Detailed characterization of the synthesized FSI-nZVI revealed aggregated spherical nanoparticles with a size distribution ranging from 30 to 60 nm and multiple functional groups encapsulated on the surface. HPLC-MS analysis indicated that polyphenolic compounds such as rutin in the extract were involved in the green synthesis of FSI-nZVI and were responsible for these functional groups. In the transformation of ginsenoside Rb1 catalyzed by FSI-nZVI, the intermediate 20(S/R)-Rg3 and the final product 20(S/R)−25-OH-Rg3 were obtained via deglycosylation at the C20 position and hydration at the C24(25) double bond of Rb1. The transformation pathways were established as Rb1→20(S/R)-Rg3→20(S/R)−25-OH-Rg3 based on time-course experiments. Under optimized conditions, FSI-nZVI achieved a complete transformation of Rb1 to 25-OH-Rg3 epimers with 100% selectivity within 2 h, demonstrating superior transformation efficiency and selectivity compared to five commercial solid acid catalysts. This study provides a promising method for the green synthesis of efficient catalyst nZVI using biomass, and also facilitates the preparation of 25-OH rare ginsenosides with high efficiency and selectivity.","PeriodicalId":12768,"journal":{"name":"Green Chemistry Letters and Reviews","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

QbD principles were applied to optimize NGS peak shape and resolution using Design Expert software, taking into account flow rate, temperature, and mobile phase. An ACQUITY UPLC HSS C18 Column utilized a mobile phase of 0.1% (v/v) TFA in water and methanol (71:29) at 0.29 mL/min and 27°C, with detection wavelength of 318.0 nm and a retention time of 1.761 min. The method was highly precise, with %RSD of 0.3 and 0.7 and a recovery rate of 100.26%. The LOD and LOQ were 0.34 and 1.04 μg/mL, respectively. A greenness rating was generated using ComplexMoGAPI, AGREE, the ChlorTox Scale, and the Analytical Eco-Scale, with method validation as per ICH Q2, and stability studies identified a degradation product, affirming the method's reliability. The method is simple, cost-effective, and supports quality control, aligning with GAC and QbD principles. It enhances sustainable pharmaceutical analysis by optimizing performance and minimizing environmental impact.

An HPLC study utilizing 0.07 M sodium sulfate adjusted to pH 3.0 and Ethanol (90:10, v/v) with 205 nm UV detection used an isocratic approach. The experiment used a Partisil Hichrom SCX column (150 mm × 4.6 mm, 5 μm), 20 μL injection volume, and a 0.8 mL/min flow rate. The column oven was set at 25°C for each sequence. With the aid of the MCR spectral method, the overlapping of the medications' spectral parameters was efficiently resolved. This technique enabled SDH and BNZ to distinguish at 222.1 and 215 nm wavelengths. HPLC and MCR calibration curves revealed a correlation coefficient exceeding 0.999 for all medications between 10–200 μg/mL and 5–30 μg/mL. The approach produces good recovery results with 98% to 102%.

The traditional solvents used for this purpose are toxic and harmful. Deep eutectic solvents (DESs) as sustainable alternatives to toxic reagents have received considerable attention in current research. In this work, an array of complementary experimental (liquid–liquid equilibrium experiments) and computational (ab initio molecular dynamics, AIMD) techniques were utilized to explore the distinct distribution behaviors, complicated interaction network, and corresponding mechanisms from multidimensional temporal and spatial perspectives. The proposed bromophenylcyanide-based eutectic solvent systems exhibited good separation and extraction performance for both neutral and ionizable PFASs. The presence of a cyano group adjacent to bromine leads to increased polarization of the C–Br bond, resulting in increased strength of the Br···F contact, which provides selectivity to some extent. For fatty acids, their disruptive effect on eutectic systems is greater because of the relatively strong aggregation that affects DES structuring. For PFASs, different categories of target monomers are confined in the DES cavities and interact with the surrounding solvent through abundant interaction sites (such as electrostatic attraction, N-H···F-C, O-H···F-C, O-H···O-H, and C≡N···O-H hydrogen bonds) without significantly disrupting the solvent structural properties by reducing the molecular mobility.","PeriodicalId":12768,"journal":{"name":"Green Chemistry Letters and Reviews","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
