An environmentally friendly N-CQDs-based fluorescence sensor for gabapentin detection is developed, with optimal conditions and high selectivity, accuracy, precision in real sample analysis.
Cynara cardunculus L. with its three botanical varieties are presented as potential food and drug resources. Its young flower heads commonly consumed a principal part of different Mediterranean dishes, especially the globe artichoke, whereas plant parts considered sources valuable phytoconstituents, mainly polysaccharides, polyphenols. These chemicals contribute to nutrition, industry, bioactivities, including hepatic- cardiovascular protection inflammation disorders. A holistic comparative...
Tongkat ali commonly known as Malaysian Ginseng (Eurycoma longifolia) is a herbal root worldwide available in nutraceuticals, either crude powder or capsules blended with other products. Herein, multiplexed metabolomics approach based on nuclear magnetic resonance (NMR) and solid-phase microextraction combined gas chromatography-mass spectrometry (SPME-GC-MS) was applied for authentic tongkat extract vs some commercial products quality control analysis. NMR metabolite fingerprinting...
Herbs of the Umbelliferae family are popular spices valued worldwide for their many nutritional and health benefits. Herein, five chief umbelliferous fruits viz., cumin, fennel, anise, coriander caraway were assessed its secondary metabolites diversity along with compositional changes incurring upon roasting as analyzed via ultra-high performance liquid chromatography coupled to photodiode array electrospray ionization mass detectors UHPLC-qToF/MS. A total 186 annotated, according...
ABSTRACT This study introduces a novel synchronous spectrofluorimetry coupled with chemometric tools for the determination of tenofovir and dolutegravir antiretroviral drugs. Utilizing partial least squares regression (PLS) fine‐tuned by genetic algorithm as variable selection tool, developed models demonstrate greater sensitivity, cost‐effectiveness, reduced environmental impact compared to traditional HPLC methods. The model's validation was further confirmed using external in addition QC...
A sensitive “turn-off” fluorescent method using MPA-CdTe quantum dots was developed for the selective determination of lurasidone in pharmaceutical formulations, spiked plasma, and environmental water samples.
In the present study, a simple, rapid and cost-effective analytical method was developed for simultaneous determination of three commonly prescribed cardiovascular drugs: propranolol, rosuvastatin valsartan. The employed artificial neural networks (ANN) to model relation between UV absorption spectra drugs their concentrations. An experimental design 25 samples as calibration set, central composite 20 used validation set. firefly algorithm (FA) evaluated variable selection procedure optimize...
