Blueberries are rich in polyphenols, vitamins, and minerals, enhancing their health benefits. Extracting bioactive compounds from blueberries is vital for the pharmaceutical, nutraceutical, food industries. Ultrasound-assisted extraction (UAE) an efficient eco-friendly method isolating phenolic compounds. This study employed response surface methodology (RSM) to optimize UAE conditions, specifically focusing on solvent composition, volume, time, maximize total polyphenol (TP) anthocyanin (TA) content. Blueberry samples were extracted using acidified methanol as primary ultrasonic bath. Optimal conditions determined a quadratic Box–Behnken design analyzed through ANOVA. Results showed that composition had most significant effect TP TA extraction, followed by while time least influence. The optimized be solution 99:1 v/v (12.5 mL) of 97.7 min TP, TA, optimal 17.9 mL same with 100.9 min. Obtained these 408.2 ± 3.9 mg GAE/100 g FW 127.4 1.7 C3GE/100 TA. These findings highlight effectiveness combined RSM blueberries, providing framework industrial-scale applications process.

Developments and Applications of Molecularly Imprinted Polymer-Based In-Tube Solid Phase Microextraction Technique for Efficient Sample Preparation

Molecules, Год журнала: 2024, Номер 29(18), С. 4472 - 4472

Опубликована: Сен. 20, 2024

Despite advancements in the sensitivity and performance of analytical instruments, sample preparation remains a bottleneck process. Currently, solid-phase extraction is more widely used than traditional organic solvent due to its ease use lower requirements. Moreover, various microextraction techniques such as micro extraction, dispersive microextraction, stir bar sorptive liquid-phase magnetic bead have been developed minimize size, reduce usage, enable automation. Among these, in-tube (IT-SPME) using capillaries devices has gained attention an advanced “green technique” that combines miniaturization, on-line automation, reduced consumption. Capillary tubes IT-SPME are categorized into configurations: inner-wall-coated, particle-packed, fiber-packed, rod monolith, operating either draw/eject system or flow-through system. Additionally, developments novel adsorbents monoliths, ionic liquids, restricted-access materials, molecularly imprinted polymers (MIPs), graphene, carbon nanotubes, inorganic nanoparticles, organometallic frameworks improved efficiency selectivity. MIPs, particular, stable, custom-made with molecular recognition capabilities formed during synthesis, making them exceptional “smart adsorbents” for selective preparation. The MIP fabrication process involves three main stages: pre-arrangement capability, polymerization, template removal. After forming template-monomer complex, polymerization creates polymer network where molecules anchored, final step removing produce cavities complementary molecules. This review first paper focus on MIP-based IT-SPME, which integrates selectivity MIPs efficient summarizes recent applications.
