The objective of this study was to compare essential oils extracted from leaves, berries, and sap in terms of extraction yield, chemical composition, and antibacterial activity. Essential oils were extracted, characterized by GC-MS, and evaluated for antibacterial activity against H. pylori strains J99 and F29, as well as Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. The sap showed the highest yield (9.218%). GC-MS analysis revealed monoterpenes and sesquiterpenes as the main constituents, with α-pinene present in all samples. The leaf essential oil exhibited the strongest inhibition against H. pylori, exceeding the tested antibiotics against the F29 strain. These findings indicate that P. lentiscus leaves represent the most promising natural source for anti-H. pylori activity and suggest that the effect is due to synergistic interactions rather than α-pinene alone.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"73 1","pages":"267-278"},"PeriodicalIF":1.3,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147589311","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 crystallographic analysis indicates that Cd(II) center exhibits a distorted octahedral coordination geometry, where two phen ligands form a bidentate chelate, while the deprotonated 2-methyl-3-hydroxyquinoline-4-carboxylate anion (L⁻) acts as a charge-balancing lattice anion.

Due to its inherent stability and rigidity, this chemical may be suitable as a host for host-guest interactions. Therefore, the sulfonated calixarene was used to study its complexation properties with the dyes, namely Acid Red 88 (AR88) and Acid Orange 7 (AO7) as adsorbing guests. Calculated formation constants (Kf) for the SCX4/dyes complexes were estimated from comparison of the absorption intensities. The formation constants were 5.1∙104 M-1 and 5.2∙104 M-1, correspondingly. Calculated stoichiometric ratios of the complexes were evaluated via Benesi-Hildebrand diagrams, which gave a ratio of 1:1. The equilibrium adsorption data of Acid Orange 7 were evaluated via three adsorption isotherm models including Freundlich, Temkin and Langmuir. The adsorption isotherms showed compatibility with three different approaches. The findings suggest that the Freundlich model better covers this adsorption process. Using a DFT-based approximation revealed the preferred structure of SCX4 and its complex with Acid Orange 7.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"73 1","pages":"183-196"},"PeriodicalIF":1.3,"publicationDate":"2026-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147589206","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}

In this study, a liquid-liquid extraction (LLE) procedure coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed and validated for the simultaneous detection of 23 diuretics in whey protein supplements. The method was assessed for selectivity, linearity, matrix effect, recovery, precision, and sensitivity. Statistical evaluation using the Shapiro-Wilk and Levene's tests confirmed that most calibration residuals exhibited a normal distribution and homogeneity of variance, ensuring the reliability of the regression model. The method demonstrated excellent linearity (R² = 0.980-0.999) and low method detection limits (MDLs, 0.39-2.73 ng/g). A total of 58 commercially available whey protein supplements were analysed, and bendroflumethiazide (D4) was detected in 12 samples, with concentrations ranging from 1.4 to 40.4 ng/g. These findings highlight the applicability of the validated method for routine monitoring and underscore the urgent need for stringent quality control and regulatory oversight in the sports supplement industry to protect consumer health and maintain fair competition.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"73 1","pages":"197-206"},"PeriodicalIF":1.3,"publicationDate":"2026-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147589224","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}
