COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
Even though both models showed good correct classification rates (%), the multiclass model could give problems when two or more of the targeted plants are present, since it is only able to classify with ...
chromatographic fingerprinting for the detection of herbal adulteration and herbal fraud in plant food supplements
a series of plants it can become more tedious (Ichim, 2019). Here an approach is presented based on chromatographic fingerprinting and chemometrics to perform a targeted screening for three and two regulated ...
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 ...
Detection of regulated and prohibited plants in plant food supplements
chromatographic profile of the targeted plant in the mixture and classify it as positive or negative for the targeted plant. For this first topic of the break-out session on herbals, the questions that are ...
Characterization and risk identification of falsified medicines and adulterated dietary supplements
selectivity and specificity for the detection of targeted plants in mixtures. It stands to reason that collaborations on these topics would be beneficial for both the European and the Chinese policy makers to ...
A strategy based on fingerprinting and chemometrics for the detection of regulated plants in plant food supplements from the Belgian market: two case studies
confirmed based on binary classification models calculated with the chromatographic data obtained for the suspected plant. In general, good classification models were obtained for each of the targeted ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
in terms of resolution and symmetry factor for the targeted peptide set. Hence, the operational conditions were further optimised for the identification of illegal preparations via mass spectrometry ...
