Ultrasound coupling subcritical water extraction (USWE) was developed to extract polyphenols from Phyllanthus emblica pomace (PPEPs), and extraction parameters affecting the yield of PPEPs were systematically optimized. USWE was comprehensively evaluated in terms of extraction parameters, yield, antioxidant capacity, major bioactive components, and infrared characteristics of PPEPs, and compared with four other extraction methods. Microstructural changes in the pomace were examined using scanning electron microscopy (SEM) to elucidate the interactions between the extraction process and the plant matrix. Finally, to address the issues of the instability of PPEPs and their low bioavailability, liposomal encapsulation was performed and the physicochemical properties were evaluated. Results demonstrated that the yield of PPEPs from USWE was 1.8-fold and 1.35-fold higher than those from solvent extraction (SE) and subcritical water extraction (SWE), respectively. Furthermore, PPEPs from USWE exhibited the strongest antioxidant activity and higher levels of six major bioactive compounds. SEM analysis revealed a significant increase in porosity and enlarged pores in USWE-treated pomace. Additionally, Phyllanthus emblica polyphenol liposomes (PPEPL) were prepared by thin-film dispersion technique. PPEPL showed a high encapsulation efficiency of 83.07 ± 0.09 % and retained structural integrity after 4 weeks of storage at 4 °C. PPEPL exhibited enhanced antioxidant activity compared to free PPEPs. The IC50 values for scavenging DPPH·, ABTS·+, and hydroxyl radicals were 3.2-, 3.3-, and 1.6-fold lower, respectively. In summary, integrating USWE with liposome technology provides an efficient strategy for obtaining stable, high-quality bioactive PPEPs.

Tetracycline (TC) and Cr(VI) often co-occur in wastewaters, where their synergistic toxicity and contrasting redox behaviors complicate remediation. In this study, ultrasonic cavitation was employed as a employed as a green and efficient process to simultaneously degrade TC and reduce Cr(VI). Under optimal conditions (20 kHz, 12 mm probe, 131 μm amplitude, 308 K), TC and Cr(VI) removal reached 62.9 % and 70.8 % within 2 h, respectively. The synergistic mechanism was elucidated through radical quenching, electron paramagnetic resonance (EPR) spectroscopy, and complementary computational fluid dynamics (CFD) simulations and density functional theory (DFT) calculations. Cavitation bubble collapse generated both oxidative and reductive radicals, enabling concurrent oxidation and reduction. Radical identification showed that ·O2- and ·H were the dominant reductants responsible for Cr(VI) reduction, whereas 1O2 and ·OH primarily controlled TC degradation. CFD simulations further demonstrated that mechanical energy, internal energy, and bubble growth rate during cavitation were positively correlated with radical generation. Importantly, experimental evidence suggested that Cr(VI) promoted the conversion of ·O2- into 1O2, establishing a coupled radical pathway that linked metal detoxification with antibiotic degradation. Furthermore, Cr(V) intermediates were detected as key transient species, exhibiting strong oxidative capacity toward TC and accelerating Cr(VI) reduction. Complementary DFT calculations confirmed that the coexistence of TC and ·H markedly lowered the energy barrier of Cr(VI) reduction. Overall, this work provides new mechanistic insight into radical transformation and metal-organic coupling under ultrasonic cavitation, and highlights its potential as a sustainable strategy for treating waters co-contaminated with metals and antibiotics.
