Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
each plant. For both binary modelling and multiclass modelling, a ccr% above 85% for external test set validation was observed for all the plants. As a proof of concept, 12 weight-loss PFS, seized by ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
square – discriminate analysis. A minimum of 86% correct classification rate for external test set validation (17 sample for binary dataset and 59 samples for multiclass dataset) was observed for all ...
Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
Pressure Liquid Dietary Supplements Discriminant Analysis Least-Squares Analysis Plants Abstract: The popularity of plant food supplements has seen explosive growth all over the world, making them ...
Clustering of Tadalafil API Samples According to their Manufacturer in the Context of API Falsification Detection
falsified samples. In total, 46 tadalafil API samples from 13 different manufacturers were collected. For all samples fingerprint data was collected through analysis of impurities and residual solvents, mass ...
Detection of regulated and prohibited plants in plant food supplements
and advanced bio-informatics in order to identify all plants present in the mixture. The second project focusses on the use of chromatographic fingerprints and chemometrics in order to recognize the ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
reflectance mode with the Near Infrared Reflectance Accessory (NIRA)) and dispersive NIR handheld devices combined with chemometrics. All pretreated spectra were analysed with chemometrics. Principal component ...
Contents of Amoxicillin Drugs Dispensed in Goma, Democratic Republic of Congo
drugs, but all samples contained the active ingredients as claimed on the packages. We found under dosage of 90% and less in 3 of the 15 amoxicillin samples and in none of the 9 combined specimens. ...
GEONs API fingerprint project: Selection of analytical techniques for clustering of sildenafil citrate API samples
chromatography for residual solvents, X-ray diffraction and Nuclear Magnetic Resonance (NMR) spectroscopy. Chemometrics applied to the collected data showed that all manufacturers could be discriminated based on ...
The occurrence of non-anatomical therapeutic chemical-international nonproprietary name molecules in suspected illegal or illegally traded health products in Europe: A retrospective and prospective study.
collected from the illegal market, while only 3% originated from a legal source. For the rest of the samples, categorisation was not possible. Moreover, 69% of all the reported samples were presented as ...
Impurity profiling of the most frequently encountered falsified polypeptide drugs on the Belgian market
drugs. Subsequent speciation of As confirmed the elevated concentrations for As and demonstrated that all As was present in the more toxic inorganic form. Together with the (sometimes) high amount of ...
