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 ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
hemp or cannabis flowers containing less than 0.2% m/m of Δ9- THC. Conclusion Near infrared spectroscopy allows to discriminate various samples. The difference is caused by the totality of compounds of ...
GEONs API fingerprint project: Selection of analytical techniques for clustering of sildenafil citrate API samples
14 different manufacturers were collected throughout the Network. Fingerprint data was collected through Mid-Infrared spectroscopy, Raman spectroscopy, liquid chromatography for related substances, gas ...
Nine prohibited stimulants found in sports and weight loss supplements: deterenol, phenpromethamine, oxilofrine, octodrine, beta-methylphenylethylamine, 1,3-dimethylamylamine, 1,4-dimethylamylamine, 1,3-dimethylbutylamine (1,3-DMBA) and higenamine.
