Using a Waters X-Select HSS T3 column for the separation of recycled TPA and eight impurities, and a mobile phase of H2O/CH3CN containing 0.1% trifluoroacetic acid (TFA) with detection by UV at 250 nm, baseline separation of all compounds was achieved in ˂17 min. Four different mobile phase acidic additives were tested, the results indicating that mobile phases with lower pH provided better separation of the compounds with accompanying improved peak shapes. Among all the acidic additives tested in this study, a mobile phase containing 0.1% TFA demonstrated the highest resolution and the best peak shapes. It was concluded that by suppressing the ionization of the acidic compounds contained in the samples through increased acidity of the mobile phase, better peak shapes and higher resolution could be achieved. The amount of increased mobile phase acidity was based in part on the pKa values of the analytes and adjusted so as to eliminate as much as possible any dissociation of the organic acids. A comparison of a standard addition method versus an external calibration curve approach for the quantification of impurities showed similar results, even for relatively low-concentration analytes at levels below 10 ppm. The aspects often linked with validated analytical methods were addressed including linearity, limit of detection, limit of quantitation, sensitivity and selectivity, addressing the criteria set forth in the acronyms of the QuECHERS method description, that is quick easy, cheap, effective, rugged and safe.","PeriodicalId":15430,"journal":{"name":"Journal of chromatographic science","volume":"63 5","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144009468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to develop and validate a simple and rapid quali-quantitative High Performance Thin Layer Chromatography (HPTLC) densitometry method to detect ephedrine, the most abundant alkaloid of Ephedra plant, and to analyze free sale ephedra-based capsules. This quick, simple and low requirement method is cost-effective and allows screening up to 19 samples all together in a single layer. During the development of this method, an extraction solvent mixture composed of methanol/water (2:1, v/v) and a mobile phase constituted of ammonia/methanol/dichloromethane (1:10:40, v/v/v) gave the best results. The identity and purity of ephedrine peak were confirmed by matching Rf value and UV-spectrum with its reference standard. Lastly, samples were quantitated by densitometry at 500 nm after ninhydrin derivatization. Linearity was obtained in the concentration range of 0.062-0.146 μg/band. Limit of detection and limit of quantification (LOQ) were found to be 0.0020 μg/band and 0.0067 μg/band, respectively. This technique is useful to screen multiple samples at the same time with a limited use of solvents and reagents so that it can be considered a fast and simple procedure.","PeriodicalId":15430,"journal":{"name":"Journal of chromatographic science","volume":"63 4","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143987871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dopamine (DA) can form a PDA layer on Fe3O4@1C NPs surface through self-polymerization to form Fe3O4@1C@PDA. As a surface modifier of DA, PDA offered more adsorption sites to AAI due to π-π stacking, hydrogen bonding and electrostatic interactions.
