“…Prior to adding the extract in product formulation, TBAC has to be separated from the DES4-polygodial mixture due to their unknown effects for human in topical applications, although it was reported that quaternary ammonium salts possess antimicrobial activity against several species of Gram-positive and Gram-negative bacteria. − TBAC was also found to exhibit antiproliferative effects on human colon carcinoma cells of ionic liquids containing the compound . The separation of TBAC from the DES4–polygodial mixture can be done by the addition of antisolvent.…”

Polygodial is a bioactive compound that is present in an ancient native plant known as "horopito" (Pseudowintera colorata) in New Zealand, and it possesses antifungal, antibacterial, antifeedant, insecticidal, and antithelmintic properties. In this work, an approach for polygodial extraction using deep eutectic solvents (DESs) is presented. Two newly prepared DESs based on 1-dodecanol and polyethylene glycol were found to be comparable with ethanol in their polygodial extractability. However, they exposed a superior ability to protect polygodial from degradation and also a better solvent reusability for extraction of polygodial as compared to ethanol. The Box-Behnken design (BBD) in combination with response surface methodology (RSM) was used to design the experiment and optimization of polygodial extraction using the dodecanol-based DES. The optimal condition was acquired at 47.13 °C, for 1.03 h, and 5.01% w/v biomass, where 12.35 ± 0.05 mg of polygodial/g of dried horopito leaf was extracted.

Sulfur dioxide (SO 2 ) emitted from the combustion of fossil flues is a major atmospheric pollutant that seriously threatens the environment and human health. The traditional methods for the removal and recovery of SO 2 are irreversible and can result in secondary pollution or suffer from solvent loss. Therefore, it is urgent to explore new absorbents for the reversible, efficient, and environment-friendly capture of SO 2 . Ionic liquids (ILs) exhibit excellent performance for SO 2 capture because of their unique physicochemical properties. To improve the absorption capacities of ILs for SO 2 , a series of novel etherfunctionalized pyridinium chloride ILs ([E n Py]Cl, n = 2−4) were designed and synthesized. The physiochemical properties of these ILs and their SO 2 absorption performance under different conditions were investigated. In addition, the SO 2 /CO 2 selectivities and reusabilities of the ILs and the absorption mechanism between SO 2 and [E n Py]Cl (n = 2−4) were studied. It was found that 1-[2-(2-methoxyethoxy)ethyl] pyridinium chloride showed a relatively high absorption capacity of up to 1.155 (g of SO 2 )·(g of IL) −1 at 20°C and 0.1 MPa. The SO 2 absorption capacities of the studied ILs remained steady in absorption− desorption cycles, implying that [E n Py]Cl (n = 2−4) could be promising candidates for SO 2 capture.
