Hence, comparative profiling of <i>Artemisia</i> species in Egypt (<i>A. annua</i>, <i>A. herba-alba</i>, <i>A. monosperma</i> and <i>A. judaica</i>) and their authentication is of great interest. An integrated approach of GC-MS, HPTLC-image analysis and near-infrared (NIR) spectroscopy was implemented for their fingerprinting, discrimination and authentication. GC-MS analysis revealed the phytochemical profile of their volatile oils identifying compounds spanning monoterpenes, sesquiterpenes, diterpenes and non-terpenoid compounds. The major chemical components were highlighted as camphor, β-caryophyllene and germacrene D in <i>A. annua</i>, camphene, cis-pinocarveol, trans-chrysanthenyl acetate and cis-chrysanthenyl acetate in <i>A. herba-alba</i>, α-pinene, β-pinene, α-terpinolene and (-)-spathulenol in <i>A. monosperma</i>, finally, camphor, piperitone and trans-ethyl cinnamate in <i>A. judaica</i>. HPTLC-image analysis allowed tracking chemical markers in their total alcoholic extracts. Artemisinin was detected only in <i>A. annua</i> while scopoletin was identified as a major characteristic coumarin in <i>Artemisia</i> species. Phenolic acids and flavonoids were also discovered in the different species. Finally, NIR spectroscopy allowed profiling and authentication of their powders revealing prominent spectral characteristics correlated to the chemical markers identified by GC-MS and HPTLC. Then, multivariate analysis facilitated classification and discrimination of the species. Additionally, PLS regression analysis was utilized for quality control of powdered <i>A. annua</i>, being an important industrial crop, by detecting its adulteration with other species in limits of detection less than 1.5%.

Pomegranate peel was characterized by using X-ray diffraction (XRD), Brunauer, Emmet ve Teller (BET), scanning electron microscopy (SEM), Fourier transform infrared spectrophotometer (FT-IR), thermogravimetric analysis (TGA), and zeta potential. For both dyes, pH, adsorbent amount, contact time, salt effect, and wastewater parameters were investigated in the batch system, while adsorbent amount and flow rate parameters were investigated in the continuous system. The adsorption results of both dyes on pomegranate peel indicate that they fit the pseudo-second-order kinetic model. The adsorption isotherms of both dyes were found to be compatible with the Langmuir isotherm model. In the thermodynamic study, it was determined that the adsorption process was spontaneous (∆G°&lt;0) and exothermic (∆H°&lt;0). It was decided that pomegranate peel is a suitable adsorbent for the adsorption of BBR and VBR dyes. Finally, the adsorption yields for removing BBR and VBR from wastewater using pomegranate peel were 90.38% and 100%, respectively. This result shows that the high adsorption efficiency obtained for both dyes makes it possible for pomegranate peel to be widely applied as an adsorbent in wastewater treatment.</p></div>","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bmcchem.biomedcentral.com/counter/pdf/10.1186/s13065-025-01476-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this critical gap by pioneering the application of machine learning techniques to develop robust UV spectrophotometric approach for the simultaneous quantification of MOM and OLO, along with two genotoxic impurities: 4-dimethylamino pyridine (DAP) and methyl para-toluene sulfonate (MTS). By simultaneously determining these highly concerning genotoxic impurities and active pharmaceutical ingredients, this method underscores its paramount significance in upholding rigorous pharmaceutical quality standards and safeguarding patient safety. Applying the multilevel-multifactor experimental design, the calibration set was meticulously chosen at five different concentrations, yielding 25 calibration mixtures with central levels of 4, 46.5, 2.5, and 3 µg/mL for MOM, OLA, MTS, and DAP, respectively. The key innovation lies in the strategic implementation of the Kennard-Stone Clustering Algorithm to create a robust validation set of thirteen mixtures, resolving the limitations of reported chemometric methods’ random data splitting. This approach ensures unbiased evaluation across the full concentration space, improving the method’s reliability and sustainability. The robustness of this approach was rigorously tested using five distinct chemometric models: principal component regression, classical least squares, partial least squares, genetic algorithm-partial least squares, and multivariate curve resolution-alternating least squares, demonstrating its broad applicability across diverse modeling techniques. All models successfully determined all components with excellent recovery, low bias-corrected prediction, and adequate limits of detection. The Greenness Index Spider Charts and the Green Solvents Selection Tool were used to choose environmentally conscious solvents. A comprehensive sustainability assessment employed six state-of-the-art tools, including the national environmental method index, complementary green analytical procedure index, analytical greenness metric, blue applicability grade index, carbon footprint analysis, and the red-green-blue 12 metrics. Favorable results across all metrics affirmed the method’s eco-friendliness, real-world applicability, and cost-effectiveness, supporting sustainable development goals in pharmaceutical quality control processes.</p></div>","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bmcchem.biomedcentral.com/counter/pdf/10.1186/s13065-025-01391-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
