Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
order to tackle this problem, a feasibility study based on a combination of chemometrics and multidimensional fingerprints recorded using chromatography was carried out. Chromatographic fingerprints ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
one plant in contrast to using different binary models. Therefore, binary models might be preferred over multiclass models. Furthermore, it can also be concluded that a combination of chemometrics and ...
Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
the combination of multidimensional fingerprinting data with chemometrics was feasible for the identification of regulated plants in complex botanical matrices. Health Topics: Médicaments illégaux ...
Clustering of Tadalafil API Samples According to their Manufacturer in the Context of API Falsification Detection
Official Medicines Control Laboratory Network (GEON), on tadalafil. A classical market surveillance study, evaluating compliance to the European Pharmacopoeia, was combined with a fingerprint study, the ...
Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements
5 wavelengths, 254 nm and with the combined fingerprint. The multi and combined wavelengths approach provides a characteristic and specific fingerprint with more information at different wavelengths than only 254 ...
OMCL testing and the API working group: Part of the solution?
of API s is real and was shown by several crisis. Therefore the API- WG organizes atypical market surveillance studies (MSS), where an MSS (analysis according to the Ph. Eur.) is combined with ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
not suited for onsite analysis. Near infrared spectroscopy combined with chemometric tools has the potential for quantitative and qualitative prediction of plant natural products compounds [6]. In ...
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
years some studies were combined with a fingerprint study of the API s. The idea is to obtain a fingerprint for each manufacturer of the API under investigation, allowing the OMCL network to identify ...
European fingerprint study on omeprazole drug substances using a multi analytical approach and chemometrics as a tool for the discrimination of manufacturing sources
Analysis and Hierarchical Clustering Analysis. Data were analyzed separately and in combination (data fusion), allowing us to conclude that NMR and XRPD were suitable to differentiate samples originating ...
