In order to improve the utilization and added-value of mango peel, effects of the ultrasound-assisted enzymatic method on the extraction rate of mangiferin from mango peel were investigated by single-factor tests (enzyme addition amount, enzymolysis time, ethanol concentration, ultrasonic temperature, ultrasonic power, and ultrasonic time), and the extraction process was optimized by Box-Behnken response surface. The antioxidant activity and antidiabetic assay of mangiferin in vitro were studied. The results showed that enzymolysis time 44 min, enzyme addition amount 0.1%, ethanol concentration 70%, ultrasonic power 300 W, ultrasonic temperature 66°C, and ultrasonic time 45 min were the optimal extraction process parameters. Under these conditions, the extraction rate of mangiferin was 3.63% ± 0.04%, which was not significantly different from the model prediction value (3.71%), and it was 3.90 times and 1.78 times that of single cellulase and ultrasonic extraction, respectively.

By comparing different extraction methods, HS-SPME-GC-MS was selected as the optimal extraction condition. Regarding Head-space Solid-Phase Microextraction and Gas Chromatography-Mass Spectrometry (HS-SPME-GC-MS), single-factor condition optimization and response surface analysis were carried out for different fiber coatings, equilibrium time, extraction temperature, and extraction time. Eventually, 75-μm CAR/PDMS fiber head was chosen, with an equilibrium time of 15 min, and extraction was conducted at 70°C for 57 min as the optimal HS-SPME extraction conditions. Furthermore, a differential analysis of the volatile components of five Lauraceae plants from different genera was performed, and differential metabolites were screened out respectively.

Both drugs have well-documented efficacy and safety profiles, providing synergistic pain relief through complementary mechanisms of action. IBU not only offers central analgesic effects but also inhibits cyclooxygenase (COX) enzymes, particularly COX-1 and COX-2, thereby reducing prostaglandin synthesis at the site of pain to deliver both analgesic and anti-inflammatory benefits. Despite the growing use of this combination, a comprehensive review focusing on the analytical methods for its determination has not yet been published. This review aims to bridge that gap by presenting an extensive compilation of documented analytical methods for the quantification of IBU and PAR in both bulk and pharmaceutical formulations. It serves as a valuable resource for researchers and professionals seeking detailed insights into the diverse techniques employed for accurate and precise analysis of these FDCs. Through a systematic search of major scientific databases, including Science Direct, Springer Link, PubMed, Scopus, and Google Scholar, the review identifies the most commonly utilized methods, such as high-performance liquid chromatography (HPLC), gas chromatography (GC), high-performance thin-layer chromatography (HPTLC), ultraviolet (UV)/Visible spectrophotometry, Fourier-transform infrared spectroscopy (FTIR), and micellar electrokinetic chromatography (MEKC). Notably, HPLC and UV/Visible spectrophotometry were the most frequently reported, each accounting for 37.9% of studies.

Recent studies have shown that DPP IV is not only involved in normal physiological processes but also closely related to various pathological processes, making it an important target for the treatment of metabolic diseases. Deciphering the relevance of DPP IV to human diseases and screening the inhibitors of DPP IV requires reliable tools, which can sense the function of this key enzyme in complex biological samples. Therefore, we aimed to construct a simple and easy-to-use assay for human DPP IV activity in a living cell system to achieve highly sensitive and selective detection of DPP IV function and further screening for its inhibitors. An easy-to-use assay for DPP IV function at the cellular level with a specific fluorescence probe toward DPP IV using a fluorescence microplate reader was the first to be established. Then, the experimental conditions were systematically optimized in terms of cell density, concentrations of probe, and incubation time. After that, the efficacy of the positive DPP IV inhibitors was evaluated by utilizing the optimized easy-to-use assay. Overall, this easy-to-use assay exhibited good precision, robustness, high throughput, and reliability. In conclusion, a straightforward and user-friendly method has been developed for detecting DPP IV activity in live cells, enabling accurate assessment of DPP IV function and efficient screening of inhibitors. This method may hold significant implications for advancing understanding of the relationship between DPP IV and disease progression, early disease diagnosis, and personalized drug therapy.","PeriodicalId":14974,"journal":{"name":"Journal of Analytical Methods in Chemistry","volume":"2025 ","pages":"1616740"},"PeriodicalIF":2.3,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12185214/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144475351","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}

The abuse of these fragments by athletes is the current trend in doping. Therefore, a competitive ELISA format is needed; however, only a limited number of kits on the market are based on this principle. Furthermore, these kits are designed to detect and quantify hGH only in blood plasma, serum or tissue cultures. When analysing a nutritional supplement containing hGH using one of these ELISA kits, a false negative result was observed. In the present work, two competitive ELISA methods for the detection of hGH in illegal nutritional supplements were developed. The development of the methods involved the selection of suitable immunoreagents and their combinations with subsequent optimisation of the conditions for their use. The methods were then characterised (with LOD 0.4 and 18.4 ng/mL, according to the primary antibody) and applied to analyse real nutritional supplements. In all 34 samples suspected of containing hGH, the hormone was detected using both ELISA methods and subsequently confirmed by LC-UV and LC-MS.

In an effort to decrease expenses, stigmas of safflower (Carthamus tinctorius), which closely resemble saffron, are often added to pure saffron as a typical method of adulteration. Hence, by quantifying the extent of eugenol modifications in the samples and employing ion mobility spectrometry (IMS) to identify and quantify these adulterants in saffron, the objective of this research has been accomplished. The analysis of eugenol showed a significant increase in peak intensity as the concentration of safflower increased in laboratory-prepared samples of pure saffron and safflower as well as the mixture of them (25%, 50%, 75%, and 100%, v/v). In the subsequent phase, a total of 20 saffron samples procured from nearby markets were examined under an optical microscope to identify any adulteration with safflower. Five samples, which included saffron containing safflower at varying concentrations (8.3%, 14.9%, 19.4%, 25.4%, and 33.7% W/W), were chosen for additional IMS analysis. The results showed that the peak intensity of eugenol climbed from 0.20 to 0.28 mV by augmenting the safflower content in saffron. Therefore, by increasing the level of safflower contamination in saffron, the concentration of eugenol in the IMS rose. The outcomes demonstrated that the selection method effectively detects saffron adulterated with safflower, improving both precision and specificity, and could aid in defining standard quality control procedures for saffron authenticity and quality.","PeriodicalId":14974,"journal":{"name":"Journal of Analytical Methods in Chemistry","volume":"2025 ","pages":"6366923"},"PeriodicalIF":2.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12133364/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144215908","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}
