Chemometrical analysis of fingerprints for the detection of counterfeit and falsified medicines
research oncounterfeit medicines has already been performed andpublished in literature. This review aims at providing anupdated overview of the use of fingerprints and subsequentmultivariate (chemometrical) ...
Chemometrics and chromatographic fingerprints to classify plant food supplements according to the content of regulated plants.
regulated or toxic plants is an important issue, especially when the products are purchased from irregular sources. This paper focusses on this problem by using specific chromatographic fingerprints for five ...
Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.
applying more sophisticated fingerprint approaches or identification tests described in several national and international pharmacopoeia. As a proof of concept five real suspicious samples were successfully ...
The use of Stationary Phase Optimized Selectivity Liquid Chromatography for the development of herbal fingerprints to detect targeted plants in plant food supplements.
fingerprints, to be used for the detection of targeted plants in plant food supplements. Three commonly used plants in plant food supplements and two regulated plants were used to develop fingerprints with SOS- ...
Chromatographic fingerprinting as a strategy to identify regulated plants in illegal herbal supplements.
explore the potential use of chromatographic fingerprinting to identify plants present in herbal preparations intended for the treatment of ED. To achieve this goal, a HPLC- PDA and a HPLC- MS method were ...
Clustering and diagnostic modelling of slimming aids based on chromatographic and mass spectrometric fingerprints
highly informative fingerprints. Three types of fingerprints were acquired (PDA, Total Ion Chromatograms (TIC), and MS fingerprints) which were used in the chemometric data analysis. Both unsupervised ...
