing major active successfully acquired most media, achieving best results using medium repeating twice (baicalein <LOQ, baicalin 12.85 µg/mL, wogonin 2.15 wogonoside 3.01 µg/mL). Wogonin concentration NADES par control (plants harvested day experiment, ultrasound-mediated methanolic extraction, Cwogonin After successful allowed plants continue growing, lowest survival rate across treated groups being 60%. Additionally, enhancement growth (length fresh roots) significant changes phytochemical profile were also observed.
