Screening of plant food supplements for fraud concerning the presence of medicinal or regulated plants based on multi-dimensional chromatographic fingerprints
properties: Ilex Paraguariensis, Hoodia Gordonii, Garcinia Cambogia, Aristolochia Fanghi. In a first step an approach was developed recording chromatograms at different UV wavelength, followed by an approach ...
Simultaneous quantification of Ibuprofen and Paracetamol in combined tablet formulations by UV–VIS spectrophotometry and chemometric modelling
Different sources of variability, not related with concentration differences between the samples, were incorporated into the calibration data in order to obtain stable models which wouldn’t be affected from ...
The strategic change of the API fingerprint programme: from verification of authenticity of API sources to identifying potential quality issues
analysis to Ph. Eur. Monographs, other types of analysis were performed in order to obtain data, allowing to distinct the different API samples according to their origin or manufacturer. The idea was to ...
Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
commonly encountered in PFS claiming weight-loss as indication. However, PFS usually are composed of mixtures of different plants resulting into a not so straightforward approach for their detection. In ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
campaigns and availability through various different platforms can be rendered as catalysts for their popularity. In regards to the Belgian market, suspicious samples entering the border generate serious ...
Clustering of Tadalafil API Samples According to their Manufacturer in the Context of API Falsification Detection
latter to obtain characteristic data for the different manufacturers, allowing the network laboratories to conduct authenticity tests for future samples, as well as to detect substandard and ...
Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements
fingerprinting at different wavelengths for identification of Tribulus terrestris in plant food supplements. A specific, selective and fast fingerprinting method for Tribulus (reference material obtained from the ...
Relative response factors and multiple regression models in liquid chromatography to quantify low-dosed components using alternative standards-proof of concept: total Δ9-THC content in cannabis flowers using CBD as reference.
have limited shelf-life properties. Also, in herbal matrices, multiple compounds could be necessary to be quantified, needing a whole series of different (related) reference standards. In these cases, ...
OMCL testing and the API working group: Part of the solution?
trends, new frontiers, EDQM, Issue EDQM, Rome, Italy (0) Abstract: Within the OMCL network different initiatives were taken to augment the analysis and market surveillance of API s used by different ...
Detection of regulated and prohibited plants in plant food supplements
Belgium the OMCL is regularly asked to perform analysis in this context, namely to identify/detect a certain plant in a herbal preparation, composed of a mixture of different plants. For this purpose the ...
