Society, Issue Italian Chemical Society, Novara, Italy (2023) Keywords: fingerprinting plant food supplements Abstract: An undeniable increase in consumption and sales of plant food supplements (PFS), ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
concerns, necessitating an efficient screening approach for detection of the regulated plants in plant food supplements. This study aims at developing a chemometric approach coupled with fingerprinting for ...
From b to y ions, a decade of experience with peptide and protein analysis
recombinant expression technologies, and peptide synthesis have led to an increased development of protein and peptide therapeutics. Due to improved and simplified manufacturing techniques, disregard for patent ...
Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements
by the ease with which they can be purchased from various illegal channels, necessitating an efficient screening approach. This study aims to develop a multidimensional approach using chromatographic ...
chromatographic fingerprinting for the detection of herbal adulteration and herbal fraud in plant food supplements
especially when purchased via internet, an interesting platform for the trade in fraudulent products (Mosihuzzaman and Choudhary, 2008). In this context two possible health threats may occur: (a) the PFS does ...
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.
performed a comparison of the use of RRF s and linear relative response factor models (LRRFM) for the quantification of targeted low-dosed compounds using an alternative standard, since it is known that ...
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
GC- FID for total-tetrahydrocannabinol detection and quantification with an officially validated method. The analysis of these products was performed by FT- NIR spectrometer (spectra were recorded in ...
Characterization and risk identification of falsified medicines and adulterated dietary supplements
medicines is not enough to evaluate their risk and that a broader characterization of the products is necessary for a correct risk evaluation. In another part of the project an onsite infrared based approach ...
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.
sports supplements listing deterenol as an ingredient contained 9 prohibited stimulants and 8 different mixtures of stimulants, with as many as 4 experimental stimulants per product. These cocktails of ...
